A repair patch and method for effecting repair to damaged, non-stressed aircraft structure

摘要

A apparatus and method for effecting repair to damaged, nonstressed aircraft structure is described. A sheet of material comprised of woven glass cloth impregnated with a resin cured under temperature and pressure forms the basic patch. One side of the patch has a Tedlar® overlay attached to the sheet face in the preferred embodiment. This patch material meets the Federal Aviation Regulations (FAR 25.855) which is required to provide for fire resistant material on transport aircraft. A pressure sensitive film is bonded to the side opposite the Tedlar® overlay. This combination of glass sheet and pressure sensitive film is pressure bonded to the damaged structure and further held in place by mechanical fasteners which can withstand a temperature of at least 1,700 degrees Fahrenheit.;One of the primary applications of this invention is in the cargo liner repair of transport aircraft. A fire in the cargo bay must be contained in that area and not allowed to spread to the aircraft due to a damaged cargo liner.
