| Abstract: | Uses of natural fibers as reinforcement in polymers have
gained importance in the recent years due to the eco-friendly nature. This
paper deals with the mechanical properties of the composites made up of palmyra
fiber waste [pfw] and the pfw/glass fiber hybrid composites. Composite plates
were prepared with 30%, 38%, 45%, 50%, 58%, 65% and 70% wt of fiber waste.
Tensile, flexural, shear and impact properties were studied. Composites with
58-65-wt% fibers showed marginal improvement in flexural strength. Tensile
strength was decreased and there was considerable improvement in shear and
impact properties than that of resin. The properties of the natural fiber reinforced composites can
be improved by hybridizing with high strength synthetic fibers such as glass.
In this study, the palmyra fiber waste was hybridized with glass fiber in the
polyester matrix. Samples were prepared by sandwiching the fiber waste between
chopped strand glass fiber mats by varying both glass fibers and waste material
content, keeping total fiber content as 60% by weight. Specimens were cut as
per ASTM standards and tested in Instron universal testing machine. Mechanical
properties of the composites were found to be increased with increase in the
amount of glass fiber in the hybrid. Hybrid composites containing 48% waste,
10% glass fiber showed good reinforcement effect than the composites reinforced
with 11 wt % glass fiber. The resin used was isophthalic roof light resin, the
catalyst and accelerator were methyl ethyl ketone peroxide (MEKP) and cobalt
napthanate, respectively. |
