Description

Technical field [0001] The present application belongs to the technical field of composite resin material, and more particularly to a composite resin material for pressure gas storage containers and a preparation method thereof. Background technique [0002] The hydrogen storage system is one of the core components of the fuel cell system, which includes high-pressure hydrogen storage bottles, safety valves, and pipelines. Among them, high-pressure storage bottles are mainly responsible for storing high pressure gant hydrogen, its working conditions, and health status determine the safety of the entire fuel cell car and service life. Plastic liner, carbon fiber all-wound four high-pressure storage bottles, due to light weight, high gas storage density, and more likely to be more likely to be more likely to be more likely to exceed metal systems, and are widely expected by the market. Currently, the four high-pressure hydrogen storage bottles are mainly applied to a more sensitive...
