摘　　要：对石英纤维布进行了高温脱蜡处理,并制成了石英布增强氰酸酯树脂基预浸料及其复合材料,对比了脱蜡处理前后预浸料的理化性能和工艺性的变化,以及复合材料介电性能和力学性能的变化。结果表明,脱蜡处理后的石英布/氰酸酯预浸料的工艺性能更好,复合材料的介电性能保持不变,力学性能显著提高,其中弯曲强度提高31%,层间剪切强度提高16%,脱蜡后界面结合更好。Dewaxing of quartz fiber weave was done by surface treatment at high temperature, and quartz/cya- nate ester prepregs as well as the composites were produced. Properties of prepregs and composites, with and without dewaxing, were compared. It was found that the processability of prepregs was improved by dewaxing, the composites＇ dielectric properties remained the same, and the mechanical properties were improved significantly with flexural strength increased by 31% and interlaminar shear strength increased by 16%. The interface adhesion of composites was improved by dewaxing of quartz fibers.
