Abstract: Various embodiments of the present invention provide a blast-resistant reinforcement assembly and/or system for engaging a surface of an existing structure to protect the structure from an applied force, such as an explosive detonation. The assembly includes one or more energy absorbing panels that may be attached to the structure. The energy absorbing panels include a core material configured to absorb some portion of the applied force by pulverizing in response to the applied force. In some embodiments, the energy absorbing panels also include one or more ballistic-resistant composite panels configured to protect the core material and the underlying existing structure from debris. Some embodiments further provide one or more energy deflecting panels engaged with the plurality of energy absorbing panels so as to be disposed between the energy absorbing panels and the location of the applied force for at least partially deflecting the applied force.

Abstract: A ground cargo vehicle has a chassis, multiple wheels mounted on the chassis such that the chassis is mobile upon the wheels, and a cargo compartment mounted on the chassis. The cargo compartment includes at least one panel constructed of a reinforced polymer composite material, and a lowered floor disposed lower than the top of at least one of the wheels. The vehicle may be powered by a hybrid drive system mounted on the chassis, the hybrid drive system including an internal combustion drive component and an electrical drive component. The floor may have a roadway height of less than 14 inches. The cargo compartment, cab compartment, chassis, and floor of the vehicle may be constructed entirely of lightweight reinforced polymer composite material.
