摘要：Different amount of raw Ketuki powder (average diameter: 60 – 120 ?m) was mixed with the thermoplastic polymers such as ethylene-1–octene copolymer (EOC) and isotactic polypropylene (iPP). The melt mixing was performed using an internal mixture and resulting composites were studied for the effect on morphology and mechanical behavior using electron microscopy, tensile testing and thermogravimetric analysis (TGA). The microscopic results showed that the polymer matrix is not compatible with filler resulting in worsening of mechanical properties especially in case of the iPP-based composites. For the EOC composites the rubbery nature of the matrix material remains still visible. The TGA analysis revealed slightly worsened thermal stability of composites, while tensile properties were found to be deteriorated as well.
