Abstract
A motor vehicle structural energy absorbing member (12) is light weight and is made in a manner to produce random or directionally oriented, elongated pores or voids (16) in a structural matrix (14) in a manner that permits tailoring of impact energy absorption in one or more direction(s) to provide an integral energy absorbing region.
