Forged composite

Last updated

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. [1] [2] [3] [4] It was unveiled at the 2010 Paris Motor Show in a Lamborghini concept car, the Sesto Elemento. [5] The United States trademark for forged composite was filed on July 13, 2010, in the category Toys and Sporting Goods Products by Callaway Golf, [6] while the trademark for Forged Composites was registered in 2018 in the automotive category by Lamborghini. [7]

Forged composite contains higher fiber volume content, which combined with higher variation in strand orientation, increases the average strength and reduce variability over standard carbon fiber. [8] The material is claimed to have one-third the density of titanium and equal or greater strength, [9] it is made from chopped carbon fiber tows immersed in a resin film which is then formed and cured. [10] It uses about 500,000 intertwined fibers per square inch. [5] The fibers contain intertwined and folded sheets of carbon atoms aligned with the length of the fiber, and the intertwining improved the fiber strength. The result is improved load carrying capacity as measured in bending per unit of mass. [11] Due to its chopped nature, it can be molded into much more complex geometries than traditional carbon fiber composites, and is suitable to make three-dimensional parts and parts which feature complex details such as thickness transitions, holes, compound curvature, etc.

Lamborghini uses forged composite for structural components, and interior trim and seats of its cars, the latter contributing to its winning of the JEC Composites Innovation Award for Automotive Interiors in 2016, due to the material's unique appearance. [12] Union Binding Company entered a partnership with the Lamborghini ACSL in order to develop a snowboard binding using forged composite technology. In 2014, the all-forged composite "Union FC" snowboard binding was launched and subsequently won the 2014 ISPO Product of the Year Award. [13]

Callaway claims the use of forged composite results in an average about 8 yards (7 m) greater distance per drive relative to traditional carbon fiber when used in its driving golf clubs. The material can contribute to reduced weight in vehicles.

Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components.

<span class="mw-page-title-main">Carbon fibers</span> Material fibers about 5–10 μm in diameter composed of carbon

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.

Fiberglass or fibreglass is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic.

Fibre-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.

Basalt fibers are produced from basalt rocks by melting them and converting the melt into fibers. Basalts are rocks of igneous origin. The main energy consumption for the preparation of basalt raw materials to produce of fibers is made in natural conditions. Basalt continuous, staple and super-thin fibers are produced and used. Basalt continuous fibers (BCF) are used for the production of reinforcing materials and composite products, fabrics and non-woven materials. Basalt staple fibers - for the production of thermal insulation materials. Basalt superthin fibers (BSTF) - for the production of high quality heat and sound insulating and fireproof materials.

A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion.

Micarta is a brand name for composites of linen, canvas, paper, fiberglass, carbon fiber, or other fabric in a thermosetting plastic. It was originally used in electrical and decorative applications. Micarta was developed by George Westinghouse at least as early as 1910 using phenolic resins invented by Leo Baekeland. These resins were used to impregnate paper and cotton fabric which were cured under pressure and high temperature to produce laminates. In later years this manufacturing method included the use of fiberglass fabric, and other resin types were also used. Today Micarta high-pressure industrial laminates are produced with a wide variety of resins and fibers. The term has been used generically for most resin impregnated fiber compounds. Common uses of modern high-pressure laminates include electrical insulators, printed circuit board substrates, and knife handles.

Nonwoven fabric is a fabric-like material made from staple fibre (short) and long fibres, bonded together by chemical, mechanical, heat or solvent treatment. The term is used in the textile manufacturing industry to denote fabrics, such as felt, which are neither woven nor knitted. Some non-woven materials lack sufficient strength unless densified or reinforced by a backing. In recent years, non-wovens have become an alternative to polyurethane foam.

<span class="mw-page-title-main">Biocomposite</span>

A biocomposite is a composite material formed by a matrix (resin) and a reinforcement of natural fibers. Environmental concern and cost of synthetic fibres have led the foundation of using natural fibre as reinforcement in polymeric composites. The matrix phase is formed by polymers derived from renewable and nonrenewable resources. The matrix is important to protect the fibers from environmental degradation and mechanical damage, to hold the fibers together and to transfer the loads on it. In addition, biofibers are the principal components of biocomposites, which are derived from biological origins, for example fibers from crops, recycled wood, waste paper, crop processing byproducts or regenerated cellulose fiber (viscose/rayon). The interest in biocomposites is rapidly growing in terms of industrial applications and fundamental research, due to its great benefits. Biocomposites can be used alone, or as a complement to standard materials, such as carbon fiber. Advocates of biocomposites state that use of these materials improve health and safety in their production, are lighter in weight, have a visual appeal similar to that of wood, and are environmentally superior.

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.

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.

Three-dimensional composites use fiber preforms constructed from yarns or tows arranged into complex three-dimensional structures. These can be created from a 3D weaving process, a 3D knitting process, a 3D braiding process, or a 3D lay of short fibers. A resin is applied to the 3D preform to create the composite material. Three-dimensional composites are used in highly engineered and highly technical applications in order to achieve complex mechanical properties. Three-dimensional composites are engineered to react to stresses and strains in ways that are not possible with traditional composite materials composed of single direction tows, or 2D woven composites, sandwich composites or stacked laminate materials.

In materials science, advanced composite materials (ACMs) are materials that are generally characterized by unusually high strength fibres with unusually high stiffness, or modulus of elasticity characteristics, compared to other materials, while bound together by weaker matrices. These are termed "advanced composite materials" in comparison to the composite materials commonly in use such as reinforced concrete, or even concrete itself. The high strength fibers are also low density while occupying a large fraction of the volume.

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.
