在本文中，我们证明了一种新的混合复合材料的铝和碳纤维增强聚合物（CFRP）的微观结构的启发，生物交叉层状微观结构是一个有吸引力的替代应用程序的结构完整性是至关重要的。具有这种微观结构的复合材料原型和测试使用标准和薄层CFRP预浸料。三点弯曲试验在SEM环境中进行，显示广泛的扩散损伤的CFRP和屈服的铝。这是第一个混合交叉层状启发微观结构在文献中，结果表明，这种新的微观结构可以加载到记录大曲率（与其他CFRP和混合CFRP相比），同时保持其结构完整性和稳定条件下的能量耗散。
In this paper, we demonstrate that a novel hybrid composite of aluminium and Carbon Fibre Reinforced Polymer (CFRP) with a microstructure inspired by a biological crossed-lamellar microstructure is an attractive alternative for applications where structural integrity is paramount. Composites with such microstructure are prototyped and tested using both standard and thin-ply CFRP prepreg. Three-point bend tests are carried out in an SEM environment, showing extensive diffuse damage in the CFRP and yielding in the aluminium. This is the first hybrid crossed-lamellar-inspired microstructure in the literature and the results demonstrate that this novel microstructure can be loaded up to record large curvatures (in comparison with other CFRPs and hybrid CFRPs) while retaining its structural integrity and dissipating energy under stable conditions.
