Abstract

Abstract: The superior properties of the fibres in comparison with the conventional materials have made them as favorite for using as the enhancement material in the polymer composites. Without compromising on the physical and mechanical properties, there is an increasing trend of synthesizing composites. This paper presents the characterization of hybrid composites with the combination of dual resins (epoxy -polyester) prepared by using hand lay-up technique. Hybrid composites are prepared by keeping 50% weight of dual resin and 50% of reinforcement. Dual resin composites are prepared by varying the weight fraction of epoxy—polyester hybrid resins in the percentages of 80E-20P, 70E-30P, 60E-40P, 50E-50P to characterize their mechanical properties. Among the all jute-glass reinforced hybrid composites, jute-glass fibre reinforced 50%E–50%P hybrid composite (50E50PHC) has the highest average tensile strength of 128.047 N mm −2, 80%E-20%P hybrid composite (80E20PHC) has the highest impact strength of 0.1151 J mm −2 with energy absorption of 4 J, 60%E–40%P hybrid composite (60E40PHC) has highest average flexural strength of 297.7 N mm −2 with the deflection of 6.12 mm. SEM morphology under tensile, flexural and impact loading are also presented and images reveal that strength of the composite has increased with the addition of glass fibre.
