Research and Development of Prefabricated Airfield and Road Surfacing Membrane.
Abstract
For the production of the fabrics, fiber performance, yarn construction, weave construction for grab and tear strength, flexibility, winding equipment, dressing equipment, loom requirements, and salvage requirements were considered. The final fabric product is clearly superior to any fabric heretofore available and is substantially different from any fabric available at the beginning of this work. For the designation of the rubber compound, the commercially available polymers were screened and all promising materials were investigated in their available forms. The optimum material, a neoprene latex, was chosen. To properly optimize the performance of the membrane, the rubber must be prepared with additives. Some of the rubber considerations were: toughness, abrasion resistance, self-extinguishability, fiber wettability, penetration of the fabric, bonding to the base fabric, high strength adhesive joins, flexibility, U.V. resistance, jet-fuel resistance, and temperature resistance. The final membrane sample used one basic rubber with three different levels of binding additive. The final rubber combination is satisfactory in all respects. It was found that priming of the fabric to promote rubber bonding is mandatory for a suitable material to be developed. For the combination of fabric, primer, and rubber to yield a satisfactory membrane material, many manufacturing variables were considered. Techniques were developed for this purpose.
