Apparatus for making nested honeycomb structures

摘要

A nested fiberglass structure (10) comprises a plurality of strips (66) each in the shape of a sinusoidal wave (20). The waves (20) have peaks (22) and valleys (24) which have equal amplitudes about a central axis (26). A positioning string (32) is placed over the peaks (22) and into the valleys (24) to provide a guide for the depth of penetration of adjacent strips during nesting of the strips (66). The structure (10) may be formed on an apparatus for manufacturing (46) which forms a continuous web (48) into the strips (66) and nests the strips (66) into the structure (10). The structure (10) may then be wound onto a reel (154) for fabrication into a cylindrical structure (34). The apparatus (136) spirally winds the nested structure (10) around a mandrel (182) to form the cylindrical structure (34).
