模拟碳纤维增强复合材料的纵向压缩破坏已经尝试了几十年。尽管有许多发展，没有一个单一的模型已经浮出水面，同时提供一个明确的解释微观力学的失败，以及验证预测的一般应力状态。本文通过提供实验数据（包括在传播过程中加载扭结带的扫描电子显微镜观察，以及与纤维成45°角的脆性剪切断裂）和回顾先前提出的微观力学分析和数值模型，探讨了其原因。本文主要集中在原始单向（UD）复合材料，但编织和回收复合材料的研究也提出，突出这些情况下的相似性和差异。据发现，虽然扭结带形成（也被称为在文献中作为微屈曲）是主要的UD复合材料在纵向压缩下，另一种故障模式相关的纤维的故障可以观察到实验。它还表明，在UD复合材料中观察到的故障过程的微观力学是类似于在其他纤维架构，因此鼓励适应和应用模型开发的前者到后者。
Modelling the longitudinal compressive failure of carbon-fibre-reinforced composites has been attempted for decades. Despite many developments, no single model has surfaced to provide simultaneously a definitive explanation for the micromechanics of failure as well as validated predictions for a generic stress state. This paper explores the reasons for this, by presenting experimental data (including scanning electron microscopic observations of loaded kink bands during propagation, and brittle shear fracture at 45°to the fibres) and reviewing previously proposed micromechanical analytical and numerical models. The paper focuses mainly on virgin unidirectional (UD) composites, but studies for woven and recycled composites are also presented, highlighting similarities and differences between these cases. It is found that, while kink-band formation (also referred to in the literature as microbuckling) is predominant in UD composites under longitudinal compression, another failure mode related to the failure of the fibres can be observed experimentally. It is also shown that the micromechanics of the failure process observed in UD composites is similar to that in other fibre architectures, hence encouraging the adaptation and application of models developed for the former to the latter.
