新型改性氰酸酯及其复合材料性能

摘要

The processing, heat-resistance and mechanical properties of novel modified cyanate ester ware evaluated in this article. The dielectric property and mechanical properties of cyanate ester matrix composite materials were also studied. The results showed that the cyanate ester adapted to madding prepreg by hot-melt methods because, of its good process. All of the cyanate ester and composite materials had nice mechanical properties and could be used under 180℃. The composite materials are suitable for use as for high performance microwave-transparence materials and high frequency circuit boards.%采用新型催化剂、增韧剂制得了一种改性氰酸酯树脂,对新型改性氰酸酯树脂的工艺性、耐热性、力学性能进行了评价,并对其复合材料的介电、力学性能进行了研究.结果表明新型改性氰酸酯树脂具有良好的工艺性,适合热熔法制备预浸料；树脂及其复合材料的力学及介电性能优良,可在180℃下使用,适合高性能透波材料和高频电路板使用.
