| dc.description.abstract | Bagasse fiber (BF) can be utilized as a reinforcement on composites especially because it is
environmentally friendly and comes from renewable resource. In this case, composites use chooped
type fibers and manufacturing processes with hand layup method. The volume fraction of unsaturated
polyester (UP) as a matrix fixed at 60%, and the fraction of BF and SCG filler varied by 0:40, 10:30,
20:20, 30:10, 40:0. In the application of composite panels, mechanical properties become the main
focus in mixing beside to obtaining other characteristics. Addition of spent ground coffee particles
(SCG) which decreases the tensile and flexural properties of composites, can be recovered by adding
bagasse fiber. The best fraction composition occurred at 10:30 (10BF30SCG60UP), which increased
the tensile strength composite (40SCG60UP) by 35.88% and the bending by 14.97%. Eventually, with
the cheap, simple method and utilization of industrial waste show the successful experiment to produce
stronger and more useful material. | en_US |
