Abstract:
A pultrusion method for forming a laminated composite with a predetermined profile and the product obtained. An apparatus is used that comprises at least two spools (2) for supplying elongated reinforcements (1). A collator (3) receives the elongated reinforcements (1) and arranges the reinforcements in layered relationship to form a layered elongated bundle (4). A supply member wets the layered elongated bundle with plastisol to form a wetted elongated bundle (8). The wetted elongated bundle (8) is transported through a pultrusion die (9) wherein the wetted layered bundle is molded into the predetermined profile. A curing section (11) cures, or converts, the wetted layered bundle (8) into the layered composite. A particularly preferred embodiment is an extrusion comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol.
Abstract:
PURPOSE: A fiber reinforced composite is provided to have low thermal conductivity, excellent material property such as strength due to the superior interfacial adhesion by using lyocell carbon fiber. CONSTITUTION: The fiber reinforced composite comprises Lyocell carbon fiber and polymer resin. The Lyocell carbon fiber includes the carbonized Lyocell fiber, is surrounded by the polymer resin, and manufactures the Lyocell fiber by heat-treating in a temperature range of 100 to 2800°C. The Lyocell carbon fiber is a long fiber structure comprised of filament thread, and has a woven fabric form. The polymer resin is phenol resin.
