Physical and Mechanical Behaviour of Polypropylene Composites Filled with Chitosan Filler
AbstractAbstract In this experimental study, polypropylene (PP) based composites filled with up to 30 wt% chitosan mineral filler, were prepared by extrusion and injection molding. Chitosan filler, with weight percentages varying between 10 and 30 wt%, were added to polypropylene polymer matrix. Uniaxial tensile, impact, hardness and three-point bending tests were used to examine the effect of chitosan filler addition on the mechanical behavior of polypropylene. Tensile strength, tensile modulus, elongation at break, hardness, impact energy and flexural strength and flexural modulus were obtained. The results showed that the tensile strength, flexural strength, tensile and flexural modulus of polypropylene composite material increased with the increment of filler weight ratio while the impact strength and maximum elongation values decreased with the increase in chitosan filler weight ratio.
