| Abstract: | The aim of the present study is to investigate and compare the mechanical properties of raw jute and sisal fiber reinforced
epoxy composites with sodium hydroxide treated jute and sisal fiber reinforced epoxy composites. This is followed by comparisons
of the sodium hydroxide treated jute and sisal fiber reinforced composites. The jute and sisal fibers were treated with 20%
sodium hydroxide for 2 h and then incorporated into the epoxy matrix by a molding technique to form the composites. Similar
techniques have been adopted for the fabrication of raw jute and sisal fiber reinforced epoxy composites. The raw jute and
sisal fiber reinforced epoxy composites and the sodium hydroxide treated jute and sisal fiber reinforced epoxy composites
were characterized by FTIR. The mechanical properties (tensile and flexural strength), water absorption and morphological
changes were investigated for the composite samples. It was found that the sodium hydroxide treated jute and sisal fiber reinforced
epoxy composites exhibited better mechanical properties than the raw jute and raw sisal fiber reinforced composites. When
comparing the sodium hydroxide treated jute and sisal fiber reinforced epoxy composites, the sodium hydroxide treated jute
fiber reinforced composites exhibited better mechanical properties than the latter. |
