Abstract
On the basis of standard data for the density and the initial and final temperatures in the decomposition (pyrolysis) of thermoprotective binder composites, the law describing their decomposition is identified. That law permits determination of the mass of gases generated at the thermal wavefront, which takes the form of a narrow pyrolytic zone. The gases filter through the porous coke residue to the external boundary, and so affect the thermal state of the thermoprotective composite. On the basis of the law derived, the analysis of the composite’s pyrolysis is simplified, because there is no need to take account of the chemical kinetics.
复合材料中的传热和传质与相变引起的热波
摘要 根据热防护粘合剂复合材料分解（热解）过程中的密度、初始温度和最终温度的标准数据，确定了描述其分解的规律。根据这一规律，可以确定在热波前沿产生的气体质量，热波前沿是一个狭窄的热解区。气体通过多孔焦炭残渣过滤到外部边界，从而影响热保护复合材料的热状态。根据推导出的规律，对复合材料热解的分析得以简化，因为无需考虑化学动力学。
