    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: Arresting material test apparatus, test probes and test methods enable testing of compressive gradient strength of cellular concrete, and materials having similar characteristics, on a continuous basis from the surface of a section to a typical internal penetration depth of at least 60 percent of thickness. Previous testing of cellular concrete typically focused on testing to confirm a minimum structural strength prior to structural failure or shattering of a test sample. For an aircraft arresting bed, for example, cellular concrete must exhibit a compressive gradient strength in a relatively narrow precalculated range continuously from the surface to penetration depth equal to 60 to 80 percent of sample thickness. Precalculated and controlled compressive gradient strength is critical to enabling an aircraft to be safely stopped within a set distance, without giving rise to drag forces exceeding main landing gear structural limits. New test apparatus, test probes with post-compression build-up relief and test methods are described to enable such testing and recordation of data showing the gradient of compressive strength as it increases from the surface of a test sample to a predetermined depth of penetration. Resulting compressive gradient strength data is representative of performance of cellular concrete sections in decelerating an aircraft.

    Abstract: Vehicle arresting beds, for installation at the ends of aircraft runways, are effective to safely decelerate aircraft entering the bed. The arresting bed is assembled of a large number of blocks of cellular concrete having predetermined compressive gradient strength, so that aircraft landing gear is subjected to drag forces effective to slow a variety of types of aircraft, while providing deceleration within a safe range of values. An arresting bed typically includes an entry region of a depth increasing from 9 to 24 inches formed of blocks having a first compressive gradient strength. A second region, which may be tapered into the first region and increase in depth to 30 inches, is formed of blocks having a greater compressive gradient strength. An aircraft thus experiences increasing drag forces while it travels through the bed, to provide an arresting capability suitable for a variety of aircraft. A protective hardcoat layer of cellular concrete of strength greater than the blocks overlays the blocks to enable service personnel to walk on the bed without damage. Arresting bed systems may be provided in alternative configurations, such as a bed formed of an aggregate including pieces of cellular concrete with or without interspersed pieces of other compressible material and covered by a hardcoat layer.
