Wet Clutch Lining-Lubricant Additive Interactions

Lubricant and lubricant additive interactions with clutch linings and lining materials were measured at elevated temperatures. Swelling, weight, and compressibility changes were related to material chemistry and endurance test results. Interactions of specific clutch lining ingredient-lubricant additive combinations were identified to help explain why different clutch linings perform better in some lubricants than in others.
