摘要：
By reasonably designing the comparison model, a new test method for the injection factor of resin matrix composites is proposed. The arc wind tunnel test is carried out for the new resin matrix composites to obtain the wall heat flux density of resin matrix materials with and without pyrolysis gas injection. The ejection factor, which may assess the ejection effect of new resin matrix materials, is generated by examining the ejection effect of resin matrix composites under particular thermal environment circumstances. The results show that: the carbonization rate of quartz phenolic materials is higher than that of quartz hybrid phenolic materials; The ejection factor of quartz phenolic materials is about 0.825. The impact of the ejection effect on the flux of surface heat should be taken into account in practical design. Quartz hybrid phenolic materials have an ejection factor of roughly 1, making it possible to largely overlook the thermal blocking effect brought on by gas pyrolysis. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
