Abstract:For carbon fiber composite vessel with thin鄄wall metal liner, the basis of netting theory and the expe鄄
rience value method of developed fiber strength easily induce that practice burst pressure is far higher than design
pressure, and developed percentage of fiber strength is higher than design value. The reason is mainly analyzed in the
paper,solving approaches and some methods in design are presented. Firstly,composite technique is designed mainly
based on practical fiber strength;Secondly,load鄄bearing of liner and resin should be calculated;Thirdly,fibers of vari鄄
ous tensile strength are classified;Fourthly,iso鄄strength enveloped design method and reinforced dome technology can
be adopted to improve the situation. The above measures are used in order to develop fiber strength of composite vessel
sufficiently, to reduce cost and to increase structural efficiency.
