ABSTRACT:
The present door, such as a motor vehicle door, has a central member extending from the hinges to the lock. The central member carries an interior and an exterior door panel. The central member is a body of compound synthetic hard foam material having embedded therein an energy absorbing element. Additionally, the central member is encased in two shells. This structure is lightweight and yet stiff against shearing and torsion loads as well as impact forces.
