| 摘 要： | 通过拉伸和剪切试验,研究了3种不同的树脂转型模型(RTM)成型工艺(即RTM、引入缝纫的RTM和共胶接)对复合材料十字型接头力学性能的影响。根据实验现象,分析和讨论了其破坏机理。实验结果表明,3种工艺中,RTM成型的十字型接头力学性能最优,胶接和缝纫工艺都会对接头的强度产生不同程度的影响。通过有限元分析,数值模拟了RTM十字型接头的破坏过程,与实验现象吻合良好。

| Abstract: | Tension and shear tests are carried out on composite cross-joints, produced by resin transfer moulding (RTM), stitch-RTM and cobonding techniques separately, to investigate the influences of different production methods on their mechanical properties and their failure mechanism. It is concluded from test results that, in terms of mechanical properties, the RTM-made cross-joint holds superiority over other two, and both stitch-RTM and cobonding methods have significant adverse effects on mechanical proper- t... |
