<p>PURPOSE:To obtain an extremely lightweight sandwich panel having an embedded member withstanding even a heat cycle test by providing the sandwich panel wherein skin materials made of carbon fiber reinforced plastic is laminated to both surfaces of a core material and an adhesive bonding the skin materials and the flange part of the embedded member. CONSTITUTION:An embedding hole 3 is formed to a sandwich panel 1 having an embedded member 2 and consisting a core material 1a and skin materials 1b, 1c. The insertion part 2a of the embedded member 2 formed from carbon fiber reinforced plastic of the same kind as the skin materials 1b, 1c is inserted in the embedding hole 3. The flange part 2b of the embedded member 2 is bonded to the skin material 1b of the sandwich panel 1 by an adhesive 4 to embed the embedded member 2 in the embedding hole 3. In the same way as a conventional one, the screw of other member is screwed in the screw hole 2c of the embedded member 2. Since the embedded member 2 and the skin materials 1b, 1c are made of a material of the same kind and same in the coefficient of linear expansion, no crack or release is generated even when the sandwich panel is subjected to a heat cycle test.</p> |
