The Mechanical Properties of Improved Non-Coating C/A1 Precursor Wires Fabricated by Ultrasonic Liquid Infiltration Method

摘要

The ultrasonic liquid infiltration method developed to produce C/A1 precursor wires were carried out early in 1991. However, the tensile strength of the precursor wires was rather low. Precursor wires with good properties were obtained by improving process parameters including preheated temperature of fibers, infiltrating time, etc. In this paper, the process parameters and corresponding properties of composites were specified in details.
