Composite materials are produced synthetically with a matrix material and a filler or reinforcement to provide the desired properties. In composites, synthetic fillers are often preferred. Natural fibers and fillers, on the other hand, are now preferred over synthetic fillers. These materials can be found in polymer matrices as reinforcement and fillers. Composite materials made from natural materials are replacing traditional materials in the industry for many reasons, including easy processing, lightness, and low cost. In this study, the usability of pine wood sawdust and cotton together in polymer matrix composites was investigated. Pine sawdust is a product that emerges as waste, especially in the furniture industry. On the other hand, cotton has a wide area of use in the textile industry and is also obtained as a waste product. Recycled Polypropylene is used as a matrix material due to its intense use in industry. Pine sawdust was prepared using a sieve in the size of 0-250 microns. Since the waste cotton is in different sizes, it was cut to be 1 cm to have certain sizes. Composite materials were produced by adding pine sawdust and textile waste to recycled Polypropylene at different ratios. Composite samples were prepared by injection molding method. The physical properties of the samples such as tensile, impact, hardness and water absorption properties were investigated. SEM images of the fracture surfaces were analyzed. As a result of the study, it was evaluated that pine sawdust and waste cotton would be used in polypropylene-based composite applications.
