Abstract

Two of the critical factors controlling the long-term performance and durability of composites in structural applications is the fiber-matrix interfacial shear strength (IFSS) and the durability of the fiber-matrix interface. The single fiber fragmentation test (SFFT) has been viewed by many as the best method for determining these parameters. Although the SFFT has been extensively researched, the micro-mechanics models used to obtain IFSS values are based on simplifying assumptions that are usually not realized under experimental conditions. Thus, results from this test often violate the known strength of the constituent materials. Therefore, a new test method is presented here that utilizes realistic assumptions.
