TENSILE FRACTURE STRENGTH ANALYSIS OF SPLICED LAMINATE

Abstract

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
