Abstract: In recent years, textile waste fiber-reinforced thermoplastic polymer matrix composites have gained commercial success in different applications. In this study, polypropylene matrix based composite structures were produced by using waste denim fiber at different ratios (5 and 10 %) and conditions (with and without moisture). The mechanical, thermal, chemical and morphological properties of the composites were characterized. The results indicated that after removing moisture, the flexural strength and the flexure modulus of the composites improved with increasing fiber percentage, whereas better tensile properties were obtained at lower fiber content. The highest tensile strength was obtained for 5wt% dry denim fiber-pp composites. The surface morphology of the fracture surfaces of the tensile specimens, examined by a field emission scanning electron microscope, revealed the presence of microvoids. The infrared spectra of pp-denim fiber composites were taken and the characteristic peaks were studied. The lower thermal stability of the produced composites were confirmed by Thermo Gravimetric Analysis (TGA).
Keywords: Waste denim fiber, polypropylene (pp) resin, composite, moisture.
