Renewable resources such as natural fillers in the field of particles reinforced materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating environmental friendly materials. Nowadays, natural fibers reinforced composites exhibit the superior mechanical properties than synthetic fiber reinforced polymer composites due to its inherent properties. Natural fiber reinforced composites are renewable, biodegradable, environment friendly, light weight material when compared to the synthetic fiber reinforced composites. In this investigation, composites high density polyethylene and uncarbonized and carbonized waste corn husk powder were prepared. The effects of uncarbonized and carbonized waste corn husk powder ratio on the physical and wear properties of the polymer composites are presented. Corn husk powder, in four different concentrations (10, 20, 30 and 40 wt %), were added to HDPE to produce composites as well. The physical properties, including the Vicat softening point, heat deflection temperature, melt flow index, moisture content and limit oxygen index of the composites were investigated. On the other hand, the wear properties of the composites were investigated. The structure of the composites were investigated by scanning electron microscopy and compared to physical and wear properties as a function of uncarbonized and carbonized waste corn husk powder content. Key words: High density polyethylene, corn husk, physical properties, wear, polymer composites.
