Airborne radome wall for radio detection and ranging of e.g. aircraft, has films made of resin and introduced in pores, where resin flows towards pores to fill pores during pressure of tissue layer on core and upper skin on tissue layer

摘要

The wall (1) has a central core (5) arranged between internal lower and external upper skins (2, 7). An alveolar tissue layer (3) and a foam layer (6) are arranged on both sides of the core. One of the layers is provided with meshes (11) and open pores (14) in which adhesive films (10, 13, 16) are introduced, where the films are arranged between the tissue or foam layer and one of the skins, and are made of thermosetting resin. The resin flows towards the open pores to fill the pores, during the pressure of the tissue layer on the core and the pressure of the upper skin on the tissue layer.
