Abstract
Natural fiber reinforced polymer composites have raised their potential in different fields due to their high strength to weight ratio, abundantly available in nature and bio-degradable characteristics. The aim of present study is to familiarize the mechanical characteristics such as tensile properties and buckling strength of treated and untreated bamboo/nettle fiber reinforced epoxy hybrid composites. Also volume fraction of fiber and matrix was kept at 70%-30% in which 40% of nettle and 30% of bamboo fibers were used in this investigation. Bamboo and nettle fabrics were cut and immersed in 10% NaOH (sodium hydroxide) solution for 6 hrs to improve their surface morphology. Samples of several bamboo-nettle based natural hybrids were fabricated using vacuum bag technique where the layers of fabrics are placed alternately. Specimens are cut from the fabricated hybrid laminates for tensile test and buckling test as per ASTM standards. For tensile and buckling test samples were cut in the form of dog-bone shape and rectangular panels respectively. The tensile and buckling tests were performed using computerized UTM. The tensile and buckling values are computed for treated and untreated fiber composite to perceive the change in length. Result shows that alkali treated fiber composite has better tensile and buckling properties as compared to untreated fiber composites. This is due better interfacial bonding between fiber and matrix leads to increase of composite properties.
