Composite structures produced were containing 3 % and % 6 waste cotton fibre. <span style="mso-spacerun: yes;">  </span>100% PP with no cotton fibre was also produced. All samples were tested <span style="mso-spacerun: yes;">   </span>in terms of tensile strength, elasticity modulus, yield strength, elongation, Izod impact strength, hardness and MFI (Melt Flow Index). Increasing the cotton waste ratio in PP polymer composite; increases the elasticity modulus, yield strength and tensile strength, and decreases the <span style="mso-spacerun: yes;">  </span>% elongation and izod impact strength, but in hardness values however considerable changes were not observed. </span> </p> <p class="MsoNormal" style="margin: 0cm 0cm 0pt; text-align: justify;"> <span style="font-size: small; font-family: Times New Roman;">  </span> </p> <p class="MsoNormal" style="margin: 0cm 0cm 0pt; text-align: justify;"> <span style="font-size: small; font-family: Times New Roman;">Key Words: Waste cotton, PP, composite materials, polymer composite. </span> </p>}, number={2}, publisher={Gazi University}
