Abstract: Systems and methods for arresting aircraft. In specific embodiments, the systems and methods can be useful in arresting light aircraft because they typically do not have the weight to penetrate available EMAS systems. The system is generally provided as a structure having a suspended layer of energy absorbing material. A lower portion of the system can have a lower strength, used as a method to suspend an upper, stronger/more highly energy absorbent portion of the system.

Abstract: Embodiments of the present invention relate to composite materials for use as a vehicle arresting system (also referred to as an Engineered Material Arresting System (EMAS). Specific embodiments may use modified polymeric foams composites. The polymeric foams may include additives, coatings, combinations of both, or other features than render them useful for an EMAS. The polymeric foams may also have one or more modified surfaces that provide a protective crust. For example, the one or more surface may be modified by application of heat in order to help close the polymeric foam cells and/or to create an encapsulative surface. These features can provide enhanced weather resistance, fire resistance, moisture absorption, jet blast resistance, improve their energy absorbing properties, or other desired features.

Abstract: Embodiments of the present invention provide a core of individual components having properties such that a system assembled from the components absorbs the kinetic energy of a moving vehicle. The components may be interlocking components. The components may be manufactured of ceramic or polymeric composite or other materials that are strong enough to absorb the vehicle's energy and help stop the vehicle safely by the system's ability to crush or deform upon impact, and not so strong that it causes the vehicle to crumple against the barrier. In one particular embodiment, the components may be modified packing elements that are traditionally used in gas to liquid columns.
