Dry yarn winding forming method for pressure container

Abstract

The invention discloses a dry yarn winding forming method for a pressure container. The method comprises the following steps: 1. carrying out outer surface treatment on an inner container of the pressure container, namely coating an adhesive uniformly on the outer surface of the inner container of the cleaned pressure container; 2. carrying out dry yarn winding forming, namely winding on the outer surface of the inner container of the pressure container in a winding mode of alternative longitudinal winding and hoop winding, and carrying out continuous transition between the longitudinal winding and hoop winding under the condition that fibers are not cut off; 3. carrying out loose-proof strapping treatment on the port of a dry yarn winding forming body; 4. carrying out spraying forming treatment on a protective layer at the surface layer of the dry yarn winding forming body; and 5. placing and solidifying at room temperature. The dry yarn winding forming method for the pressure container provided by the invention has the advantages of reasonable design, simplicity and convenience in operation, convenience in control and good winding forming effect; and because an impregnation process and a solidifying process link are omitted, a plurality of practical problems, such as complex forming technology, longer production cycle, higher cost, no large scale of industrial production andthe like, of the existing winding forming process can be solved effectively.

Description

technical field [0001] The invention belongs to the technical field of composite material forming technology, and in particular relates to a dry yarn winding forming method for pressure vessels. Background technique [0002] Composite material pressure vessels have the advantages of light weight, high strength, and low manufacturing cost. At the same time, they have the fatigue failure mode of leakage before blasting that metal vessels do not have, and have significant advantages in terms of safety. In the traditional composite material container, the fiber-impregnated resin is wound on the surface of the inner tank material to prepare the composite material layer. The resin acts as a matrix material to solidify the fiber into a whole and transmit the load. The fiber acts as a reinforcement to bear most of the pressure load. , the combined effect of fiber and resin properties makes the composite material have excellent properties. Composite containers prepared by traditiona...
