Solidification method of fiber-wound gas cylinder

Abstract

The invention discloses a solidification method of a fiber-wound gas cylinder. The method comprises the following steps of: (1) infusing a high-strength fiber material in a resin matrix, then winding the high-strength fiber material around the gas cylinder to form a fiber resin composite material layer on the surface of the gas cylinder; (2) horizontally arranging the well-wound gas cylinder in a first solidifying furnace, keeping the gas cylinder to constantly rotate around a center axis until the resin matrix in the fiber resin composite material layer gelatinates and finishes primary solidification; and (3) immediately transferring the gas cylinder subjected to the primary solidification in a second solidifying furnace and finishing the final solidification of the gas cylinder according to a general solidification measure. The solidification method has high solidification efficiency and is simple and easy to implement; and the solidified product has good appearance quality.

Description

technical field [0001] The invention relates to the field of manufacturing fiber-wound gas cylinders, in particular to a curing method for fiber-wound gas cylinders. Background technique [0002] With the widespread use of compressed gases such as natural gas, hydrogen, and helium, gas cylinders have become the preferred container for such compressed gases. In order to improve the volume-to-weight ratio and pressure-bearing capacity of gas cylinders, fiber-wound gas Bottle, the scheme is to wind the high-strength fiber-reinforced resin matrix on the outer wall of the metal seamless liner according to certain rules and solidify it to form a composite material layer. [0003] The curing of the composite material layer is one of the key processes in the manufacturing process of gas cylinders. Different curing methods will have a great impact on the performance and appearance quality of the product. At present, the rotary curing method is usually used. The appearance quality of...

Problems solved by technology

At present, the rotary curing method is usually used. The appearance quality of this method is good, but the curing efficiency is extremely low. This is because the curing time of the gas cylinder is usually more than 5 hours, while the general rotary curing furnace can only cure 1-2 times each time. cylinder only

In this way, a large number of curing furnaces need to be configured during the mass production of gas cylinders, which requires a large investment in equipment and large energy consumption.

Another curing method is to use a hanging curing furnace or a hanging walking curing furnace, which can cure dozens to hundreds of gas cylinders at a time, but because the gas cylinders are vertical to the ground during curing, the upper part of the gas cylinders will The glue and fibers flow downward, causing the lower part of the cured gas cylinder to show glue flow and fiber slippage, which affects the performance and appearance quality of the product
