Abstract Scope |
Carbon fiber reinforced polymer (CFRP) composites are highly sought for owed to their exceptional mechanical properties with applications in industries such as automotive, aerospace, medical, and civil engineering. One main limitation in CFRPs, however, is their reparability and maintenance. This study investigates the fabrication and self-healing in vitrimer-based CFRPs. The vitrimers, a group of thermosetting polymers, are known for their ability to exchange their covalent bonds. The vitrimer used here is aromatic thermosetting co-polyester (ATSP). The healing efficiency at different cure cycles of ATSP CFRP samples was investigated via fracture tests and material characterization. Mode I crack initiation fracture toughness of self-healed composites and control composites were measured via double cantilever beam test, with the healing cycle consisting of heating the sample in air at 280oC for 2 hours. Scanning electron microscopy (SEM) and micro-computed tomography (CT) X-ray imaging verified that healed samples closely resembled the as-fabricated ones. |
