AI Technical Summary
Technical Problem
Thrust members made of thermoplastic resin for torque fluctuation absorbers suffer from poor wear resistance and unstable coefficients of friction, necessitating surface treatments like plating or painting to improve performance.
Method used
A sliding member composed of a resin composition containing a polyamide resin, fibrous reinforcing material with a tensile modulus of 190-300 GPa, and a polyamide-based elastomer, which provides excellent wear resistance and stable friction without surface treatment.
Benefits of technology
The sliding member exhibits a coefficient of friction of 0.40 or more against carbon steel S45C, ensuring stable performance as a thrust member in torque fluctuation absorbers without the need for surface treatments.
