A METHOD OF MAKING A TUBULAR CASING FOR AN UNDERWATER DEVICE, IN PARTICULAR A TORPEDO

摘要

A method of making a tubular casing for an underwater device, wherein a metal ring (2) made of aluminium is subjected to an anodizing process that produces an insulating layer (12) of aluminium oxide that covers it externally. The ring is coupled with a mould (15) that defines a cylindrical surface (16) on which the following are deposited: first layers of carbon fibre (20a) to produce a first cylindrically-shaped tubular element in carbon fibre provided with an end portion that engages a first groove (7) of the ring; a layer of syntactic material (22) configured to transfer radial forces; and second layers of carbon fibre (20b) to produce a second cylindrically-shaped tubular element in carbon fibre that covers the syntactic layer and is provided with an end portion that engages a first groove (7) of the ring.
