1. method that forms honeycomb composite structure, described honeycomb composite structure comprises first top layer, second top layer and place between first and second top layers and with the described honeycomb core that both link to each other, wherein first and second top layers all comprise at least one fibre plate and polymeric matrix, and all be curing or uncured, described method comprises:

  • the gross porosity fabric is placed between in the honeycomb core and first and second top layers at least one, in the process in conjunction with at least one and honeycomb core in first and second top layers fluid can be flowed between the abscess at honeycomb core;

    In first and second top layers at least one worn at least one steam vent, and the size of described steam vent before being aggregated the sealing of thing matrix, can flow fluid in the process in conjunction with at least one and honeycomb core in first and second top layers;

    And in conjunction with at least one and honeycomb core in first and second top layers.
