摘要
本文综合叙述了碳纤维增强复合材料接头的设计、成型工艺、强度分析、试验方法及其研究进展,重点介绍了碳纤维增强复合材料耳片接头的尺寸设计、铺层设计和承载设计,以模压法和三维编织法为例介绍了耳片接头的工艺流程,对用于接头强度分析的有限元法、解析法及其相关的强度理论进行了叙述,探讨了复合材料接头拉伸、弯曲和剪切的试验方法,指出了接头设计和试验中存在的问题和今后的研究方向。研究表明,碳纤维增强复合材料接头一般优先选择增强型层压式结构形式,三维编织呈厚度方向增强结构以及关于接头疲劳的研究是今后研究和发展的方向。
The design, the manufacturing craft, the strength analysis, the method of experiment and the research progress of the carbon fiber reinforced composite joints were presented in this paper. The design of size, ply-up and loaded performance for the lug connector were introduced particularly. The flow of craft was also introduced by the example of moulding-press craft and three dimensions weave process. The finite element technology, analytic method and strength theory used in strength analysis of composite joint were presented in this paper. The method of tension, bend and shear experiment were discussed. The problem in the design and experiment of the composite joint were indicated. The research indicated that three dimensions weaving strengthened through the thickness direction and the fatigue of composite joint should be researched and developed.
