Abstract
Official abstract text for this publication.
A method of manufacturing a tank comprises providing a covered liner by winding a fiber impregnated with a thermosetting resin on a liner; and performing a heat curing process that cures the thermosetting resin by heating the covered liner in a heating furnace. The heat curing process comprises controlling the heating to prevent temperature of the thermosetting resin that is changed by the heating from exceeding a heat resistant temperature of the liner.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a tank, comprising: (a) providing a covered liner by winding a fiber impregnated with a thermosetting resin on a resin liner; and (b) performing a heat curing process that cures the thermosetting resin by heating the covered liner in a heating furnace, wherein the (b) comprises controlling the heating to prevent temperature of the thermosetting resin that is changed by the heating from exceeding a heat resistant temperature of the liner, and wherein a second furnace ambient temperature increase rate after a furnace ambient temperature reaches a predetermined temperature, is higher than a first furnace ambient temperature increase rate after a start of the heating and before the furnace ambient temperature reaches the predetermined temperature, the predetermined temperature being a temperature at which rapid self-heating of the thermosetting resin is started. 2. The method of manufacturing the tank according to claim 1 , wherein the (b) further comprises stopping the heating at a peak of self-heating of the thermosetting resin. 3. The method of manufacturing the tank according to claim 2 , wherein the (b) further comprises restarting the heating on termination of self-heating of the thermosetting resin. 4. The method of manufacturing the tank according to claim 1 , wherein the (b) comprises controlling the heating, based on a profile that is configured to relate furnace ambient temperature in the heating furnace to time. 5. The method of manufacturing the tank according to claim 1 , wherein the (b) comprises controlling the heating, based on an actually measured furnace ambient temperature in the heating furnace. 6. The method of manufacturing the tank according to claim 1 , wherein the (b) comprises controlling the heating, based on an actually measured temperature of the thermosetting resin.
