Underbody shield materials that can provide an underbody shield with high impact resistance are described. In some configurations, an underbody shield composition comprises a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material. In some instances, the underbody shield composition may also comprise a film such that an underbody shield produced from the composition can withstand at least 50 individual impacts as tested using a SAE J400 protocol.
