Composites Resins
Resins play a pivotal role as the matrix material in composite structures, bonding and encapsulating reinforcements like fibers within the composite. These materials, commonly in liquid form before curing, undergo a transformation into a solid, durable substance. Resins vary widely in type, such as epoxy, polyester, vinyl ester, and more, each offering distinct properties like adhesion, flexibility, and temperature resistance. The selection of resin significantly influences the composite's final characteristics, including strength, durability, and chemical resistance.
