| Summary: | Natural fibers are gaining progressive account as a renewable, environmentally acceptable,
and biodegradable reinforcing fibre which combine acceptable mechanical properties with
a low density. The utilization of biomass (lignocelluloses) for the processing of novel
composites has attracted growing interest because of its eco-friendly and renewable nature.
The major challenge for natural fibre composites is their inherent poor adhesion between
fibre and the matrix. In this study the lignocelluloses were treated with alkaline peroxide to
remove lignin. Treatment time, temperature and concentration were optimized on the basis
of removal of noncellulosic compound. The non-cellulose and celluloses fibres were
blended in different ratios up to 50 wt% with polypropylene (PP) matrix using Twin-screw
extruder. Samples were prepared by using injection molding machine and tested using
tensile, flexural and impact tester. It was found that the mechanical properties were
improved by the alkaline peroxide treatment of fibre. Also, elimination of lignin contents
of fibre strongly influenced on the properties of polypropylene composite which was
evaluated by using Scanning Electron Microscope (SEM) and Fourier Transform Infrared
Spectrophotometry (FTIR). |
