纤维结构的压缩破坏机制后的影响进行了研究，为广泛的纤维复合材料。对由T800碳纤维-924 C环氧树脂层压板、AS 4碳纤维-PEEK层压板、2D编织T800碳纤维-924环氧树脂和3D编织AS 4碳纤维-LY 564环氧树脂制成的有缺口和无缺口试样进行压缩剩余。此外，无缺口和缺口压缩试验进行山毛榉和桦木胶合板。在所有情况下，主要的失效机制是由纤维微屈曲。无限带扭结模型被用来估计无缺口强度和大规模的裂纹桥接分析被用来预测缺口强度。
The effect of fiber architecture upon the compressive failure mechanisms is investigated for a wide range of fiber composites. Compressive rests are performed on both notched and unnotched specimens made from T800 carbon fiber-924C epoxy laminates, AS4 carbon fiber-PEEK laminates, 2D woven T800 carbon fiber-924 epoxy, and 3D woven AS4 carbon fiber-LY564 epoxy. Additionally, unnotched and notched compressive tests are performed on beechwood and birch plywood. In all cases, the dominant failure mechanism is by fiber microbuckling. An infinite band kinking model is used to estimate the unnotched strength and a large-scale crack bridging analysis is used to predict the notched strength.
