ABSTRACT
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.
