Study on Properties of 5528 Cyanate Resin Matrix GFRP

Heat resistance, mechanical, hydrothermal and dielectric properties of novel modified 5528 cyanate ester resin matrix glass fiber reinforced composites is investigated in this article. The results show that 5528 cyanate resin GFRP has good mechanical and dielectric performance. The dielectric constant and loss of quiz/5528 composites is 3.40 and 0. 00393 respectively and shows the excellent stability for microwave frequency. The dielectric constant of high - strength GFRP is 0. 00925, which has advantages over epoxy and bismaleimide resin matrix composites. 5528 cyanate resin matrix composites can be used for the high- performance microwave- transparence materials and high frequency PCB.
