Ultraviolet curing composite material pressure container and forming method

Abstract

The invention relates to an ultraviolet curing composite material pressure container and a forming method, and mainly solves the problems of low curing speed, low efficiency, uncontrollable quality, high energy consumption and the like in the traditional curing of a composite material pressure container. The ultraviolet curing composite material pressure container comprises a protective layer, a composite material winding layer and an inner container. The forming method comprises the steps that prepreg is wound on the surface of the inner container through a winding machine according to a track planned in advance, ultraviolet light is irradiated outside so as to complete winding and curing in one step, and the inside of the inner container needs to be inflated and pressurized during winding. According to the ultraviolet light curing forming method, a curing oven with a large size is not needed, the energy is clean, the manufacturing cost is low, the manufacturing process is simple and environmentally friendly, and the resin viscosity is controllable.

Description

technical field [0001] The invention belongs to the field of composite material containers, in particular to an ultraviolet light curing composite material pressure container and a molding method. Background technique [0002] Fiber-reinforced composite materials are widely used in various civil buildings and bridges because of their high specific strength, large specific modulus, designable material properties, good corrosion resistance and durability, and similar thermal expansion coefficient to concrete. , highways, oceans, hydraulic structures and underground structures and other fields. [0003] For traditional wet winding composite material containers, such as gas cylinders, the gas cylinder needs to be disassembled from the work station during curing, and the whole is put into a curing furnace for heating and curing, and finally the finished product is obtained. It has the following problems: 1. The inner liner of the gas cylinder is a metal inner liner, and the mold...

AI Technical Summary

Problems solved by technology

It has the following problems: 1. The inner liner of the gas cylinder is a metal inner liner, and the molded product is very heavy; 2. The process of winding first and then curing is too complicated to achieve in-situ curing, which wastes time and reduces production efficiency; 3. After the bottle is wound, it is placed in the curing furnace and does not move, resulting in uneven heating; 4. The glue liquid flows downward due to gravity, resulting in uneven glue content per unit; 5. The curing furnace occupies a large area, causing Waste of space; 6. The curing time is long and the curing effect cannot be intuitively felt

[0004] CN201820765752.0 discloses a winding gas cylinder curing device, but its curing device is only suitable for curing the outer layer of the winding gas cylinder. If the wall thickness of the gas cylinder is thicker, the side close to the inner tank may not be completely cured, so it is urgently needed A new solidified way to solve such problems
