Abstract In the current work, the interlaminar fracture behavior of carbon fiber-Al laminates (FML) was investigated in mode I using double cantilever beam (DCB) specimen with a modified sub-layers sequence of Al/[C]02/Al/[C]02. Various microcapsules comprising hollow capsule and core–shell microcapsules were synthesized, and the integration effect of different microcapsules on the interlaminar delamination resistance of FML was inspected. The fracture surfaces of DCB specimens were also researched at micro-scale. The microscopic and FT-IR studies of synthesized microcapsules proved the successful preparation of microcapsules. It was observed that the presence of all types of microcapsules increased both mode I interlaminar fracture initiation (GIC, Ini) and propagation (GIC, Pro) energies of FML by activating crack energy dissipating micro-mechanisms.

空心和核壳微胶囊增强碳纤维铝层压板的层间电阻

摘要 在目前的工作中，碳纤维-铝层压板 (FML) 的层间断裂行为在模式 I 下使用双悬臂梁 (DCB) 试样进行了研究，该试样具有 Al/[C]02/Al/[ C]02。合成了包括空心胶囊和核壳微胶囊的各种微胶囊，并考察了不同微胶囊的整合对FML层间抗分层性的影响。DCB 试样的断裂表面也进行了微观研究。合成微胶囊的显微和 FT-IR 研究证明微胶囊制备成功。据观察，所有类型的微胶囊的存在都增加了 I 型层间断裂起始（GIC，Ini）和扩展（GIC，
