Abstract

This study aims to determine the tensile strength and bending of coconut fiber filter composites combined with coconut shell epoxy resin powder. The material used is epoxy resin, coconut filter fiber with 1 mm fiber length, coconut shell powder. The coconut filter fiber used was treated with NaOH for 1 hour. The
composition used is 60% Resin: 25% Fiber: 15% Coconut shell powder, 60% Resin: 20% Fiber: 20% Coconut mixed powder, 60% Resin: 15% Fiber: 25% Coconut shell powder. The procedure for making composites refers to the ASTM D 638-01 standard for tensile tests and ASTM D 709-02 for bending tests. The results showed that the highest tensile strength was in the variation of volume fraction of 60% Resin: 15% Fiber: 25% Coconut shell powder was 6.34209333 N / mm2, and in the variation of volume fraction 60% Resin: 25% Fiber: 15% shell powder coconut has the lowest tensile strength value which is
4.18271666 N / mm2. while for bending testing the value of the greatest bending strength is found in variations of 60% Resin: 15% Fiber: 25% Coconut shell powder is 6.852063333 N/mm2 and the lowest
bending strength value is in the volume fraction% Resin: 25% Fiber: 15% powder coconut shell which is 4,712313333 N/mm2.
