3k plain woven carbon fiber fabric roll

3K 200g T300 carbon fiber fabric

The high modulus of carbon fibers fabric comes from the high crystallinity and the well alignment of crystals in the fiber direction, while the strength of carbon fibers is primarily affected by the defects and crystalline morphologies in fibers . MP carbon fibers usually show higher elastic modulus but lower tensile strength than PAN carbon fibers . The mesophase (liquid crystalline) spinning dopes for MP carbon fibers contain both anisotropic and isotropic phases. The shear force in the spinning process aligns the anisotropic phase to form a well orientated structure with a relatively large crystal size. In contrast, amorphous PAN dope is spun into precursor fibers through solution spinning and the molecular alignment is achieved by the shear in spinning as well as the fiber drawdown in the following processes.
