Sand/low density polyethylene composite samples were prepared using injection molding. The effect of some processing and structural parameters on the flow and fracture behavior of the prepared samples was investigated. Typical processing parameters were melt and die temperatures. The investigated structural parameters were sand particle size and sand content.

Higher melt and die temperatures decrease the tensile strength and the modulus of elasticity for the various sand contents investigated, meanwhile, the ductility and toughness increase. Sand addition increases the tensile strength and the modulus of elasticity, as long as the sand size is smaller than 400 μm. Larger particle size weakens the structure. A maximum in the tensile strength, ductility and work done to fracture is observed for samples with a particle size of 400 μm. Adhesion and interlocking are responsible for the strengthening effect below 400 μm, while dewetting and interfacial friction are responsible for the reduced tensile strength and modulus of elasticity above 400 μm.
