Carbon Fiber Reinforced Polymer

Definition

Carbon fiber reinforced polymer (CFRP) is a composite material consisting of a polymer matrix reinforced with carbon fibers, known for its high strength-to-weight ratio and exceptional stiffness. This combination results in materials that are lighter and stronger than metals, making CFRP an attractive choice in various applications including aerospace, automotive, and sporting goods. The advanced properties of CFRP arise from the unique characteristics of both carbon fibers and the polymer matrix, allowing for superior performance in demanding environments.
