After full composite high pressure gas bomb has wound carbon fiber strength layer group 4 and glass fibre protective layer group 5, in next step
It is to be cured, the compound gas bomb of high pressure is put into curing oven, and is cured in warm area, when full composite high pressure gas bomb
It is taken out out of curing oven after being cooled to certain temperature after the completion of solidification in warm area again, the cooling temperature is less than the first temperature in curing oven
The temperature in area and the second warm area can guarantee that the composite layer after solidification gradually cools down, Direct Air-Cooled avoided to increase resin in this way
Brittleness；Bottleneck and bottle tail are horizontally-supported in the curing process, so that full composite high pressure gas bomb is rotated horizontally in curing oven, in this way
It can obtain protecting liner indeformable while preferable the surface of gas cylinder quality can be obtained again.Wherein, the temperature of warm area is 90 DEG C, always
Hardening time between 4.5 hours to 10 hours,
In the curing process, aathermoset resin system crosslinks full composite high pressure gas bomb, assigns carbon fiber strength layer
4 a degree of anti-shearing, anticorrosive, chemical stabilities of group and transmission fibre stress etc..Make glass fibre protective layer group 5 simultaneously
Molding, it is injury-free with the carbon fiber strength layer group 4 inside ensureing full composite high pressure gas bomb when being impacted and being corroded, it keeps away
The performance for exempting from full composite high pressure gas bomb is destroyed, to extend the service life of full composite high pressure gas bomb.
After full composite high pressure gas bomb cures, the water pressure test and inner wall drying and processing are carried out to it, pass the test is simultaneously
And it can come into operation after being disposed.
Above-described embodiment is only one of preferred embodiments of the present invention, should not be taken to limit the utility model
Protection domain, as long as the utility model body design thought and that mentally makes have no the change of essential meaning or profit
Color, it is solved the technical issues of it is still consistent with the utility model, the scope of protection of the utility model should all be included in
Within.
