The tribological behavior of multi-component polymeric composites will be studied, with emphasis on developing optimal materials combinations for tribological performance. Particular emphasis will be placed on the possibility of developing beneficial tribological films from decomposing fillers and solid lubricants added to polymeric materials for use under sliding conditions. The study will include synthesis of materials with fillers selected on basis of bonding strength, electronegativity, and heat of formation; with PTFE lubricant additions; and with carbon fiber reinforcements. The nature of the transfer film and its rate of formation will be investigated and correlated with the tribological events during sliding and with tribological properties such as friction and wear.

将研究多组分聚合物复合材料的摩擦学行为，重点是开发符合摩擦学性能的最佳材料组合。将特别强调从分解的填料和添加到聚合物材料中的固体润滑剂开发有益的摩擦学薄膜的可能性，以便在滑动条件下使用。这项研究将包括根据粘合强度、电负性和形成热选择填料的材料合成、添加聚四氟乙烯润滑剂和碳纤维增强材料。将研究转移膜的性质及其形成速度，并将其与滑动过程中的摩擦学事件以及摩擦和磨损等摩擦学特性相关联。
