| 摘要: |
| 为得到不同温度下石英杂化酚醛材料的渗透率,自主搭建了材料气体渗透率测试平台,提出基于Darcy定律的复合材料气体渗透率的测试方法。对不同温度下石英杂化材料进行研究,测量渗透过程中试验件上下表面气体压力变化和流过试验件的气体流量,进而得到复合材料的渗透率。结果表明:该实验平台可以用来测量复杂孔隙复合材料的渗透率。石英杂化酚醛材料渗透率与热解温度呈正相关,热解温度越高,复合材料的渗透率越大,材料渗透率和热解温度满足关系式K=9.5×10-15T-6.32×10-12。673 K热解温度下,复合材料渗透率为10-13 m2量级；873 K和1 073 K热解温度下,其渗透率在10-12 m2量级。本试验结果丰富了该类树脂基复合材料的基础物性数据,为材料渗透和热质扩散特性分析提供了依据。 |

| Abstract: |
| In order to acquire the permeability of quartz hybrid phenolic materials at different temperatures, the experimental device which was used for measurement in gas permeation process in quartz hybrid phenolic materials was developed, and a method based on Darcy′s law for measuring permeability of quartz hybrid phenolic materials was presented. Quartz hybrid phenolic materials at different pyrolysis temperatures were chosen as the research object, and the gas pressure between down and upper materials and the gas flow rate through 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. As the results show, the permeability of the quartz hybrid phenolic material is positively correlated with the pyrolysis temperature. The higher the pyrolysis temperature is, the greater the permeability be. The permeability level is in 10-13 m2 at 673 K pyrolysis temperature and in 10-12 m2 at 873 K and 1 073 K pyrolysis temperature. Furthermore, permeability of quartz hybrid phenolic materials and pyrolysis temperature meet the formula K=9.5×10-15T-6.32×10-12. The experimental results have enriched the basic physical data of this kind of resin-based composite materials, and provided a basis for the analysis of material permeability and thermal mass diffusion characteristics. |
