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,并用扫描电镜对水晶粉/环氧树脂复合材料断面显微结构进行了观察.实验结果表明随水晶粉填料含量增加可以适当提高复合材料的抗剪切强度、降低热膨胀系数,并得到最佳的三维混合均匀组织结构.水晶粉含量增加与抗剪切强度提高不呈线性关系,超细水晶粉添加量有最佳点;随之的热膨胀系数降低,三维结构均匀优化也有类似的拐点现象.

Crystal power/epoxy resin composite was made with refined crystal power as filling material in different composition. The shearing strength and coefficient of thermal expansion of the crystal powder/epoxy resin composite was studied. The sectional morphology was observed under a scanning electron microscope. The results of the study indicate that the shearing strength of crystal powder/epoxy resin composite is improved while the coefficient of thermal expansion decreases with increase of the amount of crystal powder, and a well-proportioned three-dimensional structure is obtained. The augmentation of shearing strength exhibits no linear relationship to the amount of crystal powder, and there is an optimal amount for crystal powder filling. The coefficient of thermal expansion is decreased with increase of crystal powder filling, and three-dimensional structure optimization exhibits the' similar inflexion.
