COMPOSITE MATERIAL STRUCTURAL BODY AND AIRCRAFT TAIL UNIT USING IT

摘要

PROBLEM TO BE SOLVED: To provide an aircraft plane using a composite. material structural body on which a metal thin plate as a surface reinforcing material or a tightningproofing material durable to distorsion due to different thermal expansion coefficients of both of them on the composite material structural body on which the metal thin plate is adhered to cover an integrally molded composite material and a composite material structural body on which a metal thin plate as a lightningproofing material is adhered and to improve maintenance and working efficiency of paint removal, etc., at the time of repair. ;SOLUTION: A metal plate is divided into a plural number of segment metals, and each of the segment metals is arranged with a specified clearance filled with a cushioning material between them on a composite material structural body constituted by fastening the metal plate on a surface of a composite material such as glass fiber reinforced plastic, carbonic fiber reinforced plastic, etc., or on a composite material structural body constituted in a sandwich shape by respectively fastening the metal plate on both surfaces of the composite material in such a way as to sandwich the composite material. Additionally, the composite material structural body constituted as above is applied to an aircraft plane.;COPYRIGHT: (C)2001,JPO
