 5% with VNAOH alkali treatment of DCFS for 90 minutes resulted in improved cellulose content, decreased hemicellulose and lignin contents, increased crystallinity index, tensile strength, thermal stability and surface topography. The optimally treated DCFS were found to be suitable as reinforcement material in polymer composites and their weight percentages were prepared by hand layup and compression molding methods. The mechanical testing of the prepared composites was conducted according to ASTM standards. This article was authored by P. G. Baskaran, M. Katharason and P. Pandya Rajan.
