Direct roving is a type of reinforcement material used in composite manufacturing, particularly in the production of fiberglass-reinforced composite products. It consists of continuous strands of glass fibers that are gathered and assembled into a single bundle without any twist. The defining characteristic of direct roving is that the glass fibers are collected together into a single bundle without any twisting or crimping. This arrangement allows for excellent tensile strength and efficient resin impregnation. Direct roving can be used with various resin systems, including polyester, epoxy, vinylester, and thermoplastic resins. This versatility makes it suitable for a wide range of applications.
