F500 Carbon Fiber

F500 Carbon Fiber is a high-performance polyacrylonitrile (PAN)-based fiber engineered for applications that demand superior strength, stiffness, and lightweight characteristics. With a tensile strength ranging from 3200 to 5000 MPa and modulus levels exceeding 450 GPa, this fiber delivers excellent mechanical performance while maintaining low density and thermal expansion. It is extensively used in aerospace and automotive industries, where weight savings translate directly into fuel efficiency and structural agility. F500 fibers are also integral to composite reinforcement in bicycles, sporting goods, and next-generation structural components. In advanced composites, these fibers are combined with epoxy, polyester, or polyamide matrices, creating materials that surpass steel in strength and outperform titanium in stiffness. F500’s electrical conductivity and piezoelectric potential further broaden its role in smart materials and sensing systems. As a core material in multifunctional composites, F500 Carbon Fiber accelerates innovation across industries aiming to maximize performance with minimal mass.
