Study on the durability and wear resistance of Al2O3-SiCcomposite gripping element in sport shoes

Abstract

This study investigates the durability and wear resistance of gripping element assemblies through mechanical loading and weartesting. The gripping element assembly underwent 5,000 cycles of loading and unloading, with each cycle applying a maximumload of 1800 N for 1 minute. Continuous monitoring of load, displacement, and time revealed excellent durability, with novisible signs of deformation or damage observed. Additionally, the assembly underwent wear testing, enduring 5,000 cyclesof repeated contact with an abrasive surface under a constant load of 200. Minimal mass loss was measured after every 1,000cycles, indicating outstanding resistance to abrasion and wear. The structural integrity and tread surface profile remainedintact throughout the testing process, demonstrating the assembly’s ability to withstand prolonged usage without significantwear or deterioration. Furthermore, the study examines the relationship between mass loss and immersion time, revealinginsights into composite material degradation in corrosive environments. The inclusion of SiC particles in the matrix results inreduced weight loss post-corrosion, highlighting the reinforcing effect of clumped SiC particles on the matrix-reinforcementbond. The observed complexities underscore the need for further investigation into particle-matrix interactions to optimizecomposite materials for enhanced performance and durability in corrosive conditions.
