Role of Thermosetting Polymer in Structural Composite

Thermosetting resins are network forming polymers with highly crosslinked structure. In this review article, thermoset of epoxy, unsaturated polyester resin, phenolic, melamine, and polyurethane resin have been conversed. Thermosets usually have outstanding tensile strength, impact strength, and glass transition temperature (Tg). Epoxy is the most widely explored class of thermosetting resins. Owing to high stiffness and strength, chemical resistance, good dielectric behavior, corrosion resistance, low shrinkage during curing, and good thermal features, epoxy form the most important class of thermosetting resins for several engineering applications. Here, essential features of imperative thermosetting resins have been discussed such as mechanical, thermal, and non-flammability. At the end, employment of thermosetting resins in technical applications like sporting goods, adhesives, printed circuit board, and aerospace have been included
