摘要：The composite/metal hybrid structure, which has different impact damage characteristics compared with conventional composite structure, is widely used in composite Compressed Natural Gas (CNG) cylinders of new energy vehicles. This paper, combining both the tests of composite cylinder and specimen, evaluates cylinder's impact resistance performance with parameters such as: impact energy absorption rate, delamination extension resistance and attenuation factor of the residual strength ratio. It is found that, under certain impact energy, changing composite/metal hybrid structure leads to the change of impact energy absorption rate and increases impact damage critical value, namely, load bearing capacity. Higher impact energy absorption rate will reduce delamination extension resistance, and the residual strength of laminates with impact damage will attenuate faster. As a result, the effect of delamination extension resistance and impact energy absorption rate should be taken into consideration while designing composite cylinders. (c) 2012 Elsevier Ltd.
