<p>A laminate bulkhead comprises an expandable polymer (24) sandwiched between two stiff members (10) and (12) which are of a structure so that the expandable polymer (24) is flared out or thicker in the area or along the line where the polymer (24) expands and is bonded to the walls of a hollow structure in which the bulkhead is placed. The direction of expansion of the polymer (24) results from the polymer being constrained by the stiff members on either side of the expanding (24).</p> |
