Abstract : The friction and wear properties of copolymers of dimenthyl (DM) and methyl trifluoropropyl (TFP) siloxane and of ATBN and CTBN rubber modified epoxies were previously reported. In the continuation of this work the friction and wear of the copolymers of dimethyl and diphenyl (DP) siloxane modified epoxies were measured. In addition, an abrasive wear experiment was performed to determine if the wear rates varied as the inverse of the energy to rupture of the materials. Another experiment was performed in which the wear debris produced was blown out of the wear track to test the hypothesis that the wear debris changed the predominant wear mechanism from fatigue to abrasive and thus caused a higher wear rate. The experiments and the results are described in this report.
