Vinylester Polyester Resin System, also known as Fiber-Reinforced Polymer (FRP), is a type of composite material that combines a resin matrix with fiber reinforcement. This type of system is commonly used to create corrosion-resistant and lightweight structures, including flooring systems. The vinylester or polyester resin is combined with fiber reinforcement, typically in the form of fibers or mats made of glass, carbon or aramid, to create a strong and durable material.
