Study Of Mechanical Properties Of Wheat Straw Fiber Reinforced Polystyrene Composites
In this study, the effect of the wheat straw with different fiber concentration (5 to 25% by weight) on the
mechanical properties of the polystyrene composites were studied. The polystyrene composites of wheat straw were
prepared by Haake Rheocord 9000 twin screw extruder machine. The standard test specimens were molded on
compression moulding machine. Mechanical properties were determined using these test specimens. It was found that with
the addition of wheat straw as filler in polystyrene composites, tensile strength, impact strength and hardness are found to
increase with increase in wheat straw concentration.
