Evaluation of Goodyear Medium-Duty Aluminum Honeycomb Landing Mat
Abstract
The report describes an investigation to evaluate a medium-duty aluminum honeycomb-core landing mat designed and fabricated by Goodyear Aerospace Corporation, Akron, Ohio, as a result of the Government request for proposal dated 6 May 1968. The medium-duty mat was a sandwich-type structure with a honeycomb core bonded by an epoxy film adhesive to aluminum top and bottom skins. Extruded aluminum edge connectors were also bonded with a similar adhesive to the top and bottom skins and to the core. Individual panels were joined along two edges with a hinge-type connection and along the adjacent two edges by overlap-/underlap-type connections that were locked together by insertion of a connector bar. The panel dimensions, weight, and placing rate were 4 ft by 4 ft by 1.5 in., 67.5 lb, and 478 square feet per man-hour, respectively. The weight per square foot of placing area was 4.1 lb. Traffic and skid tests were conducted to obtain information for evaluating the service life and performance of the medium-duty mat as specified by project requirements. Laboratory tests were performed to determine the mechanical properties of the mat panels and their component parts, and results indicated that the materials in the mat met the specified requirements. The traffic tests were conducted with a rolling wheel load, simulating aircraft operations on mat placed on a prepared subgrade.
