Influence of Fiber Property Variation on Composite Failure Mechanisms

Source

This paper deals with the energy released when a fiber fails, and the local mechanisms available for energy absorption. This process is examined analytically for a linear elastic material, and the advantage of a controlled interfacial failure process is clearly indicated. Experimental observations of individual carbon fibers, having similar strain energy densities but different interfacial response, are presented. Gross fracture of tension specimens containing high fiber content is shown to correlate well with observations of individual fiber failure mechanisms. Conclusions are presented based on the analysis and experimental results.
