Abstract

The mandrel, for fabricating a large hollow body by applying successive layers of synthetic resin and winding fibres, consists of contoured plates and reinforcing elements including a rotary shaft drive and supports for the plates, the shaft having two coaxial portions connected by articulating elements to reinforcements supporting the plates so that the structure can be folded while remaining rigid. The plates may be of synthetic resin impregnated glass fibres which are polymerised. The structure is preferably a cylinder with convex ends. The mandrel is useful for fabricating tanks and similar bodies.
