Bamboo Composite Compressive Strength With Three Layer Configuration

Abstract

The use of composite materials in the automotive industry aims to create new material that have advantage of good mechanical properties, environmentally friendly and cheaper. Composite is a combination of two or more materials that have good physical properties and good mechanical properties. Reinforcement materials commonly used in polymer composites are natural bamboo strips can be used as reinforcement materials and matrix used was epoxy resin polymer. The research phase began with the manual cutting of bamboo into bamboo strips using a knife with a thickness of 0.5-0.8 mm and width of 4.0-6.0 mm bamboo strips. Bamboo strips were given 5% alkaline treatment for 72 hours, after alkaline treatment is complete the bamboo strips are washed with clean water flow and dried at room temperature for 48 hours. Reinforcement that is used is plain weave type using bamboo strips. The composite manufacturing process uses the hand lay-up method. The configurations of orientation angle that is used are 0°/0°/0°; 0°/45°/0°; 0°/90°/0°. Compressive test with ASTM D3410/D3410M-16 and observe microstructure using SEM (Scanning Electron Microscope). Composite with configurations of orientation angle of 0°/0°/0° have the highest average impact value of 0.216 J/mm2 and an average compressive strenght of69.740 MPa with average modulus of elasticity of 41.660 GPa. The result of observe using SEM (Scanning Electron Microscope) are given initial signs of specimen damage, delaminate and buckling.
