Microstructural Dependency of Diffusion in Glass Flake-Reinforced Vinyl Ester Resins

Effect of Micro Glass Flake on Morphological and Rheological Behaviour of Epoxy Vinyl Ester Composite Coatings

In the present work, attempts were made to investigate the reinforcement and treatment effect of GF on morphological and rheological behaviour of GF/epoxy vinyl ester composites. GF was incorporated into epoxy vinyl ester resin by sonication, and mechanical agitation. Rheological and morphological properties were studied as a function of particle treatment and size distributions. The dispersion...

Heat Resistant Vinyl Ester Resins for Composite Applications

Unsaturated polyester and epoxy vinyl ester resins have broad utility in composite applications. Today’s commercially available premium thermal performance vinyl ester resins are derived from novolac epoxies and methacrylic acid. These products combine low viscosity with shelf stable, yet fast curing properties, and enable fabricators to manufacture composite parts with rapid throughput for dem...

Microwave and Conventional Mechanical & Thermal Analysis of the Reactions in Epoxy Vinyl Ester Resins

Over a billion microwave ovens are used every day thus witnessing the importance of microwave heating in the world today. Microwave processing of polymers is a comparatively recent and vastly expanding field in industry due to economical advantages through energy saving and accelerated manufacture. Factors that hinder the use of microwaves in materials processing are decreasing every day. Epoxy...

Effects of Ultraviolet Radiation Exposure on Vinyl Ester Matrix Resins: Chemical and Mechanical Characterization

The increased use of fiber-reinforced vinyl ester composites in outdoor applications has led to questions concerning the environmental durability of these materials, particularly as related to UV exposure. In this work, artificial ultra-violet (UV) degradation was carried out on neat vinyl ester matrix specimens using an integrating sphere-based UV exposure chamber. Significant changes were obs...
