Analysis of Lightweight Materials for the AM2 System

Abstract

An analysis was performed on potential materials that could replace the 6061-T6 aluminum alloy currently used in the AM2 airfield matting for the purpose of light-weighting the design. An in-depth analysis was performed on metal and polymer matrix composites. However, neither groups of materials produced a suitable material based on operating conditions of the AM2. Newly developed extruded magnesium alloys were identified that could potentially provide weight savings of 30 to 40% while maintaining the current performance of the AM2. In addition, traditional high-strength aluminum alloys were identified that could provide substantial weight savings. However, manufacturing issues existed due to the high strength of these aluminum alloys. Finally, analysis was performed to determine the cost of manufacturing the AM2 using these alternate materials.

Effect of Geometry and Infill on Strength of 3D Printed Planar Matrices for Matting Applications

“…AM-2 is a versatile system that can handle multiple kinds of aircraft (6)(7)(8)(9), but poses logistical constraints arising from size and weight, and cannot be manufactured in theater or on demand. Alternative matting solutions have been developed and are constructed from lighter weight materials, such as fiberglass (10), composite materials (2,11), and polymers (12)(13)(14). While these mats have yet to replace AM-2, they demonstrate that polymer-based matting can serve as a viable and versatile alternative.…”
