摘要/Abstract

摘要： 为了获得不同热解温度下酚醛树脂复合材料渗透率，设计搭建了复合材料气体渗透过程实验测量装置，提出了一种测量复合材料渗透率的方法，基于达西定律获得了复合材料渗透率。以不同热解温度下酚醛树脂复合材料为研究对象，进行了气体渗透过程实验测量，获得了材料上下表面气体压力变化曲线，同时得到了渗透过材料的气体流量，进而通过达西定律得出材料的渗透率。结果表明，该实验装置能够实现复杂孔隙复合材料的渗透率的测量。整体上，热解温度越高，渗透率越大。热解温度为400℃，渗透率量级在10^-13；600℃和800℃时，渗透率量级在10^-11。材料渗透率K和热解温度T满足K=9.7×10^-14T-4×10^-11。该实验结果为该类材料的渗透和热质扩散性能分析提供了基础物性数据。

Abstract: To acquire the permeability of phenolic composites under different pyrolysis temperatures, the experimental device which was used for the measurement in gas permeation process in phenolic composites was developed, and a method for measuring permeability of phenolic composites was presented. The formula for calculating permeability was derived based on Darcy's law. Phenolic composites under different pyrolysis temperatures were chosen as the research object. Though experiment measurement, the gas pressure between down and upper materials and the gas flow penetrating the materials were obtained. The permeability of the materials was obtained according to Darcy's law. The results show that the permeability of complex pore composites can be measured by this experimental device. Overall, the higher the pyrolysis temperature is, the greater the permeability is. The permeability level is in 10^-13 at 400℃ pyrolysis temperature, and in 10^-11 at 600℃ and 800℃ pyrolysis temperature. Furthermore, permeability of phenolic composites K and pyrolysis temperature T meet the formula K=9.7×10^-14T-4×10^-11.The experimental results can provide basic property data for the theoretical analysis on permeability and heat and mass diffusion performance.
