<p>Fiber-reinforced thermoplastic honeycomb (2) is prepared in a continuous manner one half cell at a time with the aid of formers (1, 4) by laying down a corrugated web of thermoplastic, selectively fusing the node-antinode demes, retracting the lowermost set of formers (1, 4), raising the formers by an amount at least equal to the thickness of the fused node-antinode surface, and repeating the process until a honeycomb of the desired depth is prepared. During at least a portion of the continuous manufacture, a thermoplastic web is utilized which has different characteristics from the webs utilized in the remaining portion of the process or the steps of laying down a corrugated web and fusing the demes are repeated without retracting and raising the lowermost set of formers so that a honeycomb material having areas or volumes possessing different physical properties than the remainder of the honeycomb is produced.</p> |
