Chemically
Treated Sacchurum as Reinforced for Polymer Composite |
This
work involves using Saccharum short fibers as reinforcement for
unsaturated polyester before and after chemical treatment for
fibers. The chemical treatment was done in NaOH solution with
different concentrations include 0.125, 0.25, 0.375, 0.5 and
0.625 M at room temperature. The prepared composites were
characterized by FTIR spectra to confirm the improvement of
interaction between reinforcement and matrix through the
reduction in hydrophilic groups. The investigation by FTIR
showed the improving of the adhesion between reinforcement and
polyester as matrix because of reduction of absorption the
water. The impact toughness was tested for polymeric composites
and the results indicated that the chemical treatment with NaOH
led to increasing impact energy due to increasing bonding force
between treated Saccharum fibers and matrix |
