The invention relates to a method for producing a carbon
fiber-completely winded composite
gas cylinder with an aluminum inner container. The carbon
fiber-completely winded composite
gas cylinder with the aluminum inner container has
main bearing structures of the aluminum inner container and a carbon
fiber completely-winding layer. The carbon fiber completely-winding layer on a cylinder body is prepared by alternately winding longitudinally spirally winding fiber
layers and circumferentially winding fiber
layers in a laying order designed optimally.
Glass fiber layers are winded on the surface of the carbon fiber completely-winding layer and are used as
impact resistant protective layers of the carbon fiber-completely winded composite
gas cylinder with the aluminum inner container. The carbon fiber-completely winded composite gas cylinder with the aluminum inner container has main technical indexes of a safety factor great than or equal to 3.4 and fatigue cycle number N great than or equal to 10000. The method provided by the invention satisfies reasonable
stress field distribution, and guarantees that the carbon fiber-completely winded composite gas cylinder with the aluminum inner container can bear maximum
burst pressure under the condition of a minimum fiber use amount, produces cracks located at a cylinder body and does not produce fragments. The method guarantees that the aluminum inner container of the carbon fiber-completely winded composite gas cylinder with the aluminum inner container is always in an elastic deformation state under preset
work pressure, and guarantees that the carbon fiber-completely winded composite gas cylinder with the aluminum inner container has lasting and good gas tightness and optimal safety.
