| Summary: | Epoxy-matrix composites reinforced by CCF800H, the domestic high strength intermediate modulus carbon fiber, were prepared. Thermoplastic resin was used as the toughening agent of the resin. Through regulating the content of toughening particle in the epoxy resin,effects of the content of toughening agent on the mode-Ⅱ interlaminar fracture toughness of the composite were investigated. The results show that the thermoplastic toughening particles gather at the interlayers of the composite with the filtering effect of the carbon fibers on those particles. The interlayers get thicker with the increasing of the toughening agent. The mode-Ⅱ interlaminar fracture toughness of the composite is increased under the concurrent actions of the toughness and thickness of the interlayer resin. |
