Effect of cenosphere on mechanical properties of bamboo–epoxy composites

Cenosphere is a ceramic-rich industrial waste produced during burning of coal in thermal power plants. This study deals with the effect of cenosphere as particulate filler on mechanical behaviour of natural fibre composites. The natural fibre composite consists of bamboo fibre as reinforcement and epoxy as matrix. The bamboo fibre is treated with alkali to improve its surface properties. The conventional hand lay-up technique is used to prepare different composite specimens. Twenty numbers of different composite specimens are prepared with varying number of laminae and filler content. The samples are analysed for their mechanical properties to establish the effect of varying filler content and the number of laminae. It is found that the mechanical properties are significantly influenced by addition of this waste-based ceramic filler.
