A review of the effect of loading rate on the mechanical properties of unidirectional carbon fibre reinforced polymer composites

A comprehensive literature review on the loading rate dependent behaviour of unidirectional (UD) carbon-fibre-reinforced polymer (CFRP) composites has been carried out with the aim to identify common trends and highlight key areas for future research. Starting with the micro-scale constituents, literature data on the effect of loading rate on elastic stiffness, strength, and fracture properties have been collected and compared. While carbon fibres showed no significant rate effects, the rate dependency of the strength and stiffness properties was found to be consistent across various polymer matrix materials. In contrast, there was a general lack of consensus on the rate dependency of the matrix fracture properties.

At the macroscopic scale, the effects of loading rate on the composite strength and stiffness properties were, again, found to remain consistent across different combinations of fibre and matrix materials, while conflicting reports have been found on the rate dependency of the fracture properties. Finally, it has been shown that the rate dependency of composite strength and stiffness properties can be related to the properties of the constituents through well-established micromechanics-based homogenisation theories and failure criteria.

《关于单向碳纤维增强聚合物复合材料加载速率对机械性能影响的研究综述》

为探究普遍趋势并凸显未来研究的关键领域，已对单向（UD）碳纤维增强聚合物（CFRP）复合材料的加载速率依赖行为进行了全面的文献综述。从微观尺度的组成成分出发，收集并比较了关于加载速率对弹性刚度、强度和断裂性能影响的相关文献数据。尽管碳纤维表现出无显著速率效应，但强度和刚度性能的速率依赖性在多种聚合物基体材料中表现出一致性。相反，在基体断裂性能的速率依赖性方面，普遍缺乏共识。

在宏观尺度上，复合材料的强度和刚度性能对加载速率的影响在不同纤维和基体材料的组合中再次表现出一致性，而在断裂性能的速率依赖性方面，则出现了相互矛盾的报告。最后，研究表明，复合材料的强度和刚度性能的速率依赖性可以通过基于微机械学的均质化理论和失效准则与组成成分的性质相关联。
