Direct Roving for Thermoset Composites
Direct roving – also called single-end roving – for thermoset composites is used in pultrusion processes and to produce woven fiberglass fabrics. During the fiberglass production the direct roving is treated with a silane-based sizing to ensure compatibility with thermosets such as UP, VE, and epoxy resins. The products made of this direct roving find their way into infrastructure, construction materials, transportation equipment, open mesh for abrasive materials / grinding wheels, building facades, road reinforcements and much more.
What is a single-end roving (direct roving)?
A direct roving or single-end roving is manufactured by winding fiberglass directly into a clearly defined tex or yield. It is designed to be used mainly as an input for weaving processes, providing easy unwinding due to even tension, low fuzz generation and excellent wettability. It can be utilized in different process technologies, such as pultrusion or filament winding. The end-use composites applications can be found in infrastructure, building, marine, sport & leisure, and water transportation.
