The Effect of Fillers on Chrome-Based Wave-Transparent Material Matrix

Abstract:

Phosphate of chrome-alumina (PCA) matrix composites were successfully prepared via thermoforming by using chrome-aluminum phosphate as adhesive, ZnO as curing agent and single component or combination of Al₂O₃, SiO₂, SiC and Si₃N₄ as fillers. We have studied the effect of different fillers on the mechanical properties, dielectric properties and moisture absorption rate of composite materials. Results show that, for the PCA-III system, when curing temperature is 180°C, the dielectric properties of materials are the best and the moisture absorption rate is the minimum; When the amount of filler is 35%, the mechanical properties of PCA-III system are the best (i.e. the tensile strength is 94.4MPa and the flexural strength is 134.7MPa).
