Abstract
Official abstract text for this publication.
A low-temperature tank includes a container main body. The container main body includes a metal liner forming a storage space and a wall member formed of carbon fiber reinforced plastic wound on an outer peripheral surface of the metal liner. The metal liner includes a bent portion that extends in two directions intersecting each other on a surface thereof and that is bent to project toward the storage space.
First claim
Opening claim text (preview).
What is claimed is: 1. A low-temperature tank comprising a container main body that includes a metal liner forming a storage space of the low-temperature tank and a wall member formed of fiber reinforced plastic wound on an outer peripheral surface of the metal liner, wherein the metal liner includes a bent portion that extends in two directions intersecting each other on a surface thereof and that is bent to project toward the storage space. 2. The low-temperature tank according to claim 1 , further comprising a filler filled between the bent portion and the wall member. 3. The low-temperature tank according to claim 2 , wherein the filler is formed of an elastic body that maintains a shape when being filled at a sintering temperature of the wall member. 4. The low-temperature tank according to claim 2 , wherein the filler is formed of a material that maintains a shape when being filled at a normal temperature and that contracts at a sintering temperature of the wall member or lower. 5. The low-temperature tank according to claim 1 , wherein the metal liner has an uneven structure in a portion adhering to the wall member. 6. The low-temperature tank according to claim 2 , wherein the metal liner has an uneven structure in a portion adhering to the wall member. 7. The low-temperature tank according to claim 3 , wherein the metal liner has an uneven structure in a portion adhering to the wall member. 8. The low-temperature tank according to claim 4 , wherein the metal liner has an uneven structure in a portion adhering to the wall member. 9. A method for manufacturing a low-temperature tank, the method comprising: winding a metal liner around a mandrel, the metal liner including a bent portion that extends in two directions intersecting each other on a surface thereof and is bent to project toward the mandrel; winding a wall member formed of fiber reinforced plastic on an outer peripheral surface of the metal liner wound around the mandrel; sintering the wall member; and detaching the mandrel from the metal liner. 10. The method for manufacturing a low-temperature tank according to claim 9 , further comprising filling a filler into the bent portion. 11. The method for manufacturing a low-temperature tank according to claim 10 , wherein the filler is formed of an elastic body that maintains a shape when being filled at a sintering temperature of the wall member. 12. The method for manufacturing a low-temperature tank according to claim 10 , wherein the filler is formed of a material that maintains a shape when being filled at a normal temperature and that contracts at a sintering temperature of the wall member or lower.
