摘    要:通过对CF/S-157PF复合材料进行氧-乙炔烧蚀试验研究,得到了烧蚀试验中的重要表征参数即有效烧蚀焓,并利用多元线性回归方法,拟合得到了该参数与热流密度和烧蚀时间的数学模型,即Heff=0.016 3·q0.871 5·t0.191 3。经检验,该回归模型适用性较好,预测准确度较高,为复合材料该项性能的评估建立了快速、有效、可靠的试验方法。

关 键 词:复合材料  燃烧    多元回归  数学模型

Abstract:The important characteristic parameter,namely the effective enthalpies of ablation,was obtained by the research on CF/S-157PF composite under oxyacetylene flame test conditions.And using multiple linear regression,the mathematic model between the effective enthalpies of ablation,the two major factors,namely the heat flux density and ablation time is as follows:Heff=0.016 3·q0.871 5·t0.191 3.Being verified,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 rapidly,effectively and accurately in the oxyacetylene flame test.
Keywords:Composite Flame Enthalpy Multiple regression Mathematic model
