Preparation of boz/glass fibers/cyanate ester resins laminated composites

A novel kind of high performance laminated composites of Bis allyl benzoxazine/Quartz fibers/Cyanate ester (Bz‐ally/QFs/CE) have been developed. The effects of Bz‐ally on the moisture resistance, mechanical, dielectric, and thermal properties of Bz‐ally/QFs/CE laminated composites were investigated systematically. Compared with QFs/CE laminated composites, the flexural strength and the interlaminar shear strength value of the Bz‐ally/QFs/CE laminated composites were improved markedly with up to 25.2% and 22.3% increasing magnitude, respectively. Meanwhile, the Bz‐ally/QFs/CE laminated composites exhibit lower dielectric constant and loss than QFs/CE laminated composites over the testing frequency from 10 to 60 MHz. In addition, the thermal stability and moisture resistance of Bz‐ally/QFs/CE laminated composites were also superior to that of Boz/QFs/CE laminated composites. POLYM.
