用热分析技术定量检测复合材料烧蚀性能

THE DETERMINATION FOR THE ABLATIVE PERFORMANCE OF COMPOSITES QUANliTATIVELY BY THERMAL ANALYSIS

对复合材料氧乙炔烧蚀试验及其系列热分析试验的结果进行了计算和分析。运用统计理论和方法,证明了热分析性能值和烧蚀率之间存在显著的相关性。建立了两者的若干一元和二元线性回归方程,并论证了方程的可靠性。

Many results of oxyancetylene. ablation experiments and systematic thermal analysis of some composites have been calculated and analyzed in this paper. Using a statistic theory and method ,it is shown that there are notable correlations between the thermal properties and the ablativity ,and thus a set of mono-and bi-linear regression equations are established on the two types of parameters. In addition ,the reliability and correctness of the regression equations are demonstrated .
