Abstract:

A high temperature vacuum furnace for across-ply testing of carbon carbon composites has been installed. This furnace has a double-walled water- jacketed vacuum chamber and is equipped with a 30 kVA variable output transformer, semi-automatic vacuum system, a digital temperature controller programmer, a two-color optical pyrometer, various thermocouples, and a digital data acquisition system. This furnace has been installed on an existing Model 1123 Instron and heating to 2200 C has been accomplished. Graphite toolings have been prepared and across-ply tensile testing to 1700 C have been conducted. Keywords Carboncarbon composites, High temperature, Graphite furnace, Across ply strength.
