Notes:
As one type of the important alternative fuel containers, composite cylinders are widelyused in compressed natural gas vehicles (CNGV) all over the world. Compared to traditional metalcontainers, the performance of composite cylinders is more complicate because it is difficult toanalyze the material characteristics and the influence of manufacturing process. With the aid ofnumerical simulation, the damage tolerance of one type of composite cylinder was investigated inthis paper. Firstly, the usual damage modes and sizes that are generated in the serviced compositecylinders are classified to illustrate the dangerous parts in the composite cylinders. According to themanufacturing process of composite cylinders, the fiber material characteristics that account of theeffects of heat and resin are evaluated to conduct the numerical simulation. Under the damagemodes and sizes such as initial flaw, fiber fracture and delamination that are distributed in thecylinder in terms of the classification, the performance of composite cylinder are carried out. Withthe convenience of numerical simulation, the map of the dangerous sites under the elaboratedamage modes and sizes is given to evaluate the running condition of composite cylinders inpractice. The quantitative results are more useful to show the damage tolerance of compositecylinder than the traditionally qualitative check way and guarantee the running of CNGV
