Mechanical properties of filled high density polyethylene

Mechanical properties of (HDPE M624) with three filler (inorganic and organic) composites were assessed with respect to the effect of the filler content. The filler varied from (5% to 25%) by weight in the composite. Obvious improvement in the mechanical parameters was recorded depending on the filler type and mesh size. The mechanical properties of loaded compressed sample have been evaluated through several parameters concerning the elastic deformation based on measuring the load–elongation characteristics.The behavior of stress–strain curve was analyzed in terms of cold drawing model. No experimental difficulties appeared at any mixing ratio, and these difficulties were due to the separation in phase which makes the sample possible for processing in the normal extruders.
