Polycaprolactone (PCL) based polymer composites filled wheat straw flour

In this study, polycaprolactone (PCL) based polymer composites were manufactured through injection moulding machine. Polycaprolactone (PCL) and wheat straw flour was used  as polymer matrix and organic filler respectively. The effects of wheat straw flour loading on the mechanical properties of the manufactured composites were investigated. The thermal behaviors (TGA and DSC), mechanical properties (tensile, flexural and impact strength), of manufactured composites were determined. According to test results the addition of  wheat straw into PCL matrix reduced tensile strength, elongation at break and impact strength of composites while improving the tensile, flexural strength and flexural modulus.
