The impact resistance of fibre-reinforced composites is vital in many applications, and can be improved by exploiting synergies in fibre-hybridisation. These effects are however not sufficiently well understood in the literature. Penetration impact tests were hence performed on carbon/glass hybrids, and the results were linked to the flexural behaviour and translaminar fracture toughness. The results revealed large synergetic effects of up to 40% compared to the linear rule-of-mixtures. The results are also the first to reveal that creating a translaminar fracture surface can strongly contribute to the energy absorbed during penetration impact: 56% for an all-carbon fibre composite and 13% for an all-glass fibre composite. These results prove that strategies for maximising the translaminar fracture toughness can also be exploited to maximise the penetration impact resistance of fibre-hybrids. In carbon fibre composites in particular, ply blocking, using larger yarns and introducing micro-cuts should therefore increase the penetration impact resistance.

纤维增强复合材料的抗冲击性在许多应用中至关重要，可以通过在纤维杂交中发挥协同作用来提高抗冲击性。然而，这些作用在文献中还没有被很好地理解。因此，对碳/玻璃杂化物进行了渗透冲击试验，其结果与弯曲行为和层间断裂韧性有关。结果表明，与线性混合规则相比，协同效应高达40％。该结果也是第一个揭示出形成跨层断裂表面可以极大地促进穿透力吸收过程中吸收的能量的方法：全碳纤维复合材料为56％，全玻璃纤维复合材料为13％。这些结果证明，也可以利用最大化跨层断裂韧性的策略来最大化纤维混杂物的抗穿透冲击性。因此，特别是在碳纤维复合材料中，使用较大的纱线并进行微切割可以实现板层封闭，从而提高抗穿透性。
