Wear Behaviour of PLA, ABS and Alumina Filled PLA Composite: A Comparative Study

Wear behaviour of 3D printed Poly Lactic Acid and fusion deposited alumina filled Poly Lactic Acid was investigated and compared to 3D printed Acrylonitrile Butadiene Styrene (ABS) with objectives for replacing petroleum-based polymers and their into automobiles. Since, petroleum-based polymer and their composites damage land, water and air causing natural resource depletion. This experiment was carried on the DUCOM TR-20LE (pin-on-disc) apparatus according to ASTM G99 standard under dry sliding condition that were carried out at room temperature. The load was varied 4.905 (N) to 34.335 (N) at speed of 500 RPM for the run time of 5 minutes. The results shown that applied load significantly affect explicit rate of wear, friction force, volume loss as well as frictional coefficient of specimens. According to the results of the experiment, alumina filled PLA specimens performed similarly to ABS specimens. This research will help to develop or replace petroleum-based polymers in a variety of applications.
