回收碳纤维复合材料的技术现已成熟，因此一个关键挑战是建立回收产品的应用。本文旨在进一步了解回收复合材料的力学响应，以指导回收工艺的优化，并支持其在非关键结构部件中的使用。这项工作彻底的特点三个回收复合材料和分析纤维和界面性能，增强结构，宏观力学响应之间的关系。回收复合材料的结构和其断裂韧性之间建立了明确的关系;这证明了纤维束不一定是回收缺陷，但实际上可以使材料至少增韧一个数量级，而不会显着降低刚度或强度。
Technologies for recycling carbon–fibre composites are now becoming mature, so a key challenge is to establish applications for the recycled products. This paper aims to further our understanding on the mechanical response of recycled composites, so as to guide the optimisation of recycling processes and support their use in non-critical structural components. This work thoroughly characterises three recycled composites and analyses the relations between fibre and interfacial properties, reinforcement architecture, and macroscopic mechanical response. An unequivocal relationship between the architecture of a recycled composite and its fracture toughness is established; this proves that fibre bundles are not necessarily a recycling defect, but can actually toughen the material by at least up to an order of magnitude without significantly reducing stiffness or strength.
