Formability of sheet materials for light automotive panels

Abstract

Reduction of fuel consumption and decrease of exhaust gases emission are among the most important working tasks for car producers from all over the world. Integration of the latest achievements in the area of science and technics has led to the realization of special results in this area, regarding motor construction and light car body making. With that purpose, in the last few years materials for manufacture of car bodies of reduced weight, such as high strength steel sheet metals, Al-sheet metals, titan and its alloys, sandwich and composite materials, tailored welded blanks, were used more and more. The paper gives survey of these materials, the application area, main advantages and disadvantages, description of formability parameters and results of researches in the area of boundary formability of these materials.
