Basalt fibre is a promising mineral fibre that has high potential to replace synthetic based glass fibre in today’s stringent environmental concern. In this study, friction and wear characteristics of glass and basalt fibres reinforced epoxy composites were studied and comparatively evaluated at two test stages. The first stage was conducted at fixed load, speed and distance under three different conditions; adhesive, abrasive and erosive wear, wherein each composite specimens slide against steel, silicon carbide, and sand mixtures, respectively. The second stage was conducted involving different types of adhesive sliding motions against steel counterpart; unidirectional and reciprocating motion, with the former varied at pressure—velocity (PV) factor; 0.23 MPa·m/s and 0.93 MPa·m/s, while the latter varied at counterpart’s configuration; ball-on-flat (B-O-F) and cylinder-on-flat (C-O-F). It was found that friction and wear properties of composites are highly dependent on test conditions. Under 10 km test run, Basalt fibre reinforced polymer (BFRP) composite has better wear resistance against erosive sand compared to Glass fibre reinforced polymer (GFRP) composite. In second stage, BFRP composite showed better wear performance than GFRP composite under high PV of unidirectional sliding test and under B-O-F configuration of reciprocating sliding test. BFRP composite also exhibited better friction properties than GFRP composite under C-O-F configuration, although its specific wear rate was lower. In scanning electron microscopy examination, different types of wear mechanisms were revealed in each of the test conducted.

This paper reports the effect of 1.0 wt%, 3.0 wt% and 5.0 wt% nanoclay loadings on specific wear rate properties of basalt fibre reinforced polymer (BFRP) composites. The specific wear rate properties of the BFRP composites were analysed at three different wear conditions, i.e. dry adhesive sliding, two-body abrasion and slurry pot erosion in which the composites slide against smooth steel, rough silicon carbide and medium coarse sand mixture, respectively. The operating parameters for the wear tests were set at 30 N load, 300 rpm speed and 10 km distance. The results demonstrated that nanoclay incorporation enhanced the adhesive and erosive wear properties of BFRP composites up to 32% and 51%, respectively. In contrast, nanoclay incorporation deteriorated the abrasive wear properties of BFRP with increasing in nanoclay loading. The morphology of worn surfaces was evaluated using scanning electron microscopy (SEM) to study the wear behavior of the nanoclay modified BFRP composites. It concluded that nanoclay incorporation exhibited significant influence on wear properties of the polymer composites depending on the wear environment condition.
