Title:
METHOD FOR PRODUCING FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/032569
Kind Code:
A1
Abstract:
This method for producing a fiber-reinforced composite material comprises: a fiber dispersion step for providing a fiber-dispersed resin by kneading a resin 10a with a fiber 10b to disperse the fiber 10b in the resin 10a; and a molecular weight reduction step in which, while transporting the fiber-dispersed resin along an outer peripheral surface of a screw body 37 provided with a passage 88 in the interior, the fiber-dispersed resin is passed from an entrance 91 to the passage 88 to an outlet 92 of the passage 88 and in combination therewith a shear force is applied to the fiber-dispersed resin by restricting the transport of the fiber-dispersed resin with a barrier element 82 disposed between the inlet 91 of the passage 88 at the outer peripheral surface and the outlet 92.
