The invention concerns a sandwich designed for making multilayer structures resistant to impact and thermal aggressions of the type including a core 2 interposed between an external skin 1 and an internal skin 3. The external skin panel 1 consists of an assembly of at least three layers made integral by sealing or bonding: a first layer 4 made of composite material, a second layer 5 made of a synthetic cellular material with a low thermal conductivity coefficient, a third layer 6 obtained by lamination of a composite material. The second layer 5 consists...
A structural sandwich panel which is resistant to shock and thermal aggression, comprising: an external skin which is directly exposed to said shock and thermal aggression, said external skin consisting of a first external layer of composite material, a second intermediate layer of a cellular synthetic material which has a low thermal conductivity coefficient, a third internal layer of laminated composite material, and a metal sheet interposed between the second intermediate layer and the third internal layer, said layers being integrally joined together...
