Pseudo-ductility presents a potential means for preventing catastrophic failure in composite materials; large deformations will prevent brittle fracture and provide warning before final failure. This work explores how the pseudo-ductility and strength of aligned hybrid discontinuous composites can be controlled by manipulating the arrangement of different fibre types. Aligned carbon/glass hybrid specimens with different fibre arrangements are manufactured and tested using a modification to the High Performance Discontinuous Fibre (HiPerDiF) method. Experimental results are complemented by an improved virtual testing framework, which accurately captures the fracture behaviour of a range of hybrid discontinuous composite microstructures. With a randomly intermingled fibre arrangement as a baseline, a $27\%$ increase in strength and a $44\%$ increase in pseudo-ductility can be achieved when low elongation fibres are completely isolated from one-another. Results demonstrate that the HiPerDiF method is the current state-of-the-art for maximising the degree of intermingling and hence the pseudo-ductility of hybrid composites.

假延展性是防止复合材料灾难性故障的一种潜在手段。大的变形将防止脆性断裂，并在最终失效之前发出警告。这项工作探索了如何通过操纵不同纤维类型的排列来控制取向的混合不连续复合材料的拟延性和强度。使用改进的高性能不连续纤维（HiPerDiF）方法制造并测试了具有不同纤维排列的对齐碳/玻璃杂化样品。实验结果得到改进的虚拟测试框架的补充，该框架可以准确地捕获一系列混合不连续复合微结构的断裂行为。以随机混合的光纤排列为基准，$27％$ 增加力量和 $44％$当低伸长率的纤维彼此完全隔离时，可以提高假延展性。结果表明，HiPerDiF方法是目前用于最大程度地提高混合程度并因此最大程度提高混合复合材料的假延展性的技术。
