Study of Mechanical Behavior for Tamarind Shell Powder and Coconut Coir Fiber Epoxy Composite for Aerospace Application
Now a days, the natural fibres from renewable natural resources offer the potential to act as a reinforcing material for polymer composites alternative to the use of glass, carbon and other man made fibres. Among various fibres, coir is most widely used natural fiber due to its advantages like easy availability, low density, low production cost and satisfactory mechanical properties. For a composite material, its mechanical behavior depends on many factors such as fiber content, orientation, types, length etc. Natural fibre composites NFC are gaining interest in manufacturing because they address some of the environmental problems of traditional composites use of non renewable resources, and large impacts related to their production and disposal. Since natural fibres are not yet optimized for composite production, it is crucial to identify the most appropriate applications, and determine the optimal fibre matrix ratio. Results from various experiments help identify the application with the largest reduction in environmental burden and show that the fibre matrix combination with the lowest environmental burden also has the best mechanical properties. Attempts have been made in this research work to study the effect of fiber loading and orientation on the physical and mechanical behavior of coconut fiber and tamarind shell powder reinforced epoxy based hybrid composites which is prepared by hand layup method with different weight proportions.
