Title:
METHOD AND APPARATUS FOR PREPARING UNIDIRECTIONAL FIBER-REINFORCED RESIN BODY HAVING REGULAR CROSS SECTION
Document Type and Number:
WIPO Patent Application WO/2022/007038
Kind Code:
A1
Abstract:
A method and apparatus for preparing a unidirectional fiber-reinforced resin body having a regular cross-section. A die head (3) extruding melt resin extrudes a thermoplastic resin, which forms a cascade-shaped film layer and is poured onto a hot melt resin applying guide roller (4). A continuous fiber (1) passes along the hot melt resin applying guide roller (4), combines with the uniform resin on the hot melt resin applying guide roller (4), passes through multiple stages of open-ended continuous fiber and hot melt resin rolling and impregnation apparatuses which are arranged in parallel and in serial connection, and then passes through a splitting mold cavity (84), a bundling mold cavity (86) and a cooling-shaping mold cavity (87) to form at least one bundle of fusion sub-unit of the continuous fiber and the hot melt resin.
