Carbon fiber reinforced polymer, is a plastic reinforced with carbon fibers or (CFRP, CRP, CFRTP or often simply carbon fiber, or even carbon), is a very strong and light plastic containing carbon fibers.

CFRPs can be expensive to produce, but are commonly used wherever a high strength-to-weight ratio and stiffness is required, such as aerospace, automotive, civil engineering, sporting goods, and a growing number of other consumer and technical applications.

The binding polymer is often a thermosetting resin such as epoxy, but other thermoplastic or thermoplastic polymers, such as polyester, vinyl ester or nylon, are sometimes used. The composite may contain other fibers, such as an aramid (e.g. Kevlar, Twaron), aluminum, ultra-high molecular weight polyethylene (UHMWPE) or glass fibers, as well as carbon fiber. The properties of the final CFRP product can also be affected by the type of additives introduced into the bonding matrix (the resin). The most common additive is silica, but other additives such as rubber and carbon nanotubes can be used. The material is also known as graphite reinforced polymer or graphite fiber reinforced polymer (GFRP is less common, as it clashes with glass fiber reinforced polymer). In product advertisements, it is sometimes simply referred to as the graphite fiber for the short circuit.

The Airbus A350 This was one of the first commercial aircraft to have wing spars made of composites. The Airbus A380 was one of the first commercial airliners to have a CFRP center drawer; It is the first to have a smoothly contoured wing cross section instead of wings that are divided span-wise into sections. This continuous, fluid cross section optimizes aerodynamic efficiency. Additionally, the trailing edge, along with the rear bulkhead, empennage and non-pressurized fuselage are made of CFRP. However, many delays have pushed order delivery dates due to problems with the manufacturing of these parts. Many aircraft using CFRP have experienced delays with delivery dates due to the relatively new processes used to manufacture CFRP components, while metal structures have been studied and used in airframes for years, and the processes are relatively well understood. A recurring problem is the monitoring of structural aging, for which new methods are constantly being investigated, due to the unusual multi-material and anisotropic nature of CFRP.[2]​.
