Weight reduction of vehicle sub-assemblies using thin-walled adhesively bonded steel composite structures
In recent years, work has been carried out to seek effective means of reducing the weight of vehicle structures, primarily through the use of certain high-strength steels. This research has involved the use of steel sheet with increased strength to compensate for a reduction in sheet thickness: for example, body panels of thickness down to 0.6/0.7 mm and structural members down to 1.2 mm. The possibility of enhanced weight reduction by reducing the thickness much more significantly than in earlier research was explored by using body panels of thickness down to 0.3 mm and compensating for this thickness reduction by inducing geometric changes in the plane of the sheet to enhance the structural moduli of sub-assemblies. These changes included the use of rigidised/embossed sheet, produced by rolling techniques, together with specially designed composite panels made from rigidised/embossed sheet adhesively bonded to equally thin flat 'skins'.
