The present investigation focusses on the analysis of effect of notch depth and sea water ageing on the impact behaviour of glass fibre reinforced epoxy composites filled with graphite particulates as the secondary reinforcement. The laminates of epoxy composites with different compositions are developed by varying graphite filler in the volume proportion of 0%, 4% and 8% vol. The epoxy composites fabricated are subjected to ageing in water for different time durations of 50 h, 100 h and 150 h. The specimens subjected to ageing are tested for impact strength according to ASTM D256 at different notch depth varying from 1 mm–4 mm in steps of 1 mm. It is evident from the experimentation that increase in impact strength is obtained for epoxy composites with increase in addition of graphite filler. It is observed that sea water aged specimens with 4-mm notch depth have resulted in enhanced impact strength of about 51% compared to 1-mm notch depth. |
