Dry Sliding Wear Performance of Thermoplastic Copolyester Elastomer Composites

Abstract:

This research work uncovers the wear performance of short glass fiber (SGF) fortified thermoplastic copolyester elastomer (TCE) hybrid composites loaded up with both micro (short carbon fibers, PTFE, SiC, Al₂O₃ and MoS₂) and nano(Al₂O₃ and PFPE) sized particulate fillers. The readied hybrid composites are tested for tribological performance using pin-on-disc test rig. Test outcomes uncovered that TCE hybrid composite strengthened with SGF and loaded up with PTFE, SiC, Al₂O₃ and MoS₂ displayed better wear resistance, however TCE hybrid composite loaded up with nanolubricating filler i.e. PFPE displayed slightest friction coefficient (μ) in the investigation. This study additionally archives the impact of tribological control factors such as sliding distance, sliding speed and filler content on tribological conduct of TCE composites in terms of specific wear rate (K_s) and μ.
