Analysis of Mechanical Properties of Hybrid Composites of Pecan Shell and Bamboo Fiber Using Polyester Resin

Abstract

This study aims to determine the tensile strength and bending strength of composite materials composed of a Mixture of Pecan Shell Powder, Bamboo Fiber Powder, and Polyester Resin, with variations in weight ratio. In the tensile test, increasing the bamboo fiber powder content reduced tensile strength; the highest tensile strength was at 35CK%-15SB%-50RP%, with an average tension of 28.74 N/mm² and an average Strain of 2.857%. In the 25CK%-25SB%-50RP% comparison, the average voltage was 24,444 N/mm² and the average strain was 2,308%, and the smallest tension value was at 15CK%-35SB%-50RP%, with an average tension of 22,736 N/mm² and an average strain of 2,857%. Then for Bending testing,  it showed that the effect of adding Pecan Shell Powder and bamboo in a balanced manner had the highest Voltage value, the largest voltage was at a ratio of 25CK%-25SB%-50RP% with an average voltage value of 47,460 N/mm² and an average Deflection of 10,578 mm, Then at a comparison of 35CK%-15SB%-50RP% with an average voltage value of 45,139 N/mm² and an average Deflection 10.222 mm, and at a ratio of 15CK%-35SB%-50RP% with an average voltage value of 41.303 N/mm² and an average Deflection of 10.620 mm. Overall, this study provides an overview of the effect of the addition of Pecan Shell Powder and Bamboo Powder to the Specimen.
