In this experimental research; It has been studied to improve the properties of polypropylene grape stalk and paddy mixtures
by adding waste glass fiber. The potential of waste grape stalk and paddy to be a reusable material has created another
curious subject. Polypropylene grape stalk and paddy were mixed in a twin screw extruder to provide a homogeneous
mixture. Paddy; It is known as rice husk. Grape stalk-paddy was added to the PP at the rate of 20%. Glass fiber was added at
10-15% and 20% rates. Then the test samples were molded on the injection machine. Molded samples; Tensile, hardness,
impact, density and scanning electron microscopy tests were performed. By examining the results of the tests, the effects of
grape stalk-paddy and glass fiber amount on polypropylene were determined.
