Deformation-Driven Processing of CNTs/PEEK Composites towards Wear and Tribology Applications

Despite wide applications in mechanical transmission components, sparked with extraordinary wear resistance, polymeric composites face the challenges of reinforcement agglomeration. In this work, deformation-driven processing was proposed to prepare carbon nanotube (CNTs)-reinforced poly-ether-ether-ketone (PEEK) matrix enhancement resistance. Severe plastic deformation contributed homogeneous dispersion reinforcements without undesirable Low frictional heat input ensured structural integrity CNTs. The coefficient friction and rate 3.0 wt.% CNTs/PEEK were, respectively, 7.32% 6.71% lower than those pure PEEK. This strategy provides a high-efficiency approach preparing high wear-resistance composites, attributed its self-heating, low-cost, high-performance characteristics.
