Thermal effects introduced by friction on contact behaviors and relative fatigue lives of composites

Key Points

• Fatigue lives in composites decreased significantly when subjected to high thermal effects from friction, indicating a critical relationship.
• Experiments revealed an average reduction in fatigue life by 25% with increased frictional heating in composite materials under stress.
• Analytical approach employed to assess thermal effects induced by friction on contact behaviors in various composite samples.
• Implications stress the need for improved composite designs to mitigate fatigue and enhance performance under friction.
