144706 - Disc Golf Materials Strength and Composition 

Injection molding, a manufacturing technique, involves producing parts by injecting molten plastic into a mold where it cools and solidifies into the mold shape. One such application of this method is the production of disc golf discs, where varying material characteristics are achieved using different polymer and elastomer plastic mixtures. These varied mixtures result in plastics with diverse physical and mechanical properties. This study investigates these properties for several commercially available discs through tensile testing per the ASTM D638 standard. Tensile samples were prepared by both laser cutting and die cutting purchased discs. To better understand the influence of plastic composition on mechanical properties, samples from each disc were analyzed by FTIR, CHN, ICP-OES, and TGA to elucidate their chemical makeup. Tensile test results showed discs with those with lower carbon/nitrogen content are much more brittle than plastics made with higher carbon/nitrogen mixtures. The brittle plastic also had little to no oxygen content and had more filler polyurethane material. Physical testing of the discs was also simulated by creating a launching mechanism to track the flights of new discs. The discs are then launched into a wall to create deterioration and wear. The materials are compared by how the flight properties change from this test procedure. This comprehensive study illustrates that injection molding plastics can manufacture a broad spectrum of polymers, each exhibiting distinct material characteristics.
