ANALISI KEKUATAN MEKANIK ANTARA KOMPOSIT HYBRID SERAT KENAFGELAS DENGAN TRIPLEKS UNTUK APLIKASI PLAFON RUMAH

Abstract

Today there has been much increased interest in the use of composites by using natural fibers because the consciousconsumer environment to preserve nature. In this research used kenaf fiber mixed with glass fiber for material of civilstructure that is house ceiling material like plywood. The main objective of this research is to develop composite blendof polyester reinforced polyester fiber into home ceiling material by using composite sheeting. In this research has usedthe composition of fiber kenaf glass in the form of a mat with a ratio of 65:35 (based on weight/m2). Prior to composite,kenaf fibers were immersed with water with 6% sodium hydroxide (NaOH) dissolved for 3 hours using a mercerizationmethod in order to remove lignin and oil contained in kenaf fibers. Prior to the mechanical testing of the compositeblend of kenaf-glass fiber is first tested physics by giving a heating temperature of 40oC and immersed in rain water upto 15 days. Testing of flexure test and impact test of each with ASTM D790 and ASTM D 6110 standards. As acomparison in this test is also used plywood for physical tests and mechanical tests. The results obtained that thecomposite hybrid material kenaf glass and triplex before soaked visible mechanical strength hybrid composite kenafglass better than plywood. However, after immersed and heating, it is generally seen that the material will decrease themechanical strength of the material either by flexure test or by impact test.
