Tensile Properties of Polycarbonate-coated Natural Fabric Grewia tilifolia

The natural fabric from the tree of Grewia tilifolia was coated with polycarbonate. The tensile properties of both the uncoated and polycarbonate coated fabrics were studied. The tensile parameters such as maximum stress, Young's modulus and percentage elongation at break were determined using a Universal Testing Machine. The effect of alkali treatment and the polycarbonate coating on tensile properties was studied. The improvement in the tensile properties on polycarbonate coating was attributed to the filling up of the void regions of the uniaxial fabrics with polycarbonate facilitating continuity.
