Abstract
The present invention relates to an automated method for manufacturing layer by layer a composite part with rotational symmetry and complex cross-section, comprising the following stages: a) a reel or roll comprising a reinforcement is continuously unwound; b) as an option, the reinforcement is impregnated with a liquid resin by passing through a bath; c) the impregnated reinforcement is wound onto a rotating cylindrical mandrel; d) the impregnated reinforcement is completely or partially polymerised in order to obtain a composite material; e) a support and/or support material is deposited on both sides of the composite material forming the part being manufactured in such a way as to fill the gaps surrounding said part.

Automated method for manufacturing layer by layer a composite part with rotational symmetry and complex cross-section, the method for manufacturing each layer comprising the steps of:
- a) continuously unwinding a reinforcement (1,11) from one of a reel or roll, said reinforcement being one of dry or pre-impregnated;
- b) impregnating the reinforcement with a liquid resin by passing the reinforcement through a bath (2) when the reinforcement of step a) is dry;
- c) continuously winding the impregnated or pre-impregnated reinforcement (22) onto a rotating cylindrical mandrel (4);
- d) at least partially polymerizing the impregnated or pre-impregnated reinforcement (22) in order to obtain a layer of composite material (20);
- e) continuously depositing a removable support (21,9) on both sides of the layer of composite material (20) being disposed onto the rotating cylindrical mandrel (4) to fill gaps surrounding the composite part.
