Fabrication and Testing of Novel Aluminium Composite Panel and Analysis of Composite Panel for Impact Loads in Collision Environment for Four-Wheelers Automobile

Abstract

Impact loads from the crash of automobile always challenge the structural parts of the collided vehicles. Modern high – speed vehicles are subjected to high impact loads during accidents when the vehicle is accelerating at high speeds. This results in structural damage to the vehicle as well as passengers in the vehicle. In recent years, high-strength aluminum alloys have increasingly been used for building high-speed vehicles, and other types of weight-critical structures. In such structures, stiffened panels are the basic strength members. Composite panels can be used for the car body to reduce the weight of the vehicle and to increase the collision resistance. In this study, the aluminum composite panels with composite filled stiffeners are fabricated and tested experimentally under compression and impact loadings. Recycled ceramic powder, recycled steel flakes, and E - glass fiber mesh is taken as reinforcements and thermoplastic resins as matrix materials in the preparation stiffener filler composite. The composite panel specimens are fabricated and are tested experimentally under axial compression for collapse resistance.
