摘　　要：为充分利用石英纱线及其纤维毡良好的隔热效果制备隔热性能优异的石英纱线/石英纤维毡三维织物,采用石英纱线和纤维毡在小样织机上进行三维立体编织,针对石英纱线/石英纤维毡三维织物不易编织等诸多问题,对织机综丝综框进行降低摩擦处理;然后采用控制变量法和实验对比法,对所得石英纱线/石英纤维毡三维织物在热环境下的隔热性能进行测试表征,对其加热状态下的温度和外观形状的变化趋势和规律进行探讨。实验结果表明:石英纱线/石英纤维毡三维织物在300~700℃时,平均隔热保留率是相等厚度普通石英纤维织物的4倍,验证了石英纱线/石英纤维毡三维织物的优越隔热性能。确定了石英纱线/石英纤维毡三维织物具有良好的整体性能和隔热性,能够作为航天飞行器的外部隔热材料抵挡高温冲刷,因此对石英纱线/石英纤维毡三维织物性能的研究具有深远意义。Objective Quartz fibers and their fiber mats are known for their high temperature resistance,strength and insulation and are widely used in the aerospace industry.However,how to composite quartz fibers and their fiber mats to give them the integrity and washout resistance of aerospace materials.Therefore,we performed composite weaving using an integrated weaving method and investigated the thermal insulation properties of quartz/fiber mats three-dimensional spacer fabrics.This study aims to provide valuable insights into the weaving of quartz fibers and the overall structural thermal insulation properties of three-dimensional fabrics.Method Quartz/fiber felt three-dimensional fabrics,quartz yarn and fiber felt with better thermal insulation properties using a one-piece knitting method for knitting,fabric thickness instrument to measure the quartz/fiber felt three-dimensional spacing fabrics,calculating the number of single-layer quartz fiber fabrics of equal thickness,placing the fabric on the top of the heating plate,the sensor to measure the temperature of the fabric's upper and lower surfaces,calculating the rate of retention of the thermal insulation.Results According to the variation of the fabric thermal insulation performance,the thermal insulation performance of quartz/fiber mat 3-D spacer fabrics is much higher than that of quartz fiber fabrics of the same thickness.By comparing thermal insulation retention of ordinary quartz fiber fabrics with quartz/fiber mat 3-D fabrics.Quartz/fiber felt three-dimensional fabrics of thermal insulation performance is significantly better than the same thickness of ordinary quartz fiber fabrics,spacer fabrics of thermal insulation temperature retention rate of up to 300℃,the retention rate of 64.3%is ordinary quartz fabrics insulation effect of 4.14 times,so it shows that the quartz/fiber felt three-dimensional spacer fabrics can be better applied to the application of heat-insulating materials.Conclusion The following conclusions were drawn from the experiments.The q
