摘要/Abstract

摘要： 在大型结构件的低成本制造工艺中,织物体系的拼接缝具有不可避免性,拼接缝的交替处理方案直接影响到最终产品的结构性能。本文提出了三种不同结构形式的拼接方案,通过真空辅助成型工艺,对S玻纤缎纹织物进行层合板厚度、拼接缝方案、拼接缝距离的正交试验,测试对应试样的拉伸性能,归纳总结不同拼接参数对层合板力学性能的影响。通过有限元软件,建立单层结构和层间弹性结构的有限元模型,并进行拉伸性能计算,为复合材料构件铺层设计提供参考。

Abstract: In the low cost manufacturing process of large structural parts, the splicing seam of fabric system is unavoidable. The staggered processing scheme of splicing seam directly affects the structural performance of fabric products. In this paper, three kinds of splicing schemes of different structure forms are put forward, and the orthogonal test of the thickness, splicing seam scheme and splicing seam distance of S-glass satin fabric is carried out by vacuum-assisted forming technology. The tensile properties of corresponding samples are tested, and the effects of different splicing parameters on the mechanical properties of the laminates are summarized. The finite element models of single-layer structure and interlaminar elastic structure are established by finite element simulation, and the tensile properties are calculated, which can provide reference for the lamination design of composite components.

Key words: laminate, fabric joint, mechanical property
