摘要

双马来酰亚胺树脂(BMPN)基复合材料广泛应用于飞机承重部件。它们在受到冲击后的损伤评估和修复方案一直是民用飞机复合材料研究中的重要问题。为了更好地理解其失效行为,尤其是复合材料层压板固结修复后的失效行为,本文建立了 BMPN 基复合材料的三维有限元模型。通过 ABAQUS 子程序 USDFLD 实现了三维 Hashin 准则和 B-K 准则的构成模型,分别模拟了复合材料层板和粘合层的破坏行为。通过模拟,比较并讨论了修补层的层设置和层属性对修复过程后强度恢复的影响。结果表明,母层压板的失效模式高度依赖于纤维角度,随着粘合剂层强度的增加,通过增加附加层可以显著改善修复后复合材料层压板的恢复效果。

Failure behavior study of repaired bismaleimide resin matrix composite laminates with considering repairing process

Failure behavior study of repaired bismaleimide resin matrix composite laminates with considering repairing process

Bismaleimide resin (BMPN) matrix composites are widely used in aircraft load-bearing components. Their damage assessment and repair schemes after impact are always the important issues in the research of civil aircraft composite. In order to better understand their failure behaviors, especially after the cementing repair of the composite laminates, a three-dimensional finite element model of the BMPN matrix composite was established. The constitutive models of the 3D Hashin criterion and the B-K criterion were implemented through the ABAQUS subroutine USDFLD to simulate the damage behavior of composite laminates and adhesive layers, respectively. Through the simulation the influences of the layer setting of the patch and the layer property on the strength recovery after the repair process were compared and discussed. The results show that the failure mode of the parent laminate highly depends on the fiber angle, and the recovery effect of the repaired composite laminates can be significantly improved by adding additional layers with the increasing adhesive layer strength.
