摘要

With their excellent high-temperature properties and high specific stiffness and strength, metal matrix composites (MMC) find broad applications not only in the aerospace industry, but also in other engineering fields. In this paper, the tensile properties of SiC fiber reinforced pure aluminum, which has potential applications in power transmission systems, were experimentally evaluated in the temperature range from RT to 515 degrees C. Hi-Nicalon tm low-oxygen silicon carbide fibers recently developed by Nippon Carbon were used to unidirectionally reinforce 99.9% pure aluminum (A1090). These specimens had a rectangular or dumbbell shape. The rectangular specimens were used for room temperature testing, in which SiC fibers were aligned in 0 degrees direction, were used for high-temperature testing. Prior to the high-temperature experiments, a 3D FEM analysis was performed to ensure that no unwanted stress concentration existed in the dumbbell specimens.
