A continuous composite fabrication technique
A molding process applying resin-impregnated roving and mats in the manufacture of rods, tubes and structural shapes of a uniform cross-section. The rovings, after passing through the resin dip tank, is drawn through a die to form the desired cross-section.
An automated, continuous process for manufacturing composite rods, tubes and structural shapes having a constant cross section. Roving and other reinforcements are saturated with resin and continuously pulled through a heated die, where the part is formed and cured. The cured part is then cut to length.
A continuous moulding process that mechanically aligns long strands of reinforcements for a composite material then passes them through a bath of thermosetting resin. The coated strands are then assembled by a mechanical guide before the curing process. More information can be found at The pultrusion process (About Composite Materials, USA).
A continuous process for manufacturing composites in rods, tubes, and structural shapes having a constant cross-section. After the reinforcement is passed through the resin-impregnation bath, it is drawn through a shaping die to form the desired cross-section; curing takes place before the laminate can depart from that cross-section.
Lineal profiles of constant cross section manufactured by combining plastic resin and continuous glass fiber reinforcement. These thermally insulating and structural components are ideally suited for applications where strength, thermal stability and weather resistance are required, such as in patio door frames and commercial windows.
The method used to join glass fibers and resins through lineal-forming machines with the end result begin a formed profile that when joined to other profiles, form a window, door or sash frame.
The process used to produce fiberglass composite profile or component used for the production of windows and doors. Term is also used generally to refer to the composite profiles or lineals cut and processed to make window and door components.
The shaping of an object, such as those made of fiberglass, by pulling it through a die.
Pultrusion is a continuous process of manufacturing of composite materials with constant cross-section whereby reinforcing fibers are pulled through a resin, possibly followed by a separate preforming system, and into a heated die, where the resin undergoes polymerization. Many resin types may be used in pultrusion including polyester, polyurethane, vinylester and epoxy.
