Abstract: A modular composite structure containing multiple individual composite structures attached together. The individual composite structures form sections of a vehicle component. The composite structures are lightweight and made of materials that can function to absorb energy or attenuate vibration or noise. The composite structures contain a core material adhered to a fiber layer and a fiber reinforcement region for improving the strength and stiffness of the modular composite structure. The modular composite structure can include multiple floor pan segments that can be attached to a central composite structure that can be a utility tunnel or housing.

Abstract: A modular composite battery enclosure containing multiple individual composite structures attached together. The individual composite structures form covers that enclose an open area for housing a battery system of battery cells and cooling devices. The composite battery enclosures are lightweight and made of materials that can function to absorb energy and insulate the battery housing area. The composite structures contain a core material adhered and sandwiched between fiber layers.

Abstract: An airless tire has a wheel portion and a webbing extending from the wheel portion towards an axis of rotation of the airless tire. The stiffness of the webbing varies along an axial direction of the airless tire. The diameter of an annular outer surface of the wheel portion varies along an axial direction of the airless tire.
