Abstract
The utility model relates to an enhanced fibrous plastic cylinder with an internal spiral reinforced rib, particularly an enhanced fibrous plastic cylinder. The utility model solves the problems that the existing metal material cylinder has heavy weight, has need of a special lifting device and has high cost. Besides, the inner surface of the existing metal material cylinder has slight cracks. The utility model is formed by superposing a cylinder inner lining (1) of resin matrix composite materials, a cylinder outer layer (2) of resin matrix composite materials, and an internal spiral reinforced rib (3) of resin matrix composite materials, wherein the cylinder inner lining (1) is provided with at least one internal spiral reinforced rib (3) and a groove; the internal spiral reinforced rib (3) is arranged in the groove; the length of the internal spiral reinforced rib (3) is at least 1/3 of the length of the cylinder; the cylinder outer layer (2) is fixed to the outer surface of the cylinder inner lining (1) and the internal spiral reinforced rib (3). The utility model is suitable for making cannon barrels, gun barrels, etc. The density of the enhanced fibrous plastic cylinder is 1/4 of that of metal material steel. Thus, the weight of the enhanced fibrous plastic cylinder which is convenient to turn over is largely reduced. Besides, the inner surface of the enhanced fibrous plastic cylinder is smooth and the utility model has the characteristics of high temperature resistance, corrosion resistance, leakage resistance and low cost.
Description
Technical field
The utility model relates to the fibre reinforced plastics tube.
Background technology
At present, the cylindrical shell of existing similar structures is that metal material adopts Broaching Technology, Electrolyzed Processing or the moulding of cold metal processing method.Cylindrical shell with the said method moulding need use the inner surface of special processing equipment, shaping rear cylinder body that micro-crack is arranged, and cylindrical shell is heavy, and the cost height needs to use special-purpose hanging device to process and have enough to meet the need in the processing.
The utility model content
The utility model is heavy in order to solve existing metal material cylindrical shell, need special-purpose hanging device in the processing, and the inner surface of moulding rear cylinder body has micro-crack and the high problem of cost, and a kind of fibre reinforced plastics tube with the inside spin reinforcement is provided, and the concrete technical scheme that addresses the above problem is as follows:
The utility model is made by polymer matrix composites cylindrical shell inner liner 1, polymer matrix composites cylindrical shell outer 2 and 3 stacks of polymer matrix composites inside spin reinforcement, polymer matrix composites cylindrical shell inner liner 1 is provided with at least one helical groove, polymer matrix composites inside spin reinforcement 3 is fixed in the helical groove, polymer matrix composites inside spin reinforcement 3 is at least 1/3rd of cylindrical shell length, and polymer matrix composites cylindrical shell skin 2 is fixed on the outer surface of polymer matrix composites cylindrical shell inner liner 1 and polymer matrix composites inside spin reinforcement 3.
The utility model is applicable to makes gun barrel, gun barrel etc., this adopts polymer matrix composites density is 1/4 of metal cylinder material (steel), make the weight of cylindrical shell obtain significantly reducing, turnover is convenient, the performance test index of cylindrical shell: press 0.1～10MPa in can bearing; Bending rigidity reaches 8.3 * 10
4Nm
2Torsional rigidity reaches 3.5 * 10
