Tribological performance of the blend PBT and short aramid fibers
Journal Title: INCAS BULLETIN - Year 2015, Vol 7, Issue 1
Abstract
Polybutylene terephthalate (PBT) and its aramid fiber composite (10 wt.%) were investigated in order to measure their wear and frictional properties under variations of applied load (5 N, 10 N, 15N) and velocity (0.25 m/s, 0.5 m/s and 0.75 m/s), in dry regime. The tribological properties of the composite were evaluated using a block-on-ring tribotester. The worn surface was investigated with a scanning electronic microscope and the authors pointed out particular processes taking place into the superficial layers of the friction couple. During the tests, temperature was measured by an infrared camera near to the contact of bodies that are involved and the friction coefficient was monitored by the help of the tribometer UMT-2 (Brucker-CETR®).
