摘要：A novel silane coupling agent containing terminal-alkyne and aromatic amid acid groups(WS) for the first time. Then the silane coupling agent containing imide-ring was obtained through ring-closing reaction, which was undergoing by chemical method. The influence of factors including processing temperature and post processing method on the preparation of the coupling agent were studied. Some process factors including the treatment time, the concentration, the pH of the solution with our silane coupling agent(WS) and the fiber surface condition were investigated. The composite was heated in a vacuum oven at 65. for 2 h; a thermal treatment followed at 170 degrees C, 210. for 2 h and 250 degrees C for 4 h. It was showed that with the pretreatment method, 1.5 wt% WS added to react with the QF for 60 min, the Interlaminar Shear Strength(ILSS) of the composites improved about 43.6 %. However, the flexual strength was increased by 60.6 % with 3.5 wt% WS added to react with the QF. So far we have preliminary researched the mechanical properties of composite materials, depth discussion in toughening is still under exploration. The composites fracture morphologies were observed by SEM, which were treated by coupling agent(WS) or not.
