The present disclosure relates to a multilayer composite that may include a first porous layer, and a first barrier layer overlying the first porous layer. The first barrier layer may include a polyaramid material, a polyimide material, or any combination thereof. The multilayer composite may have a flame resistance rating of at least about 180° C. and a 50% strain compression rating of not greater than about 600 kPa.

A lightweight battery housing for an automobile and method of assembling same. The lightweight battery housing comprises an upper cover, a tub, and a protection frame whereon the upper cover and lower tub sit. The upper cover and tub may comprise at least one of a steel material, an aluminum material, and/or a fiber-reinforced composite. The protection frame comprises at least one of steel material and aluminum material. The tub includes pockets for holding battery modules and seals against the cover to provide a leak-resistant battery holder. Fasteners connect the tub, cover, and protection frame and a seal is placed between the tub and the cover. The cover and other components of the battery housing may be integrated directly into a body-in-white of the vehicle.
