Paolo Feraboli (born September 20, 1976) is a carbon fiber technology inventor and businessman. He is the founder and CTO of Gemini Composites, LLC, a wholly owned subsidiary of Mitsubishi Chemical Carbon Fiber and Composites, and founder and former Director of the Automobili Lamborghini Advanced Composite Structures Laboratory (ACSL). He is known for having invented the Forged Composite technology, and his contributions to the Lamborghini Sesto Elemento and Aventador programs.
Paolo Feraboli was born and grew up in Bologna, Italy. He graduated in mechanical engineering at the University of Bologna in 2002 with a Master's thesis on turbulent heat transfer. [1] He received his doctorate in mechanical engineering from the University of California at Santa Barbara in 2005 with a dissertation on impact of carbon fiber composite structures under the guidance of Professor Keith T. Kedward. Among his mentors during his doctoral studies were composite pioneers such as John Halpin of Air Force Research Laboratory, [2] and Larry Ilcewicz of the Federal Aviation Administration. [3] [4]
The relationship between Feraboli and Automobili Lamborghini S.p.A. started in 2001–2002 with an internship at the Esperienza Compositi (R&D composites division) at the headquarters in Sant'Agata Bolognese. [5] [6] Under the supervision of Attilio Masini, Andrea Bonfatti, and Maurizio Reggiani, Feraboli worked on the development of the Murciélago and Murciélago Roadster carbon fiber components in the body and chassis. [7] [8] [9]
After years of study and research in the United States, Lamborghini engaged Feraboli in 2007 to spearhead the development of new carbon fiber technologies as well as monocoque and chassis concepts while he was serving as Assistant Professor at the University of Washington. The successful collaboration led to the formal establishment of the Lamborghini Lab which was located on the UW campus from 2009 until 2013. After inventing Forged Composite technology for Lamborghini, Feraboli left the University in 2014 to focus on its further commercialization for the Italian car manufacturer. In order to do so, he opened a new stand-alone Lamborghini Lab which was to be the only Lamborghini R&D organization outside of the headquarters in Italy. The new facility, inaugurated in 2016, included the Carbon Fiber Technology Gallery and Lamborghini Academy of Carbon Arts & Sciences. [10] [11] [12]
The legacy of Paolo Feraboli with Lamborghini is notable in the following achievements:
Feraboli was introduced to the world of carbon fiber in aerospace by one of the founding fathers of composite technologies, his UCSB doctoral advisor Professor Keith Kedward. Professor Kedward was a fellow of AIAA, fellow of American Society of Composites (ASC), winner of the prestigious AIAA-ASC Starnes Award. [23]
Feraboli's research on aircraft foreign object damage (FOD) brought him to the NASA Langley Research Center in 2004–2005. There he conducted experiments and analysis on impact damage on carbon fiber structures for the blended wing body project, along with other projects in the Mechanics and Durability branch. [24]
In 2005, Feraboli was hired by the University of Washington to expand the recently established Boeing/FAA Center of Excellence for composites research, guided by the FAA Chief Scientist for Composites Dr. Larry Ilcewicz. [25] In his new laboratory, Feraboli pioneered the first research in the public domain in chopped carbon fiber technology for commercial transport aircraft, [2] [26] [27] [28] [29] lightning strike damage on composites, [30] [31] [32] and composite crashworthiness. [33] [34] [35] [36] [37] Because of his contributions in these fields, he received awards from the Japan Society for Composite Materials (JSCM), [38] American Society for Composites (ASC), [39] and MIL-17. [40]
While a professor at UW, Feraboli also worked in the Boeing 787 Technology Integration team in Everett, WA under Dr. Alan Miller and Dr. Patrick Stickler. Within this group, he conducted a critical review of all 787 composite analysis methods, including in-house tools and external software, and acted as the liaison with the Structural Methods and Allowables group, under William Sheridan. [41]
Feraboli is the founder and former chairman (2004-2012) of the Working Group on Composite Crashworthiness of the CMH-17 (formerly MIL-HDBK-17), the long established DoD/DoT organization aimed at providing recommendations on the use of composite materials.
Ever since his Boeing and FAA experience, Feraboli has been a strong advocate for the Building Block Approach, also known as Certification by Analysis supported by test evidence. He has often spoken publicly to caution on the use of so-called predictive analysis tools for composites, especially in the area of crashworthiness. [42]
In 2012 Feraboli incorporated a design and engineering firm called Gemini Composites, which focused on the commercialization of Forged Composite technology. Such breakthrough technology requires specific know-how in material, process, and design alike, and Gemini offered these services for OEMs worldwide and across multiple industries.
