Abstract:
1. Equipment to manufacture composite material parts comprising at least one composite material element to be compacted, the equipment comprising: a frame having a plurality of arms, interconnected along a determined perimeter, and comprising an upper side and a lower side; at least one vacuum bag attached to the lower side of said frame along the determined perimeter of the frame and configured to compact said at least one composite material element; and a member attached to the vacuum bag along said determined perimeter of the frame and configured to become in contact in a removable way with a surface, on which the at least one composite material element to be compacted is positioned, to define a compacting zone of said at least one composite material element, wherein the arms are configured to create a common internal channel or channels connectable through a connection element to a pump, and comprise a plurality of holes positioned proximate the lower side of the frame, the member is comprised of a foam material having semi-closed cells, which are porous in an uncompressed form and not porous in a compressed form, the plurality of holes communicates with the foam material through the vacuum bag while an air influx is generated by the pump through the foam material attached along the determined perimeter of the frame, and the foam material blocks the air influx when the foam material becomes compressed.
