Study the Effect of Mill Scale Filler on Mechanical Properties of Bidirectional Carbon Fibre-Reinforced Polymer Composite
In this study, the effect of mill scale as the filler with different weight percentage in carbon fibre reinforced polymer composites is investigated. The composites are fabricated with 0, 5 and 10 wt% of mill scale, respectively, using hand lay-up method. The mechanical performance of the composites is evaluated by tensile test, flexural test, inter-laminar shear stress and micro-Vickers hardness test. It is observed that incorporation of mill scale in composite increases the tensile strength by 2.40% (5 wt%) and 4.73% (10 wt%); flexural strength by 35.34% (5 wt%) and by 17.78% (10 wt%); ILSS by 44.40% (5 wt%) and 41.45% (10 wt%); hardness by 14.70% (5 wt%) and by 25.49% (10 wt%). The results reveal that mill scale as filler in composite significantly affects the mechanical properties. This work may provide a meaningful way to modify the conventional manufacturing methods in various industrial applications of CFRPs.
