| Abstract | The sustainable processing of recycled products requires veritable testing during quality control for commercial application. In this research work, mechanical (ASTM D3039), compression (ASTM D5467) and impact (ASTM A370) are utilized to observe the usability, diversity, and suitability of the developed polypropylene-postconsumer cotton fibers (PP-PCCF) composites for industrial applications. The cotton waste was ground using a grinding machine. The ground fibers were introduced to manufacture com-posites from 0 to 40% fiber loading variations. The fine cotton fibers and synthesized composites were characterized by scanning electron microscope before and after mechanical testing. The fiber length, diameter and area were in the range of 2.5 mm-5.5 mm, 12.5 mm-22 mm and 200.15 mm2-250.50 mm2, respectively. The engineering and design values were tensile strength (31.16 MPa-22.77 MPa), breaking strength (26.69 MPa-22.77 MPa), modulus of elasticity (2223.79 MPa-2770.77 MPa), and extension (17.48-3.21). Similarly, flexural strength, modulus, energy, and fracture force are also enhanced with an increase in fiber loading. The impact energies of pure polypropylene and PP-PCCF composites (with 10, 30, and 40% PCCF contents) were 50 kJ/m2, 48 kJ/m2, 43 kJ/m2, and 58 kJ/m2. The micrographs of PP-PCCF composites prove that the density of voids is enhanced with an increase in fiber contents. The PP-PCCF composites with 0%-30% fiber loadings showed minimum defects and were observed to be suitable for structural applications. On the other hand, the PP-PCCF composites with 30%-40% fiber loading are acceptable for environmental applications. (c) 2022 Kingfa Scientific and Technological Co. Ltd.
