Pembuatan dan Karakterisasi Papan Komposit Polimer dari Campuran Polipropilena, Serat Sabut Kelapa, dan Kulit Tanduk Kopi

Abstract

Research about manufacture and characterization of polymer composite board utilized a mixture of polypropylene, coconut fibers, and parchment of coffee bean had been done. This study aimed to determine the effect of variations coconut fibers and polypropylene to polymer composite board characteristics. Comparison of polypropylene, coconut fibers, parchment of coffee bean, and maleic anhydride with each composition are (100 : 0 : 0 : 0) gr, (90,5 : 0 : 5 : 4,5) gr, (89,5 : 1 : 5 : 4,5) gr, (88,5 : 2 : 5 : 4,5) gr, (87,5 : 3 : 5 : 4,5) gr, which the function of maleic anhydride as a catalyst. The manufacture of polymer composite board used refluxtion method which adding of xylene 300 ml as a solvent. Characterization testing performed included physical test (density and water absorption) and mechanical test (impact, tensile, and flexural). The results showed that the characteristics of polymer composite board were influenced by coconut fibers and parchment of coffee bean composition.