At Gemini, Feraboli assisted OEMs in the development of several consumer goods, including:
Gemini Composites supported several other OEMs in developmental and research projects, including Northrop Grumman, Lockheed Martin, Toyota, Ducati, Volvo, Honda North America, and Nike.
In March 2017, Gemini Composites was acquired by Mitsubishi Rayon Co. (now Mitsubishi Chemical), [47] to expand the use of Forged Composite technology under the new name Forged Molding Compound (FMC). [48]
In 2017, Toyota introduced a version of Forged Composite technology in the production of the Prius prime (PHV). [49] The inner structure of the rear hatch is the first carbon fiber component used in a mass-produced vehicle thanks to the unique benefits of the new FMC technology. [50] Mitsubishi Chemical, supplier of the Prius FMC material, is now the world's largest producer of Forged composite raw material worldwide. [51]
While at Gemini, under the new MCC ownership, Dr. Feraboli trademarked the name Forged Molding Compound, or FMC, to indicate the commercial name of the CFSMC marketed by MCC. [52] The name uniquely identifies the MCC material as opposed to the Forged Composite, trademarked by Automobili Lamborghini SpA, and the more generic Forged Carbon, which is not trademarked and is used by many enterprises such as Union Binding Company.
Between 2017 and 2021, Dr. Feraboli supported Mitsubishi Chemical by leading the Global Engineering team, which was spread between Japan, USA, and Europe, and was tasked with the development of material property data and FEA analysis method generation for carbon fiber technology. [53]
The last development projects Dr. Feraboli brought to life while at Gemini were presented at the JEC show of May 2022 in Paris, France. These included the automotive FMC suspension arm, [54] which was innovatively engineered to meet and exceed the performance, weight and cost targets of the production forged aluminum wishbone arm. The design and fabrication process were patented [55] and showcased also at the automotive SPE conference in April 2021. [56] Finally, the rear subframe of the Ducati Hypermotard, which was developed in 2017-2019, was designed to be used as a 1-to-1 FMC replacement for the cast aluminum production part, and met all durability requirements with minimal re-engineering. [57]
After the completion of the technology transfer from Gemini to MCC, Dr. Feraboli exited the company to join Rivian Automotive in September 2021, as Sr. Lead engineer in the Prototypes and Special Projects division. Shortly after, Rivian launched the production of the R1T electric adventure truck and became listed on the Nasdaq market, the 5th largest IPO in the US history. [58] In August 2022 Dr. Feraboli joined the Advanced Development Projects division at Blue Origin, which develops projects such as the Orbital Reef and Human Landing System, as Director of Mechanical, Material and Structural Engineering.
For his contributions in the field of carbon fiber composites, Paolo Feraboli has received awards from the American Society for Composites, [39] [59] the Japan Society for Composite Materials, [38] and the MIL-HDBK-17. [60] He also holds an honorary research professor position at the Nagoya Institute of Technology in Japan. [61]
A composite material is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.
Carbon fibers or carbon fibres are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, motorsports, and other competition sports. However, they are relatively expensive compared to similar fibers, such as glass fiber, basalt fibers, or plastic fibers.
Pre-preg is a composite material made from "pre-impregnated" fibers and a partially cured polymer matrix, such as epoxy or phenolic resin, or even thermoplastic mixed with liquid rubbers or resins. The fibers often take the form of a weave and the matrix is used to bond them together and to other components during manufacture. The thermoset matrix is only partially cured to allow easy handling; this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Hence, composite structures built of pre-pregs will mostly require an oven or autoclave to cure. The main idea behind a pre-preg material is the use of anisotropic mechanical properties along the fibers, while the polymer matrix provides filling properties, keeping the fibers in a single system.
Araldite is a registered trademark of Huntsman Advanced Materials referring to their range of engineering and structural epoxy, acrylic, and polyurethane adhesives. Swiss manufacturers originally launched Araldite DIY adhesive products in 1946. The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950.
Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and filler.
Epoxy granite, also known as synthetic granite, is a polymer matrix composite and is a mixture of epoxy and granite commonly used as an alternative material for machine tool bases. Epoxy granite is used instead of cast iron and steel for improved vibration damping, longer tool life, and lower assembly cost, and thus better properties for stabilizing and housing machines.
