Claims (4)

1. Несущая труба-оболочка из композиционных материалов, содержащая силовой каркас ячеистой структуры из повторяющихся по толщине его стенки слоев систем перекрещивающихся спиральных и кольцевых лент, образующих узлы перекрестий и ребра жесткости между ними, и внешнюю силовую оболочку, соответственно выполненные из однонаправленных нитей, скрепленных полимерным связующим, отличающаяся тем, что ее силовой каркас снабжен конгруэнтными охватывающими его ребра жесткости по их направлениям мелкоячеистыми слоями систем перекрещивающихся спиральных и кольцевых лент из однонаправленных нитей, или тканых лент, или их комбинации, имеющих ширину, превышающую ширину лент в ребрах, и образующих их опорные полки, скрепленные с ними и внешней силовой оболочкой полимерным связующим.1. The supporting pipe-shell made of composite materials, containing the power frame of the cellular structure from the layers of systems of intersecting spiral and circular ribbons repeating over the thickness of its wall, which form the nodes of the crosshairs and stiffeners between them, and the external power shell, respectively, made of unidirectional threads, fastened together polymer binder, characterized in that its power frame is equipped with congruent stiffening ribs covering it in their directions with fine-mesh layers of intersecting systems piralnyh and annular strips of unidirectional filaments, tapes or woven, or combinations thereof, having a width exceeding the width of strips in the ribs, and forming their bearing flange, fastened with them an external structural envelope and a polymeric binder. 2. Труба-оболочка по п.1, отличающаяся тем, что углы между спиральными ребрами, противолежащие кольцевым ребрам, равны 50 - 60o.2. The shell pipe according to claim 1, characterized in that the angles between the spiral ribs, opposite the annular ribs, are 50-60 o . 3. Труба-оболочка по пп.1 и 2, отличающаяся тем, что спиральные ребра между узлами их пересечения пересечены кольцевыми ребрами с равным шагом по их длине. 3. The shell pipe according to claims 1 and 2, characterized in that the spiral ribs between the nodes of their intersection are crossed by ring ribs with an equal pitch along their length. 4. Труба-оболочка по пп.1 и 2, отличающаяся тем, что узлы пересечения спиральных ребер выполнены с двусторонними примыканием к их перекрестиям кольцевых ребер. 4. The shell pipe according to claims 1 and 2, characterized in that the nodes of the intersection of the spiral ribs are made with bilateral adjacent to their crosshairs annular ribs.
