Abstract

Friction and dry wear behaviour of glass fibre reinforced epoxy (GFRE) and glass fibre reinforced polyester (GFRP) composites are studied in the current project. Three sliding orientations of fibre with respect to the sliding distance are considered in the investigation, i.e. parallel orientation (P-O), anti-parallel orientation (AP-O), and normal orientation (N-O). On the other hand, different sliding distances (0- 15)km are accounted. The adhesive wear experiments were carried out using block-onring(BOR) configuration at room temperature, applied load of (30N), and sliding velocity of (2.8 m/s). Interface temperature and frictional force were captured and recorded during the sliding. Worn surfaces were examined by using (SEM) to
classify the damage. The results revealed that the highest wear rate is taken place in (AP-O) of GFRE. (P-O) is the highest wear rate of GFRP. On the other hand, the lowest wear rate is exhibited for (N-O) at longer sliding distance. The maximum friction coefficient is observed when sliding take place in (N-O and P-O) at higher speed level. Although, (AP-O) shows 0.25 which is the lowest friction coefficient value than other orientations. (P-O)orientation of GFRP gave higher wear rate at maximum speed test in comparing to normal orientation.
