Compaction process of a piece of composite materials

COMPACTION PROCESS OF A PIECE OF COMPOSITE MATERIALS, comprising:

• applying a mould release agent on a coating piece manufacturing tool (1) and carrying out its curing;
• applying a layer with adhesive properties (2) on the mould release agent, in order to leave a smooth surface of the piece to be obtained,
• characterized in that further comprises:
• extending along the layer with adhesive properties (2) an aerator blanket (4) with dimensions larger than said layer with adhesive properties (2);
• extending a membrane with resilient properties (5) on the entire surface of the tool (1), avoiding leaving folds and that the blanket (4) does not protrude;
• and the membrane with resilient properties (5) including a vacuum valve (6) in order to extract the air comprised between the membrane with resilient properties (5) and the tool (1), and compacting the layer with adhesive properties (2) keeping the vacuum for certain time;
• removing the membrane with resilient properties (5) and the aerator blanket (4).