Marine composite propellers are ship propellers, usually made from fiber composites like glass or carbon fibers. They are infused with a high-strength resin like epoxy or polyimide. These composites are made from strong, light, high-tech materials. Such composite propellers can be produced in several ways, including vacuum-infused molding and injection molding processes, depending on size and resin viscosity.
A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates, fibres or other reinforcements. They were first developed for structural applications, such as glass-reinforced plastic radar domes on aircraft and graphite-epoxy payload bay doors on the Space Shuttle.
Carbon fiber-reinforced polymers, carbon-fibre-reinforced polymers, carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic, also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications.
Z-pinning is a technique to insert reinforcing fibres along the Z-direction of continuous fibre-reinforced plastics. Z-pins can be made of metal or precured unidirectional composite fibres. It is designed for use within pre-preg technology; there is extensive experimental evidence that Z-pinning dramatically improves the resistance of the composite structure to delamination. The figure on the right shows a Z-pin inserted in between the fibres of the material. The pin spreads the fibres and creates an oval shaped gap that is filled with resin. The Z-pin prevents the composite from delamination. When a load is applied the cracks will typically form along the line of the opening.
The Lamborghini Aventador is a mid-engine sports car produced by the Italian automotive manufacturer Lamborghini. The Aventador’s namesake is a Spanish fighting bull that fought in Zaragoza, Aragón, in 1993. The Aventador is the successor to the Murciélago and was produced in Sant'Agata Bolognese, Italy.
Forged composite, commonly referred to as forged carbon, is a type of carbon fiber SMC material composed of small pieces of carbon fiber composite material that are pressed into shape as the resin sets. This is in contrast to most carbon fiber composites, which are made of larger continuous layers that are 'laid up' one at a time, often manually. Forged composite allows for a higher range of shapes to be formed with precision, relative to traditional carbon fiber. It was originally developed jointly between Lamborghini, Callaway Golf Company, and the Lamborghini Lab. It was unveiled at the 2010 Paris Motor Show in a Lamborghini concept car, the Sesto Elemento. The United States trademark for forged composite was filed on July 13, 2010, in the category Toys and Sporting Goods Products by Callaway Golf, while the trademark for Forged Composites was registered in 2018 in the automotive category by Lamborghini.
The Lamborghini Asterion LPI 910-4 is a concept hybrid car manufactured by Italian automobile manufacturer Lamborghini, which was unveiled at the 2014 Paris Motor Show. The car is named after a Minotaur called Asterion and was to be Lamborghini's first hybrid model. The half man – half bull Minotaur was chosen keeping in mind Lamborghini's tradition of naming their cars after a bull while alluding to its usage of different modes of power.
Transfer molding is a manufacturing process in which casting material is forced into a mold. Transfer molding is different from compression molding in that the mold is enclosed rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact. Compared to injection molding, transfer molding uses higher pressures to uniformly fill the mold cavity. This allows thicker reinforcing fiber matrices to be more completely saturated by resin. Furthermore, unlike injection molding the transfer mold casting material may start the process as a solid. This can reduce equipment costs and time dependency. The transfer process may have a slower fill rate than an equivalent injection molding process.
The Automobili Lamborghini Advanced Composite Structures Laboratory (ACSL), commonly referred to as the Lamborghini Lab, was a research and development facility based in Seattle, Washington from 2007 to 2018, which focused on the development of carbon fiber composite technologies for Automobili Lamborghini S.p.A. The ACSL also designed and developed carbon fiber products for other organizations in other industries. The hallmark technology pioneered by the Lamborghini Lab is the forged composite technology.
CFSMC, or Carbon Fiber Sheet Molding Compound, is a ready to mold carbon fiber reinforced polymer composite material used in compression molding. While traditional SMC utilizes chopped glass fibers in a polymer resin, CFSMC utilizes chopped carbon fibers. The length and distribution of the carbon fibers is more regular, homogeneous, and constant than the standard glass SMC. CFSMC offers much higher stiffness and usually higher strength than standard SMC, but at a higher cost.
In materials science, a polymer matrix composite (PMC) is a composite material composed of a variety of short or continuous fibers bound together by a matrix of organic polymers. PMCs are designed to transfer loads between fibers of a matrix. Some of the advantages with PMCs include their light weight, high resistance to abrasion and corrosion, and high stiffness and strength along the direction of their reinforcements.
Structural batteries are multifunctional materials or structures, capable of acting as an electrochemical energy storage system while possessing mechanical integrity.
Implant resistance welding is a method used in welding to join thermoplastics and thermoplastic composites.
