Carbon fibre reinforced plastic is lightweight and strong
Carbon fibre reinforced plastic, also known as carbon fibre reinforced polymer (CFRP), is a composite material made of carbon fibres and resin, usually epoxy resin. The carbon fibres are woven into a fabric or mat and then impregnated with the polymer resin. This combination of materials results in a high-strength, lightweight material.
CFRP is a highly versatile and advanced material with a wide range of applications. Its strength and stiffness make it ideal for use in aerospace, automotive, civil engineering, and construction. For example, in aerospace, CFRP is used to make aircraft parts such as wings, fuselages, and rotor blades. In the automotive industry, it is used for body panels, frames, and suspension components. CFRP is also used to reinforce concrete, steel, and timber structures in construction, enhancing their load-bearing capacity.
The lightweight property of CFRP is a significant advantage, reducing fuel consumption and improving performance in aircraft and automobiles. Additionally, its high strength-to-weight ratio makes it valuable in applications where high strength is required without adding unnecessary weight. CFRP is up to five times lighter than steel and has only about 60% of the weight of aluminium.
CFRP also exhibits excellent corrosion resistance, making it suitable for use in various environments. The carbon fibres themselves are not affected by moisture, although the moisture can plasticize the polymer matrix, altering some of its properties. Overall, CFRP's combination of strength, stiffness, and corrosion resistance makes it a popular choice in many industries.

It is used in aerospace, automotive and construction
Carbon fibre reinforced plastic, also known as carbon fibre or carbon composite, is a strong and lightweight fibre-reinforced plastic that contains carbon fibres. It is commonly used in applications that require high strength-to-weight ratios and stiffness, such as in the aerospace, automotive, and construction industries.
Aerospace
In the aerospace industry, carbon fibre reinforced plastics (CFRPs) are used where high strength-to-weight ratios and stiffness are required. CFRPs are composite materials that consist of two parts: a matrix and a reinforcement. The reinforcement, carbon fibre, provides strength and rigidity to the composite, while the matrix, typically a thermosetting plastic like polyester resin, binds the reinforcements together. The epoxy matrix used for engine fan blades, for example, is designed to be impervious to jet fuel, lubrication, and rainwater. CFRPs are also used in aerospace due to their excellent corrosion resistance.
Automotive
In the automotive industry, CFRPs have been extensively used in the manufacture of supercars, with some manufacturers using them for monocoque chassis and other components. Low-volume manufacturers have adopted CFRPs for creating body panels for high-end cars due to their increased strength and decreased weight compared to glass-reinforced polymers. Additionally, chopped reclaimed carbon fibre can be used in consumer electronics, such as laptops, providing excellent reinforcement of the polymers used.
Construction
CFRPs have been studied for their potential benefits in construction and have proven to be cost-effective in field applications for strengthening concrete, masonry, steel, cast iron, and timber structures. However, CFRPs are more costly than commonly used alternatives in the construction industry, such as glass fibre-reinforced polymers (GFRPs) and aramid fibre-reinforced polymers (AFRPs). Long-term durability concerns and the brittle nature of CFRPs compared to the ductility of steel have led to hesitancy among engineers to adopt these alternative materials.

It is made of carbon fibres and a polymer resin
Carbon fibre reinforced plastic (CFRP) is a composite material made of carbon fibres and a polymer resin. The carbon fibres are woven into a fabric or mat, which is then impregnated with the polymer resin to form a composite. This composite is then cured at high temperatures and pressures to form a solid material.
The carbon fibres provide strength and stiffness to the composite, while the polymer resin acts as a binder that holds the fibres together. The polymer resin is usually a thermosetting plastic, such as epoxy, polyester, or vinyl ester. However, other thermoset or thermoplastic polymers, such as nylon, can also be used. The specific choice of polymer resin depends on the desired properties of the final product.
The production of CFRP involves several steps, starting with the carbon fibres. These fibres are industrially produced and refined to consist almost exclusively of carbon. They are then woven or laid into a carbon fibre textile using processes similar to those in the textile industry.
The resulting fabric or mat is then impregnated with the polymer resin to form the composite. This composite is then cured and formed into the desired shape, which can be done using a mould or a filament winder. The final CFRP product has a high strength-to-weight ratio and is corrosion-resistant, making it ideal for applications where high strength and low weight are required.
