Abstract A micromechanical study is carried out taking the initial expected damage that is manifested in a composite laminate by the debonding between the fibres and matrix in the 90° lamina as a reference. Questions such as the influence in the appearance of damage of the inter-fibre distance and the orientation of the fibres with respect to the loading direction are studied. Additionally, the effect of the presence of damage at a secondary fibre in the subsequent appearance of further debonding is also analysed. Finally, the conclusions reached are supported by experimental evidence obtained by testing [0,90n]S laminates.

复合材料横向损伤中纤维间的相互作用
摘要 以复合材料层合板中纤维与基体在90°层间脱粘所表现出的初始预期损伤为参考,进行了微观力学研究。研究了诸如纤维间距离和纤维相对于加载方向的取向对损伤外观的影响等问题。此外,还分析了在后续出现进一步脱粘的情况下,在二次纤维处存在损坏的影响。最后,得出的结论得到了通过测试 [0,90n] S 层压板获得的实验证据的支持。
