ABSTRACT:
Preliminary material for the production of composite material parts, consisting of a tubular outer part (1) and at least one core or inner part (2) and two sealing parts (3) positioned at the ends of the tubular outer part, as well as a process for the production of the preliminary material. The sealing parts (3) project at least partially into the outer part, and a surface pressure exists at the sealing surfaces (4). The materials of the outer part and the sealing parts have at least an equal thermal expansion coefficient and a fundamentally equal deformation resistance, and the material of the sealing parts have a higher distortion temperature. The process provides for thermal shrinkage of the sealing parts prior to insertion into the tubular part, and, when necessary, followed by evacuation of a residual cavity (6) between the inner and outer parts or filling of the residual cavity with inert gas.
