Coupling agents are used to improve adherence of resin to filler surfaces. fPhysical Characteristics. Fiber-reinforced composites (FRCs) are a group of nonmetallic biomaterials that are growing in popularity in several dental applications. FRCs are structural materials with two distinct constituents. The reinforcing component provides stiffness and strength while the surrounding matrix supports the reinforcement and provides workability. The fibers most commonly employed in dental applications for reinforcement are polyethylene, glass, polypropylene, carbon or aramid. Today, epoxy adhesives are sold in local hardware stores, and epoxy resin is used as the binder in countertops or coatings for floors.
