Abstract
A cellular structure is formed on a wheel from an elongated tubular structure. At least one longitudinal line of a slow cure adhesive is applied to the exterior surface of the elongated tubular material. Then the material is wrapped around a collector in a manner to cause the adhesive to be positioned between overlying surfaces of the elongated tubular material and to form a cellular structure on the collector. The cellular structure is cut from the collector before the adhesive has fully cured and is placed on a flat surface where the adhesive has fully cured.
Claims8
A method of making a honeycomb structure comprising:
- providing an elongated tubular material having an exterior surface,
- applying at least one longitudinal line of an adhesive to the exterior surface of the elongated tubular material, the adhesive being a slow cure adhesive that will not fully cure for at least one hour,
- wrapping the elongated tubular material around a collector on a surface having at least one curved portion in a manner to cause the adhesive to be positioned between and bond to overlying surfaces of the elongated tubular material and to form a cellular structure on the collector, the cellular structure having a curvature,
- making at least one transverse cut through the cellular structure, the cut being made before the adhesive has fully cured,
- placing the cellular structure on a flat surface before the adhesive has fully cured, and
- allowing the adhesive to fully cure while the cellular structure is on the flat surface such that the curvature in the cellular structure will flatten while the adhesive fully cures.
