Mechanical properties of ethylene-octene copolymer (EOC) - lignocellulosic fillers biocomposites in dependence to filler content

The mechanical properties of biocomposites based on ethylene-octene copolymer were studied. The aim of present work was to investigate the mechanical properties of composites based on ethylene-octene copolymer (EOC) in dependence to type of the filler, filler content and trade mark of EOC. Addition of fillers (wood flour or seed flax straw) decreases elongation at break and decreases unsignificantly tensile strenght of examined copolymers. Particles of filler increase the toughness of polymer chain, which leads to decline of elongation at break. Biocomposites with wood flour had higher tensile strength and elongation at break than the composites with flax straw.
