摘要

In this study, mechanical and physical properties of high density polyethylene (HDPE) based composite filled with two different lignocellulose fibers were investigated. Polymer composite were prepared by using HDPE as a polymer matrix and sunflower seed husk (Helianthus annuus L.) or chaste tree (Vitex negondu L.) as lignocellulosic filler at 15% and 30% loading. The effect of filler types and concentration on the mechanical properties of high density polyethylene (HDPE) based composites were investigated. Pellets were first manufactured through single screw extruder. Then, manufactured pellets were turned into composite samples by using injection molding machine. Tensile, flexural and impact properties were determined according to ASTM D638, ASTM D790 and ASTM D256, respectively. Addition of chaste tree fiber to thermoplastic composite provided better mechanical and physical properties compare to sunflower husk. All manufactured groups provided necessary values required by the ASTM D 6622 standards.
