Research on Inspection Method for Aluminum-Lined Carbon Fiber Fully Wrapped Composite Cylinders for Compressed Hydrogen in Vehicles
With the issurance of policies for developing the hydrogen energy industry by national and local governments,hydrogen-powered vehicles in China are gradually becoming popular. The safety and reliability of research on inspection method of aluminum liner carbon fiber fully wrapped fibre reinforced composite gas sylinders of compressed hydrogen gas for automotive vehicles have increasingly become a focus of attention due to the continuous development of hydrogen storage technology. According to relevant regulations,this type of hydrogen storage equipment is classified as special equipment subject to mandatory inspection. In recent years,hydrogen cylinders have also reached their peak inspection period. In order to address the inspection challenges,this paper has developed and installed a set of inspection and testing lines for hydrogen cylinders based on the preparation of inspection sites,design of inspection process flow,arrangement of inspection stations,and attention points during inspections. Through testing and multiple adjustments on the inspected cylinders as well as the inspection line itself,the results indicate both the inspection method and testing line fully meet national regulatory requirements. After passing trial inspections successfully,optimization suggestions are proposed based on current methods and requirements in order to improve effectiveness in inspecting hydrogen cylinders while providing reference for upgrading future inspection lines. This provides strong technical support for widespread application of hydrogen-powered vehicles.
