Abstract Details

2012, Master of Science, Ohio State University, Mechanical Engineering.
In this study, a family of experimental evaluations is performed to rank order various combinations of plastic materials and greases for their suitability for automotive auxiliary drive applications in terms of their friction and wear performances. The tests included three common plastic materials (PA46 with 30% glass fiber filler, PA66 with 30% glass fiber filler, and PEEK with 30% carbon fiber filler) and four different proprietary greases. A twin-disk set-up is employed to test plastic disk specimens against a steel roller for their traction characteristics as a function of the slide-to-roll ratio and their wear performance as a function of loading cycles. Friction and wear test results from all twelve plastic-grease combinations are compared to determine particular combinations that provide the best combined wear and traction performance. Results indicate that grease type has a great influence on the friction of the contact, with two of the greases resulting in drastically lower friction coefficients. The PEEK material is found to be the best in terms of its wear resistance. PA46 and PA66 materials with proper grease selection exhibit friction values that are better than PEEK while their wear depths are two to three times that of PEEK.
