Composite production system

A composite production system (1) comprising:

• a mold (2);
• a plurality of fabrics (3) laid on the mold (2);
• at least one vacuum bag (4) which is placed on the mold (2) so as to substantially cover the plurality of fabrics (3) and to allow vacuuming;
• at least one bleeder (E) located between the mold (2) and/or the plurality of fabrics (3);
• at least one separator layer (5) which is located between the vacuum bag (4) and the plurality of fabric (3) and enables the excess resin in the plurality of fabrics (3) to be substantially absorbed by the bleeder (E), thus providing homogeneous pressure distribution;
• at least one main vacuum line (6) located on the vacuum bag (4), which allows evacuation of the air and/or the resin in the plurality of fabric (3) and/or the air between the vacuum bag (4) and the mold (2);
• a first vacuum pump (7) which is connected to the main vacuum line (6) and generates a pressure required to evacuate the air;
• at least one discharge line (8) located on the vacuum bag (4), with at least one end thereof connected to the main vacuum line (6);
• at least one auxiliary vacuum line (9) with at least one end thereof connected to the at least one discharge line (8), wherein the at least one auxiliary vacuum line (9) creates a lower pressure than the main vacuum line (6) to substantially evacuate the air contained in the vacuum bag (4), thereby enabling the pre-vacuuming process to be performed;
• a second vacuum pump (10) connected to the at least one auxiliary vacuum line (9) and providing the necessary pressure to evacuate the air;
• and
• at least one valve system (11) located on the at least one discharge line (8), which allows only one of the main vacuum line (6) or the at least one auxiliary vacuum line (9) to be fed by the at least one discharge line (8) in order to keep a pressure value of the main vacuum line (6) and/or the at least one auxiliary vacuum line (9) at a pressure value determined by a user.
