N2 - This study is concerned with the effects of the fiber content on the macroscopic and macroscopic fracture mode of unidirectional carbon/epoxy composite. Necked-on-thickness specimens having a fiber volume fraction (Vf) ranging from 30 to 70% were tested in tension in the fiber direction. The effects of the fiber volume fraction on the fracture appearance were then examined. The results show that a transition in fracture mode occurred, from tensile fracture at the necked region at low Vf to interlaminar shear failure at high Vf. Fracture-mode transition also occurs at the microscopic level. Examination of SEM photomicrograph of the specimen surface shows that, at low Vf, the specimen fractured in fiber-break dominated fracture, whilst, at high Vf, interfacial-damage dominated fracture was observed. An analysis to determine the conditions for the occurrence of each fracture mode is presented.
