The Addition of Polyethyletie-Polyamine Surface Treated Carbon Nanotube on the Interfacsal Adhesion of Carbon Fiber-Reinforced Polyimide Composite
Carbon fiber reinforced polyimide (CF/PI) composites have been filled with polyethylene-polyamine-treated carbon nanotube to enhance the adhesion. According to the modification, the interlami-nar shear strength (ILSS) of composites has been greatly improved. Dynamic wetting method, XPS and SEM are used to examine the microscopic properties of resultant composites. The enhanced ILSS is attributed to the CNT interlock, which improves the wetting between carbon fibers and resins.
