Abstract
In this paper, the important characteristic parameter, namely the mass loss rate, was obtained by the investigating on CF/S-157PF composite under oxyacetylene flame test conditions. And using multiple linear regression , the mathematic model on the mass loss rate and the two major factors, namely the heat flux density and ablation time is as follows; M = 0. 043 · q0.128 · t-0.191 . It is verified that, the regression model is very applicable and the forecast accuracy is much better. So the erosion properties of CF/S-157PF composite can be evaluated with this rapid, effective, and accurate method in the oxyacetylene flame test.关键词
