ANALISIS PENGARUH JUMLAH LAPISAN PAPAN PARTIKEL SERBUK KENAF TERHADAP KEKUATAN SIFAT FISIS DAN MEKANIS
The purpose of this study to make laminates particleboard from kenaf powder and see the effect of the number of layers of laminate particleboard on the strength of physical and mechanical properties. The number of laminates made from this research consists of one layer, two layers and three layers. The composition of the filler and matrix used in the manufacture of particleboard consisting of kenaf fiber and epoxy resin is 30%:70% with a ratio of percent by weight. The process of compaction of particle board using the cold press method with a pressure of 30 Bar. Tests of physical properties carried out in this study include density and water absorption. Testing of mechanical properties in this research includes tensile strength test and impact strength test. The results of the density test ranged (0.79gr/cm3-0.86gr/cm3), the results of the water absorption test ranged (4.11%-3.28%). The results of the tensile strength test ranged from (12.99kgf/cm2-118.77kgf/cm2) and the impact strength values ranged (1.03 J/cm2-2.87J/cm2). The results of the physical properties test, namely the density test and water absorption, have met the standards of SNI 03-2105-2006, namely high density particleboard and water absorption with a water content value of <5%. The results of the mechanical testing, namely the tensile strength test of this study also met SNI 03-2105-2006. The results of this study indicate that the greater the number of layers in the manufacture of particleboard, the greater the value of the physical and mechanical properties of the particleboard.
