Abstract
ABSTRACT Cyanate Ester–Epoxy blends and their glass–fabric reinforced composites with improved thermal, mechanical, and dielectric characteristics were developed through cost-effective out-of-autoclave process, resin film infusion. They are thermally stable at least up to 320°C with glass transition temperature up to 195°C. They have excellent structural characteristics in comparison to their pristine counterparts, and their crosslinking was validated with Fourier transform infrared. Electromagnetic properties such as ε’ (2.8–3.0), ε” (0.02–0.14), tan δ (0.008–0.051), and transmission loss of <−1.5 dB makes them ideal materials for electromagnetic transparent composites and for encapsulating applications for wideband microwave frequencies.
