| Research Abstract |
The tensile properties and fracture behavior of polyimide composite bundles incorporating carbon nanotubes grafted (CNT-grafted) high-tensile-strength polyacrylonitrile (PAN)-based (T1000GB) and high-modulus pitch-based (K13D) carbon fibers were investigated. The CNT were grown on the surface of the carbon fibers by chemical vapor deposition. The results clearly demonstrate that CNT grafting was effective for improving the Weibull modulus of T1000GB PAN-based and K13D pitch-based carbon fiber bundle composites. In addition, the average tensile strength of the CNT-grafted T1000GB and K13D carbon fiber bundle composites was similar to that of the as-received carbon fiber bundle composites.
