A process of forming the fiber preform includes providing a substrate, applying a first layer of a fiber bundle to the substrate in a predetermined pattern having a principal orientation, stitching the first layer of the fiber bundle to the substrate using a thread, building up subsequent layers of the fiber bundle from the first layer, and stitching each of the subsequent layers to a preceding layer using the thread. A process of forming a unitary reinforced composite material includes the fiber preform. The process of forming a unitary reinforced composite component includes placing the fiber preform a mold platen, heating the perform to promote fusion of the thermoplastic fibers therein, cooling the perform until solidified with contours of the component, and removing the vehicle component from the mold platen.
