Abstract
Disclosed are profiles of fiber-reinforced polymeric plastic and a pultrusion apparatus and method for the manufacture thereof. The apparatus is preferably vertically disposed. As one or more fibers is fed into the apparatus, each fiber is spread and wetted with monomer resin in a bundle spreader, formed in a die, and then subjected in a curing chamber to a source of radiation which initiates polymerization of the monomer, resulting in a fiber-reinforced polymeric plastic exiting from the pultrusion apparatus. Suitably, the radiation is ultraviolet, the monomer resin is methacrylate resin, and the fiber is quartz. The resultant profile is long and thin like a structural steel wire, but typically will have only 1/4 the weight thereof while having a strength comparable thereto. Thus, the profile is useful as an orthodontic wire as a replacement instead of structural steel wires used as orthodontic wires. Several profiles can also be aggregated and the aggregate used to make, for instance, artificial limbs or other structural products.
