The objective of the thesis is to develop a new hybrid nano reinforced polymer composite which has good mechanical properties and was applied in automobiles. Based on the fact that polymer composite matrix is filled with nanoparticles makes it possible to improve mechanical behaviour of composite, the hybrid nano reinforced polymer composite is developed based on different orientations and in which the higher elastic properties were achieved in the multi-directionally oriented material. The requirement of the improvement of the vehicle such as fuel efficiency, better performance and the strength of the vehicle causes the industrial automobile manufacturers to develop new materials and restructure old ones and correctly choosing materials. In this study, the stiffness behaviour of Hybrid fibre reinforced polymer composite has been analysed considering the nano reinforcement. Stiffness is a resistance which an elastic body provides to deflection or deformation by an applied force. The results obtained concludes the fitness of material for usage. Considering the application of the developed material in an automotive structure, an automotive hood is modelled with developed material properties and it is analysed under crash condition. The material selection strategy for individual parts of the car body is the most critical and complicated process affecting many fields which bringing together technologists, manufacturers, materials experts, managers which economists, as individual parts of the car body have a major effect on total fuel usage, environment, drivability, service and, ultimately, total automobile health. The usage of composite materials in automotive materials improves the strength, weight reduction and recyclability of the material. In this research, hybrid composite is considered, in which carbon nanotubes are infused through which a better material property is achieved. Vehicle crash modelling using computer software has been an invaluable method for shortening vehicle construction time and reducing costs. It also impacts a car's crashworthiness enormously. This research talks about a car artificial crash test. The purpose of this study is to model a frontal impact accident and verify results, the developed material in which the weight reduction is achieved and also the material withstands crash conditions as the other materials. The study shows that the nano reinforced polymer composites have a better future in the production of automotive structures and can be utilised in better ways. |
