摘要/Abstract

摘要： 胶接接头是复合材料结构中的薄弱位置之一,受到横向冲击时易产生损伤,严重影响其连接强度。本文提出了一种新型页型胶接接头,采用有限元仿真和试验测试的方法,研究了该接头的横向冲击损伤和剩余强度。通过对不同冲击能量、不同搭接长度以及与单搭接胶接接头的对比研究发现:页型胶接接头的剩余强度系数随着冲击能量的增加而降低;随着搭接长度的增加,页型胶接接头的冲击后剩余强度系数提升明显;页型胶接接头的剩余强度能达到同尺寸单搭接接头的4倍以上,具备优越的抗冲击性能。

Abstract: Adhesive joints are among the most vulnerable regions in composite material structures, particularly susceptible to damage under lateral impacts, which significantly affects their connection strength. This study proposes a novel page-type adhesive joint (PTAJ) and investigates its transverse impact damage and residual strength through finite element simulation and experimental testing. The findings demonstrate that the post-impact residual strength coefficient of the PTAJ exhibits a decreasing trend with increasing impact energy. Notably, the residual strength coefficient significantly improves with an increase in lap length. Furthermore, the PTAJ achieves a residual strength exceeding four times that of a single-lap adhesive joint of comparable dimensions, thereby showcasing its superior impact resistance characteristics and engineering potential.
