Thermoset matrix systems dominate the composites industry because of their reactive nature and ease of impregnation. They begin in a monomeric or oligomeric state, characterized by very low viscosity.

The reinforcement phase of these materials may consist of glass, carbon or aramid fibers in a matrix of resins such as polyesters, vinyl esters, epoxies or phenolics. Prior to impregnation of the ...

Unsaturated polyester resins can be adapted for the development of transportation, structural and construction profiles, as shown here. Photo Credit: Exel Composites A composite material’s key ...
