Development and Properties of Hybrid Composites

Abstract

The Flexural and tensile properties and Scanning electron Microscope analysis of Aramide/Onion/Glass fibers Reinforced Epoxy Hybrid composites were studied. The effect of alkali treatment of the Aramide/Onion/Glass  fibers  on these properties was also studied. These properties found to be higher when alkali treated glass fibers were used in the hybrid composites. The elimination of amorphous hemi-cellulose with alkali treated leading to higher crystallinity  of the Aramide/ Onion/Glass fibers with alkali treatment may be responsible for these observations. The author investigated the interfacial bonding between Aramide/Onion/Glass reinforced epoxy composites. The effect of alkali treatment on the bonding between Aramide/Onion/Glass composites was also studied.
