Fiberglass Direct Roving is a constant bundle of glass fibers that are impregnated with a sizing agent and thereafter wound onto a spool. This roving is utilized as a reinforcement material in manufacturing of composite materials. It has outstanding mechanical properties, such as high stiffness, and tensile strength, making it suitable for applications where structural integrity is essential like in wind energy and aerospace industries. The sizing agent utilized on the fibers can be custom-made for enhancing bonding with the matrix material like epoxy resin or polyester. Fiberglass Direct Roving is normally utilized in filament winding, weaving, and pultrusion processes.
