Abstract
Apparatus and method for the pultrusion of polymeric resins reinforced with continuous lengths of multifilaments and/or fibers comprises wetting the lengths of multifilaments and/or fibers with a polymerization initiator, passing the wet length through an impregnating bath of a resin prepolymer and activating the polymerization in-situ.
Claims3
Pultrusion assembly for impregnating a continuous length of multifilaments or multifibers, which comprises;
- (a) a polymerization initiator bath vessel;
- (b) a molten thermoplastic prepolymer resin container;
- (c) a heat zone for polymerizing molten thermoplastic prepolymer resin;
- and
- (d) means for tracting the continuous length of multifilaments or multifibers sequentially through the bath vessel, the resin container and the heat zone.
