ABSTRACT:
In making a hard multi-tubular structure, one starts with a flat woven or knitted hose fabric comprising a plurality of side-by-side hoses; the hoses of the fabric are caused to expand and to set in their expanded configurations, which may be circular or substantially square in cross-section by a hardenable medium with which the fabric is impregnated or coated. Optionally, a hardenable covering and/or filling is provided over or in the hoses.
