Pultrusion roving is a specially engineered reinforcement material made from continuous strands of glass fibers bundled together without twist, optimized for use in pultrusion manufacturing. In this process, rovings are continuously drawn through a resin bath and then into a heated die to form rigid, lightweight, and high-strength composite profiles.
Pengenalan kinerja produk
This product plays a central role in determining the final composite’s mechanical performance, surface quality, dimensional accuracy, Dan resin compatibility. Compared to other roving types, pultrusion rovings exhibit excellent linear tension consistency, superior resin wet-out characteristics, and optimized sizing chemistry to match specific thermoset or thermoplastic matrices.
2. Overview of the Pultrusion Process
Pultrusion is a continuous manufacturing process for producing linear, constant cross-section composite profiles. The process is efficient, highly automated, and ideal for high-volume production of items such as beams, rods, ladders, window frames, gratings, and cable trays.
Pultrusion Workflow:
-
Fiber Delivery: Pultrusion rovings are unwound from creels and guided into a resin bath.
-
Resin Impregnation: Fibers are thoroughly wetted in a resin matrix (polyester, vinyl ester, epoxy).
-
Preforming: Wet fibers are guided into the shape of the final profile.
-
Heating & Curing: Material enters a heated steel die where the resin cures and the profile is shaped.
-
Pulling & Cutting: Hardened composite is continuously pulled from the die and cut to length.
