| Summary: | Epoxy–glass fiber–aluminium composite may be of interest for energy absorption
application due to their improved crashworthiness. In the current study, the hybrid–composite
columnar tube specimen has been fabricated by a hand lay–up method using epoxy–glass fiber with
aluminium columnar tube as a core material. An experimental quasi–static crush test has been
performed on the specimen under axial loading. The post–crushing of composite lay–up configuration
was observed during and after interaction of the axial loading with the specimen. The result of crush
morphology analysis on final mode of failure of the specimen was carried out using SEM and showed
combination of several failure modes such as matrix–fiber interfacial fracture, fiber breakage and
hackles. However, the main failure mode is brittle type fracture comprising transverse shearing and
splaying modes. |
