摘要
研究了石英玻纤布增强BMP350聚酰亚胺树脂基复合材料的热物理性能、力学性能和介电性能,结果表明石英玻纤布/BMP350复合材料具有稳定的热物理性能、优良的综合力学性能和优良的电性能,可在320℃下使用。尤其是石英玻纤布/BMP350复合材料的介电性能具有极好的频率稳定性,适合作为高透波材料。
The thermophysical properties, mechanical properties and dielectric property of polyimide matrix composites reinforced by quartz fibre cyanate are studied in this paper. The results show that the quartz fibre cyanate/BMP350 composites has good mechanical properties and excellent dielectric property, and the operating temperature of the composites is under 320℃. Especially, since its dielectric property seems to have excellent stability to frequency, the quartz fibre cyanate/BMP350 composites could be used as high transmission material.
