Jute reinforced polyester structures

Abstract Large diameter pipes and structures are manufactured with jute reinforced polyester resin. A modified filament winding machine is used to take the jute cloth on the rotating mold acting as a collapsible mandrel. The effect of calendering, fillers and poly(vinyl acetate) on jute reinforcing cloth and the results on the ultimate mechanical properties of the composite are studied. The effect of load during the curing of polyester and its effect on the strength of structure is reported. These findings are used in manufacturing of large diameter structures with improved mechanical properties.
