in this study some of the important properties of experimentally manufactured wood plastic composites wpc were determined. specimen having 60% and 80% particle and fibre of radiata pine pinus radiata were mixed with polypropylene plastic and four different additives, namely struktol tr 016 which is coupling agent, ciba anti-

actually, the finds of this study are in agreement to english and falk 1996 , which showed that polyolefins and wood plastic composites have higher density and lower flexural strength and modulus of elasticity stiffness than southern pine and douglas fir; and also in agreement to benthien and thoemen 2012 , which related that wood-plastic composites panels have higher specific weight than wood-based panels. in this sense, the specific properties values calculated in this study indicates
properties of the composites did not differ significantly from those of composites with virgin industrial wood particles used for manufacturing particleboards. moreover, these properties were comparable with the properties of typical wood plastic composites with wood flour.
abstract. wood plastic composite wpc is a composite material made from sawdust and plastic as polymer bonding, that used in a variety of structural and non-structural applications. nowadays, in indonesia wpc is made from sengon sawdust and recycled hdpe plastic. this research was conducted in order to investigate the physical
mechanical and physical properties of the panels manufactured from combination of plastic and wood material and fiber with addition of various types of chemicals are shown in table 3. average moe value of the samples containing 60% and 80% wood fiber without having any chemicals was found 2109 mpa fig. 6 .
specific gravity is one of the very fundamental properties of wood and timber. all types of wood have specific gravity below 1. the hardwoods have a specific gravity ranging between 0.7 to 0.9 whereas in most of the softwoods it lies below 0.7. hardness and strength of wood depend to a great extent on its density.
