Aircraft Interior Panel Material and Manufacturing Method Therefor

摘要

An aircraft interior panel material includes a core member and surface members attached to both surfaces of the core member. The core member includes a plate member composed of balsa wood and having a rectangular shape and uniform thickness. Both surfaces of the plate member in the thickness direction are flat surfaces. Balsa wood is a light weight natural material whereby environmental impact can be reduced. Both surfaces of the plate member in the thickness direction are impregnated with flame retardant, which reduces the flammability of the balsa wood. Impregnation of the plate member with the flame retardant may be performed by: spraying the flame retardant; by immersing the plate member in the flame retardant; or
upon the plate member being immersed in the flame retardant, by applying a pressure larger than the pressure at the depth where the plate member is immersed or cycles thereof to the plate member.
