Abstract
Polyimide-based composites have been widely used as structural materials in aerospace and automotive industries. In the present work, carbon fiber fabric reinforced polyimide composites (CF/PI) were modified by carbon nanotubes (CNTs). The monotonic bending properties and bending fatigue performance of CNTs modified CF/PI were investigated at room temperature. Both bending strength and bending modulus of CF/PI can be increased by CNTs. The CNTs filler could inhibit crack initiation and retard crack propagation. The fatigue resistance is significantly enhanced in CNTs modified CF/PI, which is related to the CNTs enhanced matrix crack resistance and fiber/matrix debonding.
