Abstract: The present disclosure provides a composite material housing for a battery pack for reducing or minimizing thermal runaway propagation. The composite material housing includes a polymeric structure defining an interior-facing surface and an exterior-facing surface. The polymeric structure includes a fire resistant material layer and a reinforcing material layer, where the fire resistant material layer defines an interior-facing surface, and the reinforcing material layer defines the exterior-facing surface. The composite material further includes a metallic layer disposed along the exterior-facing surface, where in a first operational mode the metallic layer contacts the exterior-facing surface and in a second operational mode, after exposure to a thermal load of greater than or equal to about 500° C., the metallic layer at least partially delaminates from the exterior-facing surface and forms one or more insulating air gaps that define a thermal barrier.
