摘要：The triangle-shape carbon fiber reinforced plastics and the round-shape carbon fiber reinforced plastics were manufactured and the effects of carbon fiber shapes on the flexural properties were investigated. The microstructures and the cross-section areas of the round-shape carbon fiber and the triangle-shape carbon were discussed. As a result, it was found that the triangle-shape carbon fiber reinforced plastics showed higher flexural strength and flexural modulus than round-shape carbon fiber reinforced plastics, and the sile strength and tensile modulus did not reduced, which was attributed to that the triangle-shape carbon fiber reinforced plastics had larger interfacial contact area than round-shape ones, and the wider interfacial contact area between reinforcement and matrix that could effectively transfer the applied load. The flexural properties of fiber reinforced plastics were improved due to the stronger interfacial binding force. (C) 2012 Elsevier B.V. All rights reserved.
