Abstract: A prepreg preparation device and a prepreg preparation method using the same are disclosed. According to an embodiment of the present invention, the prepreg preparation device comprises: a flow path-type impregnation part for impregnating, with a resin, a reinforced fiber transferred along a flow path; and a box-type impregnation part for impregnating, with the resin, the reinforced fiber transferred through a box-type space by passing through the flow path-type impregnation part.

Abstract: Disclosed are a prepreg manufacturing device and a prepreg manufacturing method using the same. A prepreg manufacturing device according to an embodiment of the present invention comprises: a first resin inflow part which is formed inside an upper mold, receives a resin supplied from an extruder, and discharges the resin to a reinforced fiber flowing to a lower part in the upper mold; and a second resin inflow part which is formed inside a lower mold, receives the resin supplied from the extruder, and discharges the resin to the reinforced fiber flowing to an upper part of the lower mold.

Abstract: The present invention provides buckling inducing-type vehicle crash boxes. The buckling inducing-type vehicle crash boxes are arranged at both ends of a back beam and comprise: a box body part; and a reinforcing part, which is formed in a lattice shape, is formed to integrally protrude from the outer surface of the box body part, induce buckling along the longitudinal direction of the box body part by an external impact, and absorb energy generated by to the impact.

Abstract: Provided is a continuous fiber reinforced composite including a thermoplastic resin, fibers, and metal wires. Also provided is a method of preparing a continuous fiber reinforced composite, and the method includes impregnating fibers provided from at least one fiber creel or metal wires provided from at least one metal wire creel in a thermoplastic resin to form a melt; molding a shape of the melt by using a mold and curing the resultant by heating in a heating tube to form a primary cured product, as a primary molding process; re-molding the primary cured product by using the mold again and curing the resultant by heating in the heating tube to form a secondary cured product, as a secondary molding process; and cooling, pultruding, and cutting the secondary cured product to perform finishing of the product.
