Abstract

A high performance cyanate ester system suitable for RTM process was developed, which is made of low viscosity bisphenol E cyanate ester. The viscosity of the resin system is 200mPa∙s at ambient temperature with suitable pot life (>10h) and thus meet the needs of RTM techniques at ambient injection temperature.

Quartz/cyanate ester composites were fabricated by RTM technique. The processing characteristics, mechanical, thermal and dielectric properties were studied. The glass transition temperature is 230oC. The dielectric constant is 3.4 and dielectric loss factor is 0.006, suggesting that this quartz/cyanate ester system fabricated by RTM process has great potential to be used for advanced structural/functional composites.

Keywords: Cyanate ester, RTM, High performance
