| Abstract |
Management of waste tires has become a leading environmental issue due to the global growth in the number of tires produced annually. This work is focused on exploring the use of Ground Tire Rubber (GTR) in a new class of cost-effective, recycled composite materials. A Fused Filament Fabrication (FFF) desktop 3D printer is used to produce GTR-based composite material with up to 50% wt. rubber filling. ABS is used as the host matrix. Both microscopic and macroscopic characterization of the 3D printed composites are performed in addition to a baseline printed composite. Increasing the rubber content from 0 % wt. to 50 % wt. in the 3D printed GTR-based composite results in approximately 260% improvement in the overall damping properties. Results also indicate the average diameter of the rubber particles in the 3D printed composites increased as the amount of rubber content increased. Presumably, specimens with larger rubber particles yielded longer contact lines with the host polymeric matrix. Consequently, energy dissipation is improved, resulting in enhanced overall damping properties of the 3D printed composites. The enhanced damping capabilities as well as the low-production cost and lightweight characteristics of the presented GTR-filled composite yield new opportunity for application of these GTR-reinforced composites in automotive or other industries for making a wide variety of parts where these characteristics are highly valuable. |
