Role of Two Stage Wet Layup Manufacturing Method to Fabricate and Test Chemically Treated Dora Hemp Particulate FRP Composites

Abstract:

Increasing concern about the environmental pollution, clear understanding of uncertainty of petroleum products resulted in the utilization of eco-friendly materials. In the present work dora hemp natural fibre is made into particulate form through chemical treatment. Then it is reinforced at 3.98 wt % into the polyester matrix to fabricate the composite lamina by “Two Stage Wet Layup”. A special focus is made in describing the hand/wet lay-up procedure. The post cured and machined composite specimens as per ASTM procedures are tested to determine the mechanical properties. Dora hemp particulate composites have showed the tensile strength, modulus 12.57 MPa, 197.47 MPa respectively. In the bending load they have showed a flexural strength, modulus of 38.08 MPa, 1.78 GPa respectively. The composites under the impact load had shown impact strength of 1.38 kJ/m².
