Description

Technical Field

[0001] The patent of this invention relates to a method for fiber winding of hydrogen storage cylinders, and specifically to a method for fiber winding of a 210L-Ⅳ type 70MPa hydrogen storage cylinder. Background Art

[0002] The development of composite high-pressure hydrogen storage cylinders began in the 1950s. The cylinders are characterized by light weight, high strength, high modulus and strong designability, and are widely used in important fields such as aerospace, automobiles, and rockets. The winding process of carbon fiber hydrogen storage cylinders usually includes two types of lines, one is circumferential winding and the other is spiral winding. The above two winding lines provide circumferential and axial strength for the cylinders respectively. According to the different length and shape characteristics of the liner, a specific winding method needs to be set. The circumferential winding method mainly involves the yarn width and winding angle; the spiral winding method mainly involves the yarn width, hole expansion size, number of tangent points, and winding angle. At present, by changing the number of tangent points, the laying scheme, and the tension size, the problems of slip line and profile during large hole expansion winding in the winding molding process of 140L-Ⅳ type 70MPa hydrogen storage cylinders have been solved, and the development of 140L-Ⅳ type 70MPa hydrogen storage cylinders has been successfully realized.
