Winding forming method of composite material gas cylinder with inner grid ribs

Abstract

The invention discloses a winding forming method of a composite material gas cylinder with inner grid ribs, and belongs to the technical field of gas cylinder structures. Composite material gas cylinder with inner grid ribs, including the outer layer of the gas cylinder and the inner layer of the grid; the outer layer of the gas cylinder and the inner layer of the grid are made of composite materials; the inner layer of the grid is in the shape of a bottle liner, and the grid The inner layer is a grid rib structure; the outer layer of the cylinder is wound and connected to the outside of the inner layer of the grid. It solves the technical problem that in the prior art, the gas cylinder adopts a plastic liner, resulting in a relatively thin overall structure and weak axial compression resistance; the gas cylinder adopts a metal liner, resulting in heavy overall weight and unable to meet the use requirements. In the present invention, a grid inner layer is arranged inside the outer layer of the gas cylinder, and the grid inner layer is a dense inner grid rib structure, which improves the axial compression resistance of the entire gas cylinder, and is made of composite materials to realize the gas cylinder lightweight.

Description

technical field [0001] The invention relates to the technical field of gas cylinder structures, in particular to a composite material gas cylinder with inner grid ribs and a winding forming method thereof. Background technique [0002] Due to the light weight and high pressure resistance of composite gas cylinders, composite gas cylinders have a wide application base in aerospace and civil fields. In the prior art, the structure of the gas cylinder made of composite material is a structure of an inner liner and an outer layer of composite material, so as to improve the overall compression resistance of the gas cylinder. [0003] The liner of the composite gas cylinder is usually made of metal liner or plastic liner to ensure that the overall internal pressure of the composite gas cylinder can reach 100MPa to meet the needs of use. [0004] However, when the gas cylinder in the prior art uses a plastic liner, since both the plastic liner and the outer layer of the composite ...
