The Effect of Treatment of Coconut Fiber with Liquid Smoke on Mechanical Properties of Composite

This study aims to determine the effect of liquid smoke treatment on tensile strength single fiber and Coconut (CF) Reinforced Composite. The research method is Immersion with heating. First treatment, CF was immersed in for 1, 2, 3 hours, then dried 1 hour at a temperature 40 degrees Celsius. Next, test carried out Universal Impact Test Machine composite impact strength. results showed that TP, P1J, P2J, P3J 51.357 MPa, 79.655 48.187 58.117 MPa. While 0.514 KJ/m 2 , 1.385 1,085 2,128 . immersion can increase fibers, where 1-hour has greatest value. In contrast, composites increased largest soaked could be an alternative improve mechanical properties CF.
