Composite panel for aircraft interior fittings, especially trim, has layer of rigid plastic foam and second layer of resin-impregnated fabric between wood veneer and first layer of resin-impregnated fabric

摘要

The composite panel, comprising a central honeycomb core (1) covered on both sides with a layer of resin-impregnated fabric (2) and a thin wood veneer (5) on at least one side, has a layer of a rigid plastic closed-cell foam (3) and a second layer of resin-impregnated fabric (4) between the veneer and the first layer of resin-impregnated fabric, so that the foam layer lies between two layers of fabric. The composite panel, comprising a central honeycomb core (1) covered on both sides with a layer of resin-impregnated fabric (2) and a thin wood veneer (5) on at least one side, has a layer of a rigid plastic closed-cell foam (3) and a second layer of resin-impregnated fabric (4) between the veneer and the first layer of resin-impregnated fabric, so that the foam layer lies between two layers of fabric. The different layers of the panel are assembled and joined together by applying heat (up to about 135 degrees C) and pressure (1 - 3 bars) in a single operation lasting about one hour.
