WebThe potential hazards involve skin, eye, and respiratory contact with the ingredients or final formulation. Prepregging is the process where the resin and curing agent mixture are impregnated into the reinforcing fiber. These impregnated reinforcements (also known as prepregs) take three main forms: woven fabrics, roving, and unidirectional tape. WebPhenolic resins tend to be relatively cheap (certainly less than epoxies and polyimides), have high temperature resistance, and low flammability. Their main drawback is very low toughness, which tends to limit their applications to those where heat and combustion resistance is important. Sign in to download full-size image Figure 9.
