以超细水晶粉为填料,用不同的组成和工艺制备水晶粉/环氧树脂复合材料。对水晶粉/环氧树脂复合材料的抗剪切强度、热膨胀系数进行较系统的研究,并用扫描电镜(SEM)对水晶粉/环氧树脂复合材料断面显微结构进行了观察。结果表明随填料含量增加可以适当提高复合材料的抗剪切强度,而降低其热膨胀系数。
To the superfine crystal powder as filler, with different composition and process of crystal powder / epoxy composite material. The shear strength and thermal expansion coefficient of crystal powder / epoxy composites were studied systematically. The microstructure of crystal powder / epoxy composites was observed by scanning electron microscopy (SEM). The results show that with the increase of the filler content, the shear strength of the composites can be properly increased and the thermal expansion coefficient can be reduced.
