Investigation of bio degradable natural fibers reinforced hybrid composites for aircraft structures

Abstract

Nowadays, composite materials are used in many applications as a replacement for conservative material. As a result, the development of industrial technologies, to track the development of resourceful material structures, an alternative is compulsory. The focus of the current study is to explore and compare the mechanical properties of Sisal and banana fiber reinforced epoxy hybrid composites. For better results in mechanical properties, Sisal fibers are hybrid with banana fibers. The sisal and banana fibers with various weight ratios like 0%, 4%, 8%, 12%, 16%, and 10% (Banana fiber) 5% (Sisal fiber) is mixed with the epoxy resin matrix. The hardness, tensile, flexural, impact tests are carried out using fabricated composite specimens. This research work is evidence that the mixture of sisal and banana fiber epoxy composites around 22% by results in weight level increased mechanical properties and decreased moisture absorption properties. These methods of improving the bonding among the reinforcement and matrix, the effect of orientation, the effect due to the size of the fibers, and the percentage reinforcement have been studied.
