摘要
研究了石英纤维织物和氧化铝纤维织物增强磷酸盐复合材料的成型工艺、介电性能及力学性能,并分析了影响力学性能高温稳定性的主要原因,获得了可分别在300℃、700℃下长期稳定使用的石英、氧化铝纤维织物增强磷酸盐透波复合材料,在8 GHz~18 GHz范围内,介电损耗均小于0.015,具有宽频低介电损耗的特点,是一类性能优异的耐高温透波复合材料。
Forming process,dielectric properties and mechanical properties of quartz fiber and alumina fiber reinforced phosphate matrix composites were studied in the paper,and the major reason was analyzed which affected the stability of the mechanical properties at the high temperature.Quartz fiber and alumina fiber reinforced phosphate matrix wave-transmitting composites were prepared,which could be applied stably at the temperatures of 300℃and 700℃separately,whose dielectric loss were less than 0.015 ranging from 8 GHz to 18 GHz.They are a sort of wave-transmitting and high temperature resistance composites,with low dielectric loss in the broadband frequency.
