Pengaruh Fraksi Volume dan Orientasi Serat Pada Komposit Hibrid Berpenguat Serat Gambas serta Eceng Gondok Terhadap Kekuatan Bending

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