ALUMINIUM HYBRID COMPOSITES APPLICATION IN AUTOMOTIVE INDUSTRY

Strict requirements that are put on mechanical constructions from the side of increase of manipulation periods and reduction of their weights, consequently of their prices as well, implicate improvements and applications of new composite materials with matrices of lightweight metals. Composite materials with metal conditions are used for engine connecting rod, cylinders, pistons, piston rings disc and drum brakes, shafts and for further rudiments in automotive and air travel industry. The most essential types of metallic materials is composite materials with a matrices of aluminium alloys due to a set of their positive properties. Enhancement of mechanical, mainly tribological properties of amalgam composites were delivered by the use of definite reinforce materials such as SiC, Al2O3 and graphite in demarcated weight or volumetric part. The modern developed hybrid composites are with a aluminium matrices to be having a mostly maximum resistance to wear, maximum specific stiffness and upper resistance to fatigue. By the increase of quantities of manufactured components made of hybrid composites, decrease of their prices is tempted that even promote enlarge their applications. The applications of aluminium hybrid composites are reflected from the aspect and with the emphasis on automotive industry

Design and Fabrication of Movable Headlight System in Automotive Vehicles

This paper presents the hardware of movable Headlight System for motorized vehicles. Headlight System is an active safety system, where the head lamp alignment control system rotates the right and left headlights independently and keeps the beam as parallel to the curved road as possible to provide better night time visibility to driver. In this system use rack and pinion arrangement which give drive to the optical axes on which headlight are attached so when a tie rod arms are moved with steering arm that give predefined motion to the wheel as well as headlights system
