A pultrusion machine for forming a laminated composite with a predetermined profile and the product obtained. The apparatus comprises at least two spools for supplying elongated reinforcements. A collator receives the elongated reinforcements and arranges the reinforcements in layered relationship to form a layered elongated bundle. A supply member wets the layered elongated bundle with plastisol to form a wetted elongated bundle. The wetted elongated bundle is transported through a pultrusion die wherein the wetted layered bundle is molded into the predetermined profile. A converting apparatus cures, or converts, the wetted layered bundle into the layered composite. A particularly preferred embodiment is an extrusion comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol.
A pultruded structural element prepared by the method of
A pultrusion apparatus for forming a structural laminated composite with a predetermined profile, said apparatus comprising:
The pultrusion apparatus of claim 4 wherein said supply member is an injector and said plastisol is added to said elongated bundle by said injector.
An extruded element comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol wherein said reinforced plastisol comprises a continuous fiber.
A method for forming a reinforced extrusion comprising:
A reinforced extrusion comprising:
