US 12,429,166 B2 · Cryogenic storage tank, aircraft with a cryogenic storage tank and method for forming a hybrid metal polymer joint

Abstract

A cryogenic storage tank including a first metallic end piece having a first structured connection area on its outer surface, a second metallic end piece having a second structured connection area on its outer surface, a hollow body extending between the first structured connection area and the second structured area. The hollow body is formed of a fiber reinforced polymer-based composite, a first metallic clamp having a third structured connection area and a second metallic clamp having a fourth structured connection area. The hollow body is arranged between and in intimate contact with the first structured connection area of the first metallic end piece and with the third structured connection area of the first metallic clamp and is arranged between and in intimate contact with the second structured connection area of the second metallic end piece and with the fourth structured connection area of the second metallic clamp.

Dependent claims

A method for forming a hybrid metal-polymer joint, the method comprising:

forming a first structured surface on a first connection area of a first metallic object;
forming a second structured surface on a second connection area of a second metallic object;
applying one or more composite plies, which are fiber-reinforced and polymer based, to the first structured surface;
welding the one or more composite plies to the first structured surface of the first connection area;
applying the second structured surface of the second connection area of the second metallic object onto the one or more composite plies that are welded to the first structured surface of the first connection area of the first metallic object;
and
welding the second structured surface of the second connection area of the second metallic object to the one or more composite plies, and
wherein the first metallic object is a first metallic end piece of a cryogenic storage tank and the first connection area is a first annular flange arranged in an outer surface of the first metallic end piece.
