Abstract: Forming process, dielectric properties and mechanical properties of quartz fiber and alumina fiber reinforced phosphate matrix composites were studied in the paper, and the major reason was analyzed which affected the stability of the mechanical properties at the high temperature. Quartz fiber and alumina fiber reinforced phosphate matrix wave-transmitting composites were prepared, which could be applied stably at the temperatures of 300 ℃ and 700 ℃ separately, whose dielectric loss were less than 0.015 ranging from 8 GHz to 18 GHz. They are a sort of wave-transmitting and high temperature resistance composites, with low dielectric loss in the broadband frequency.

Key words: phosphate matrix, composites, wave-transmitting
