Development and comparison of tensile and compressive strength and percentage shrinkage of glass- jute hybrid fibre reinforced polymer composites

Abstract

Glass-jute hybrid fibre reinforced polymer composites were developed by using pultrusion process. In order to carry out these experiments, an experimental setup for pultrusion process was developed. Reinforcement of natural jute fibre and glass fibre was done in the developed composites. Unsaturated polyester resin as matrix and coconut coir ash, carbon black and egg shell ash as filler were used. The variation in tensile strength of pultruded Hybrid FRP composites were observed due to variation in weight percentage of coconut coir ash, carbon black and eggshell ash as filler. Filler’s weight percentage was variable while weight percentage of unsaturated polyester resin as matrix and glass and jute as fibre reinforcement were fixed. Single filler with variable percentage was used in the development of composite specimens with fixed weight percentage of matrix and fibres. Total fifteen hybrid composite specimens (samples) were developed, out of which carbon black, coconut coir ash and egg shell ash fillers have five samples of each with their variable weight percentage. Maximum tensile strength was observed 76 MPa in hybrid composite specimen namely hybrid composite specimen with 9% carbon black filler and maximum compressive strength was observed 99.44 MPa in hybrid composite specimen with 15% Eggshell ash as filler.
