WebbThermoset composite matrices include polyesters, vinyl esters, epoxies, bismaleimides, cyanate esters, polyimides and phenolics. Epoxies currently are the dominant resins … WebbThese agents reacts with the hydroxyl group of the fibers and the matrix's functional component, provides an interphase with improved adhesion properties at the fiber …
WebbThe thermoset matrix is only partially cured to allow easy handling; this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Hence, composite structures built of pre-pregs will mostly require an oven or autoclave to cure. WebbThermoset polymer such as epoxy, polyester, polyurethane, and vinyl ester resins are typically utilized as a coating or as a matrix material for reinforcement materials/fillers, forming a reinforced polymer composite ( Amaechi et al., 2024; Psomopoulos et al., 2024 ).
WebbThe thermoset (non-reinforced) and composites (phenolic matrices reinforced with randomly dispersed fibers) were characterized using TG, DSC, SEM, DMTA, the Izod impact strength test, and water absorption capacity analysis.
