Abstract Scope |
Epoxy based GFRP composites comprising of surface-treated polyethylene fibers (PE) and silanized nanoclay were processed through vacuum assisted resin infusion moulding with substantial improvements in impact strength. PE fibers were used owing to characteristics like good toughness, strength, resistance to chemicals, and light-weight. Nanoclay and PE fibers were subjected to surface treatments for improving compatibilization which was confirmed by FESEM-EDS and FTIR techniques. XRD/TEM analysis was used to determine morphology of nanoclay platelets. Reinforcement of pristine PE fibers decreased the mechanical properties owing to less compatibility among constituents of composite system. However, reinforcement of compatibilized PE fibers to GFRPs boosted the impact strength. GFRPs reinforced with maleic anhydride grafted PE fibers and silanized nanoclay provided maximum enhancement of 160% in impact strength over the base composite. FESEM micrographs identified the mechanisms causing improvement in impact behaviour. |
