Abstract

Wood is increasingly difficult to obtain due to the use of excess wood. Many efforts were made to replace wood, one of which was composite material. This study aims to determine the most optimal bending strength with the influence of variations in volume fractions and fiber orientation in hybrid composites with luffa fibers and hyacinth fibers. In making composites using the hand lay-up method with alaklization treatment on gambas and hyacinth fibers using 5% NaOH which is varied with the volume fraction used in this study with the ratio of resin: hyacinth: gambas is (60%:20% :20%),(70%:15%:15%), as well as (80% :10%:10%) and the orientation of the fibers with the arrangement of the luffa / hyacinth / luffa layer is (0°/ 45 °/ 90°), (0˚/45˚/0˚), (90˚/0˚/90˚). Bending testing was performed with ASTM D790 standard and hypothesis testing using the two-way ANOVA method. From the results of bending testing, the most optimal strength value was found, which was 43.33 N / mm2, where the value was not higher than the bending strength value in the multiplex, which was 17.53 N / mm2. Meanwhile, the results of hypothesis testing are that there is an influence on the volume fraction factor, the direction of fiber orientation and the interaction with bending forces.

Abstract

The purpose of this study is to determine the influence of volume fractions and orientation directions on the composite of gambas fiber and sugarcane fiber on bending strength. In this study, the variation in the volume fraction of resin, gambas fiber, and sugarcane fiber was (Resin 60%: Sugarcane Fiber 20%: Gambas Fiber 20%), (Resin 70%: Sugarcane Fiber 15%: Gambas Fiber 15%), and (Resin 80%: Sugarcane Fiber 10%: Gambas Fiber 10%) with the orientation direction of gambas fiber and sugarcane fiber 90°/90°, 90°/45°and 90°/0°. In this test, the bending test specimen was made according to the ASTM D 790-02  standard and the test result data were analyzed using the Two-Way ANOVA method assisted by Microsoft Exel software. This study showed that the volume fraction (Resin 60%: Sugarcane Fiber 20%: Gambas Fiber 20%) and the orientation direction of gambas fiber and sugarcane fiber 90°/90° have  the best bending strength  which is 48.33 (N/,) this value is higher than that of Multiplex with a bending strength value of  26,60 MPa.
