ABSTRACT:
A bumper core suitable for use in the fabrication of an energy-absorbing automobile bumper is formed by molding core-constituting members in accordance with the expansion molding process and then bonding them together at their confronting lengthwise end portions into a unitary body. The core-constituting members are formed into such configurations and dimensions that conform with configurations and dimensions obtained by longitudinally dividing the intended core into at least two parts. The bumper core enjoys extremely-high dimensional accuracy.
