Abstract: A bumper back beam for a vehicle may include side portions connected to a vehicle body and formed of general plastic on both sides and an intermediate portion connecting the side portions on both sides and formed of high-strength plastic and a predetermined section, both ends of which encroach into the side portions to form overlap sections.

Abstract: A CFRP plate having a steel plate wherein a weld nut is welded is integrally stacked, and a manufacturing method are provided. The CFRP plate is formed by interposing a steel plate having a weld nut welded to a lower surface between two adjacent CFRP layers. A foam is interposed between a layer when the steel plate is disposed and a layer below the layer when the steel plate is disposed. The guide pins are fitted into the steel plate, a second layer, and the foam, forming an aperture in a portion of a second layer where the weld nut is positioned. A grove is formed accommodating the weld nut in the foam positioned below the aperture. A resin is injected when a temporary bolt is fitted into the weld nut, and the temporary bolt is removed after the resin is injected.

Abstract: The present invention provides a continuous fiber-reinforced resin composite material which is a laminate in which a continuous fiber layer and a resin layer are alternately laminated, wherein the resin layer is a layer formed by including a thermoplastic resin or a thermosetting resin, and the continuous fiber layer includes a structural frame of continuous fibers formed by arranging continuous fibers side by side, wherein the thermoplastic resin or the thermosetting resin, originating from the resin layer, penetrates into the structural frame of continuous fibers to form a resin-impregnated continuous fiber, such that a part of the structural frame of continuous fibers is the resin-impregnated continuous fiber and the remainder of the structural frame of continuous fibers is a resin-non-impregnated continuous fiber into which the thermoplastic resin or the thermosetting resin is not penetrated.

Abstract: Disclosed is a battery pack case assembly for an electric or hybrid vehicle and a method for manufacturing the same. The battery pack case assembly includes a case body and a cover. The case body receives a battery pack, and the cover is coupled to the case body. The case body is formed of a plastic composite in which a long fiber or a blend of a long fiber and a continuous fiber is used as a reinforcing fiber in a plastic matrix. A separate reinforced member is bonded to both side bracket parts for coupling to a vehicle body, and is formed of a plastic composite in which a long fiber, a continuous, or a blend of a long fiber and a continuous fiber is used as the reinforcing fiber in the plastic matrix.

Abstract: The present disclosure relates to a bumper back beam to be disposed inside a bumper cover, for reducing impact from outside the bumper cover. The bumper back beam includes a body including a synthetic resin, and a fiber composite reinforcing material including a hollow section. The fiber composite reinforcing material is fastened inside the body. The bumper back beam has high reliability, by having excellent ability to absorb impact energy because cracks almost do not occur during collision since it not only provides satisfactory strength and stiffness but also has high elongation with synthetic resin and fiber composite reinforcing materials generating synergies, and especially by having excellent impact resistance since fiber composite reinforcing materials take the shape of a hollow section.
