Influence of Interfacial Property on Failure Mode of Unilateralism Carbon Fiber Reinforced Resin Matrix Composite Subject to Short-Beam Shear
Abstract:
This study investigates the influence of interfacial property on the failure mode and damage mechanism of carbon fiber composites subject to shot-beam shear. Carbon fiber CCF300 made in China and T300 made in Japan were tested under the condition of 23 degree centigrade dry. Comparison was made for these composites on the shear strength data and the appearance of macro characters. Possible sequence of failure initiation and propagation of each composite was proposed by the SEM with optical microscopy observations of failed specimens. The result revealed that the interfacial property is the most important factor responsible for the failure mode of unilateralism carbon fiber composites, and the Chinese carbon fiber composites need to improve the interfacial property for wider use.
