Abstract
- This article addresses the question what the influence is of size and shape of glass both particles and fibers, as well as carbon fibers on the abrasiveness of polytetrafluoroethylene (PTFE)/epoxy composites sliding against steel balls. A size-dependence appears, i.e. large size glass particles (approximate to 80 mu m, L) are more abrasive than medium-size (approximate to 50 mu m, M) and small-size (approximate to 27 mu m, S) glass particles. Longer glass fibers (submilimeter) are more abrasive. Nevertheless, longer glass fibers still enhance the intrinsic mechanical properties of the composites. Also, carbon fibers reinforced composites yield much better mechanical properties than the glass fibers reinforced composites, but much more abrasive wear on the steel ball due to less surface-adhered polymer layers on fibers. Mechanical properties are enhanced by an increasing amount of glass fillers and by adding a small concentration of nanofillers. POLYM. COMPOS., 39:698-707, 2018.
