摘要
The present invention relates to: a method in which an extruded aluminium alloy material is used to produce a T-shaped reinforcing material for reinforcing the strength of an LNG storage tank built into an LNG tanker; the reinforcing material; and an LNG storage tank module made by using same. Provided is a production method for a T-shaped reinforcing material for an LNG storage tank, wherein an aluminium alloy starting material is extruded in the form of a T-shaped reinforcing material by being passed through an extrusion mould, which has an extrusion-moulding part in the form of the T-shaped reinforcing material, while being heated to and isothermally maintained at a temperature of between 570 and 650°C, which is above the solidus line. Also provided are: a T-shaped reinforcing material which is produced by means of the production method; and an LNG storage tank module made by using same.
