a) A stacking table ( 11 ) having a movable upper surface ( 13 ) with the shape of the piece to be manufactured;

b) A movable head ( 15 ) on said stacking table ( 11 ) provided with the following means:

b 1 ) Automatic means for placing tapes ( 19 ) or rovings of composite material in the form of prepreg;

b 2 ) Compacting means for compacting the composite material;

b 3 ) Microwave emission means ( 25 ) for curing the composite material.

2 . A tool ( 9 ) for manufacturing pieces of composite material outside an autoclave according to claim 1 , characterized in that it is structured such that the movements of the head ( 15 ) and the upper surface ( 13 ) of the stacking table ( 11 ) allow the stacking of the desired piece.

3 . A tool ( 9 ) for manufacturing pieces of composite material outside an autoclave according to claim 2 , characterized in that it is structured such that the upper surface ( 13 ) can rotate about an axis located in the center thereof and move along the stacking table ( 11 ). and the head can move along the entire width of the stacking table ( 11 ).

4 . A tool ( 9 ) for manufacturing pieces of composite material outside an autoclave according to claim 1 , characterized in that said compacting means include a roller ( 39 ) and an ultrasonic unit ( 41 ).

5 . A tool ( 9 ) for manufacturing pieces of composite material outside an autoclave according to claim 1 , characterized in that the head is structured such that it can be configured with any operational state of the mentioned means.

6 . A tool ( 9 ) for manufacturing pieces of composite material outside an autoclave according to claim 1 , characterized in that the head is structured such that the order of action of the mentioned means can be modified.
