Ultrasound for Fiber Fragmentation Size Determination to Characterize Load Transfer Behavior of Matrix-Fiber Interface in Metal Matrix Composites

摘要

It is generally believed that the properties of a composite are significantly affected by the nature of the interface between reinforcement and matrix. The interfacial shear properties of continuous fiber reinforced intermetallic matrix composites (IMC) and metal matrix composites (MMC) are the focus of recent investigations which have employed a number of experimental techniques including fiber pull out, fiber push out, and fiber fragmentation tests. Published works on fiber fragmentation tests of MMC include testing of the following composite systems: W/Cu [1,2], SiC/Al 1100 and SiC/Al 6061 [3], SiC/Ti-6A1-4V [4,5], and B/Ti-6A1-4V [5].
