Window panel for an airframe and method of producing same

摘要

The present invention provides a window panel (1) for a body structure of a vehicle (V), especially an airframe of an aircraft or spacecraft, comprising: a first skin (2) which extends over a first side (3) of the panel (1) to form an outer skin of the vehicle body structure; a second skin (4) which extends over a second side (5) of the panel (1) to form an inner skin of the vehicle body structure; and a core (6), especially a foam core, located between and covered by the first and second skins (2, 4) in a sandwich structure. The window panel (1) includes at least one window aperture (7) formed through the first layer (2), the core (6), and the second layer (4). The core (6) may be confined to or extends over a limited extent, region or part of the panel (1). Thus, the first skin (2) and/or the second skin (4) may extend over or cover/s a greater area of the panel (1) than the core (6).
