The enhancement of composite strength by addition of fillers especially industrial
waste attracts more attention. In this article, the effect of redmud (aluminium industry waste)
as a secondary reinforcement on Palmyra fruit fiber and Palmyra fiber waste as primary
reinforcement along with unsaturated polyester has been analyzed. Hardness, Tensile and
Impact property of the Palmyra fibers with and without redmud have been reported. Palmyra
fiber (both fruit and waste type) of length 30 mm and weight percentage of 50 % has been
taken for this study. Also redmud of different varying weight percentages 10 %, 20 %, 30 %,
and 40 % respectively taken to study its effect. It is noted that the Impact strength increases
with more and more addition of redmud in both cases of fibers. The Tensile strength increases
for 10 %wt addition of redmud in the case of Palmyra fruit fiber and 20 %wt addition of
redmud for Palmyra fiber waste. The failure mechanism of the composites has also been
discussed by microscopic studies.
