What type of resin dissolved in styrene is typically used when laminating fiberglass reinforced plastics?

When laminating fiberglass reinforced plastics, the typical resin is unsaturated polyester resin, which is a polyester resin dissolved in styrene. Styrene acts as a reactive diluent and monomer, lowering the resin’s viscosity so it can wet out and infiltrate the glass fibers evenly, while also becoming part of the polymer network during curing with a peroxide initiator. This combination is inexpensive, repairs well at room temperature, and is forgiving in lay-up processes, making it the standard choice for FRP laminates. Other resins exist for specialized needs—epoxy resins are costlier and use different curing systems, vinyl ester resins offer superior chemical resistance, and urea-formaldehyde resins aren’t suitable for FRP due to brittleness and moisture issues.
