Experimental Study on Ablative Properties of Carbon/phenolic Composite

总结了电弧加热器湍流导管试验装置上对碳 /酚醛复合材料的烧蚀试验结果 ,利用多元线性回归方法 ,拟合出烧蚀材料的有效烧蚀焓与冷壁热流密度、壁面压力的关联式。在一定热流、压力范围内可以很方便地计算出碳

The ablation test results of carbon/phenolic composites tested in turbulent duct connected to arc heater are generalized. The multiple linear regression method is used to fit out a correlation, which is the tie in equation about effective enthalpy of ablation of composite with the cooled wall heat flux and wall static pressure. With this correlation, the effective enthalpy of ablation and mass loss rate of carbon/phenolic composites can be calculated conveniently in a certain range of heat rate and wall static pressure.
