Novel Hybrid Composites to improve structural performance of a Compact Electric Utility Vehicles Chassis
Resumen
Lightweight design is becoming increasingly important in various industries, particularly in aerospace, wind energy and automotive applications. Fibre-reinforced composites are attracting more interest for these weight-sensitive applications since their excellent stiffness and strength are combined with a low density. Unfortunately, the high stiffness and strength of these materials come at the expense of their limited toughness. The failure of the current composites is usually sudden and catastrophic, with no significant damage or warning. To ensure safe operations, currently a much greater safety margin is applied for composites than for ductile materials, reducing the benefits. Given these limitations of currently available high-performance composites, materials that fail in a pseudo-ductile manner are of exceptional interest and could potentially offer a notable increase in the scope of applications. This project has the main objective of exploit novel hybrid composites with pseudo-ductile behaviour in Compact Electric Utility Vehicles Chassis. Achieving gradual failure and pseudo ductility may help to the structure of the vehicle to maintain functionality even when it is overloaded, improving safety, reducing the weight and therefore increasing the autonomy of the batteries. The layups which will be proposed in this project will be implemented in the critical zones of the chassis which according to previous analyses are located in the joints supporting the suspension system of the vehicle. The novel pseudo-ductile hybrid composites layups will replace the metal inserts proposed initially in the chassis, which represent further benefits in terms of manufacturing costs, strength, weight and reducing discontinuities of the material. For the scope of this work, the high-performance hybrid composites layups will be analysed under tensile and bending loads. For this end, the materials will be tested using filled holes samples under tensile loads and three points bending tests, additionally finite element modelling will be proposed to understand the failure mechanisms.
