T300 T700 Carbon Fiber Filament Yarn For Sale

● Lightweight and high-strength: Its density is usually only 1.7-1.9 g/cm ³, much lower than steel (~7.8 g/cm ³) and aluminum alloy (~2.7 g/cm ³), but it has amazing tensile strength (such as T700 grade can reach 4900 MPa or more, which is several times higher than high-quality high-strength steel) and extremely high specific strength (strength/density) and specific modulus (modulus/density).

● Extremely high rigidity and dimensional stability: The modulus (an indicator of a material's ability to resist deformation) is extremely high (for example, M40J grade can reach 377 GPa), and the coefficient of thermal expansion is extremely low (even negative in some directions), allowing it to maintain excellent dimensional accuracy in temperature changing environments, making it suitable for precision instruments and optical platform structures.

Carbon fiber filament yarn plays an important role in composite materials, significantly enhancing their mechanical properties. By combining continuous long fibers with other materials, high-performance composite materials can be manufactured, which are widely used in aerospace, automotive manufacturing, sports equipment and other fields.
