Rubber Pads for Tank Track

Abstract

Investigations of rubber compounding, service test evaluation, and rubber-to-metal bonding were made. The injection-molding of track pads was attempted. Numerous compounds were developed for optimum properties, and track pads prepared from these compounds were service tested to determine actual wear resistance. Long-term aging tests on millable polyester urethane track pads and rubber-to-metal bonded specimens were completed. Compounds based on Stereon 750, HYTRANS elastomers, SBR/polybutadiene blends, and EPDM provided pads with improved tread wear. Little correlation was found between volume wear ratings based on service tests for cut crack growth, heat buildup, tear resistance, and abrasion resistance. Track pads prepared by injection molding had physical properties comparable to those of compression-molded pads. The preparation of rubber track pads, having significantly improved wear resistance, from certain low- cost, general-purpose type elastomers appears feasible.
