CFRP stands for carbon fiber reinforced polymer matrix composites.

Carbon fiber has higher performance than glass fiber. The tensile strength of carbon fiber reinforced polymer matrix composites is higher than that of glass fiber. Its elastic modulus is 4 to 6 times that of glass fiber, and its strength and elasticity are at a high temperature of 2000 degrees Celsius. The modulus remains basically unchanged, and the low overflow below 180 degrees Celsius does not become brittle. In addition, its specific strength and specific modulus are the highest among all heat-resistant fibers, so carbon fiber is an ideal reinforcing phase, so carbon fiber reinforced polymer. CFRP is the most widely used material. 

CFRP has lower density and higher specific strength and specific modulus than FRP. Its specific strength is 5 to 6 times that of high-strength steel and titanium alloy, and 2 times that of FRP. The specific modulus is 3 to 4 times that of these materials. Therefore, CFRP is used in the aerospace industry, such as the space shuttle payload door, auxiliary beam, vertical tail, active landing gear door, internal pressure vessel, etc., reducing the space shuttle by up to 2t. In addition, CFRP is also used in the large-scale structural trusses and solar cell supports of the space station. In addition, CFRP is widely used in the aviation industry, such as aircraft main wing shells, rear wings, horizontal and vertical tails, spoilers, elevators, internal and external ailerons, etc. In addition, CFRP is also used for some products that require lighter, stronger and better rigidity than FRP, such as tennis rackets, golf clubs, fishing rods, racing car bodies, etc. in sporting goods.
