Abstract

Abstract: This paper presents the effect of Cloisite-15A and OMIB nanoclays in vinylester/glass on their mechanical, thermal and fire retardation behaviour containing percentage amounts of nanoclays in vinylester utilising the blend of ultrasonication and twin screw extrusion. Nanoclays/vinylester/glass specimens have been fabricated by using hand lay-up technique. XRD outcome of Nanoclays/vinylester gel coat confirmed exfoliation of nanoclay as much as 4 wt.% nanoclay loading. Glass transition temperature of Nanoclays/vinylester improved monotonically with increase in nanoclays loading. Best tensile strength, Interlaminar shear strength, Flexural Strength and Impact strength of vinylester/glass increases as much as 4 wt.% loading with the addition of OMIB however lowered when compared to Cloisite-15A. Limiting oxygen index of vinylester/glass specimens reduced monotonically with the addition of Cloisite-15A and OMIB.
