Thermoplastic composite bearings: tribological properties as a function of the material structure

摘要

In the study presented here; thermoplastic filament winding of uournal bearings with functional properties over their cross sections was performed by the use of journal bearings with functional properties over their cross sections was performed by the use of different commingled yarns. The raw material of the sliding surface consisted of PTFE-, aramid-, and polyamide fibers, of which the latter were molten and then transferred into the final matrix of the composite tube element. For this special filament winding process, the processing parameters were optimized, in order to realize a bulk composite structure. The composition of the raw materials and the winding geometry were varied. Thus, the influence of these parameters on the tribological behaviour of the bearing could be determined.
