研究了空心玻璃微珠/环氧树脂复合材料制备工艺、配方设计,并对材料的密度、力学性能、表面改性剂、粒径匹配、热性能、介电性能和微观形貌进行了实验研究.结果表明:空心玻璃微珠/环氧树脂复合材料密度在0.28~0.8g/cm3之间可调,抗压缩强度达到4.5MPa~120MPa,空心玻璃微珠表面改性剂的加入,明显提高了复合材料的机械性能,在600~9000MHz频率条件下,其介电性能基本不随频率而变化,介电常数为2.01~2.05,介电损耗角正切为2.57×10-3-2.80×10-3,空心玻璃微珠/环氧树脂复合材料具有较高的使用温度,扫描电镜表明表面改性剂改善玻璃微珠的浸润性,并且验证了空心玻璃微珠级配理论.
