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.
