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 conscious
consumer environment to preserve nature. In this research used kenaf fiber mixed with glass fiber for material of civil
structure that is house ceiling material like plywood. The main objective of this research is to develop composite blend
of polyester reinforced polyester fiber into home ceiling material by using composite sheeting. In this research has used
the 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 mercerization
method in order to remove lignin and oil contained in kenaf fibers. Prior to the mechanical testing of the composite
blend of kenaf-glass fiber is first tested physics by giving a heating temperature of 40oC and immersed in rain water up
to 15 days. Testing of flexure test and impact test of each with ASTM D790 and ASTM D 6110 standards. As a
comparison in this test is also used plywood for physical tests and mechanical tests. The results obtained that the
composite hybrid material kenaf glass and triplex before soaked visible mechanical strength hybrid composite kenaf
glass better than plywood. However, after immersed and heating, it is generally seen that the material will decrease the
mechanical strength of the material either by flexure test or by impact test.
