1. A method of forming a shell of a crush countermeasure for a body-in-white (BIW) structural vehicle component, comprising:
forming a laminate by:
feeding a fiber structure and a resin to a heated belt laminator to form a layup, wherein the layup comprises alternating layers of the fiber structure and the resin, wherein fiber structure, for each one of the layers, is a unidirectional fibrous tape;
laying up the fiber structure such that, within the layup, fibers of the fiber structure within each one of the layers are oriented at a different angle than the fibers within at least an adjacent one of the layers; increasing a temperature and a pressure to flow the resin into the fiber structure to form the laminate; and
cooling the laminate to solidify the laminate; and
forming the laminate into a U-shape of the shell of the crush countermeasure such that the shell comprises two walls extending parallel to each other from a back and forming a shell channel, having a major axis extending between open ends of the shell channel, wherein the two walls extend continuously along the major axis, between the open ends of the shell channel; and
forming a ribbed or honeycomb shaped reinforcement along the shell channel with a chopped fiber reinforced polymer.
