Abstract
A provisional linking and pyrotechnic separation device is placed between two assemblies made from nonmetallic materials such as composite materials. Prior to separation, parts belonging to each of the two assemblies are fixed to one another, either by direct bonding of the parts to one another, or by bonding a linking part to the parts. The device includes a pyrotechnic expansion tube acting directly on one of the parts to be separated. A precise, clean and well localized separation of the assemblies consequently takes place during the use or operation of the pyrotechnic expansion tube.
