TAILIEUCHUNG - Cotton bamboo fiber and properties of epoxy - cotton bamboo composites

Cotton bamboo fiber was prepared by steam explosion or mechanical method. Both methods included treated step in NaOH 1 N solution and the treated time was studied. The parameters of cotton fiber have been studied. The results of morphology and mechanical properties showed that the optimum treated time was hours for the explosion-cotton fiber and 2 hours for the mechanical-cotton one. | Journal of Chemistry Vol. 45 5A P. 176 -181 2007 COTTON BAMBOO FIBER AND PROPERTIES OF EPOXY - COTTON BAMBOO COMPOSITES Received 16 August 2007 TRAN VINH DIEU NGUyEN THI THUy AND NGUyEN ANH HIEP Polymer Centre Hanoi University of Technology summary Cotton bamboo fiber was prepared by steam explosion or mechanical method. Both methods included treated step in NaOH 1 N solution and the treated time was studied. The parameters of cotton fiber have been studied. The results of morphology and mechanical properties showed that the optimum treated time was hours for the explosion-cotton fiber and 2 hours for the mechanical-cotton one. Cotton fiber reinforced epoxy composites PC have been developed with varying fiber content. Tensile and bending strength with variation of fiber content have been studied and they were found to be maximal for the fiber content of 38 wt . With the same fiber content the properties of the explosion-cotton composites were higher than those of the mechanical-cotton composites. For example tensile strength was MPa and showed higher than that of mechanical-cotton composites bending strength was MPa and showed 12 higher than that of mechanical-cotton composites. Keywords Bamboo epoxy composites cotton. I - INTRODUCTION Although bamboo is extensively used as a valuable materials from times immemorial because of its high strength and low weight the studies on this fiber reinforced plastics are meager. Jindal 1 has reported the development of bamboo fiber reinforced plastic composites using Araldite Ciba-CY 230 resin as matrix. A. Varada Rajulu and et al. 2 has reported the chemical resistance and tensile properties of short bamboo fiber reinforced composites using Araldite Ciba-LY 5052 epoxy resin. In the present work the cotton fiber and properties of epoxy-cotton bamboo composites have been developed. II - MATERIALS AND METHODS 1. Materials a Matrix resin Epoxy resin Ruetapox CY 160 with density g cmI 3 and epoxy group .
