Abstract
The main objective of this study is the improvement of the interfacial adhesion of RHF-polypropylene (PP) bio-composites through NaOH and acetic acid treated RHF. After manufacturing of untreated and NaOH and acetic acid treated RHF filled PP bio-composites, the effect on interfacial adhesion of bio-composites was investigated. Tensile strength of the bio-composites made from treated RHF with NaOH and acetic acid was higher than that of the untreated bio-composites. The RHF surface before and after NaOH and acetic acid treatment was clearly confirmed by scanning electron microscopy (SEM) micrograph. It was found that both treatments result in a removal of impurity materials of RHF surface by SEM micrographs. The chemical structures of untreated and NaOH and acetic acid treated RHF were confirmed by fourier transform infrared (FTIR). The crystallization structure and crystallinity of non-treated, NaOH and acetic acid treated RHF were investigated by wide-angle X-ray scattering (WAXS).
