STUDY ON TENSILE AND FLEXURAL PROPERTIES OF RECYCLED HIGH DENSITY POLYETHELENE/SAWDUST COMPOSITES

Plastic lumber is a wood plastic composite and usually made from recycled material. It is composed of recycled High Density Polyethylene (r-HDPE) and wood waste known as saw dust. The goal for this project is to evaluate the tensile and flexural properties of r-HDPE/sawdust composites with variou...
