Abstract

The study presents a frictional analysis on woven and unidirectional glass fibre-reinforced epoxy composite materials, fabricated using vacuum infusion method at varying hardener/resin ratio. Tensile tests are conducted using a universal testing machine to determine the tensile modulus of elasticity for the tested materials while frictional characteristics of the these materials are measured using a pin-on-disk tribometer. It is found that the tensile modulus of elasticity for woven and unidirectional glass fibre-reinforced epoxy composite materials reduce for hardener/resin ratio with higher phr values. On the other hand, reducing friction force is measured for these materials when phr values are increased. By correlating tensile modulus of elasticity with frictional properties, it is shown in the present study that the coefficient of friction for woven and unidirectional glass fibre-reinforced epoxy composite materials reduces with lower tensile modulus of elasticity (higher phr values). The lower coefficient of friction observed is believed to be influenced by the larger deformation capacity of a more hardener rich epoxy based composite system.
