COMPOSITE STRUCTURAL LAMINATE PLATE CONSTRUCTION COMPRISING OUTER METAL LAYERS AND INTERMEDIATE ELASTOMER LAYER

摘要

A structural sandwich plate member (2) formed of outer metal plates (3) and a plastics or polymer core (4) which bonds the outer metal plates (3) together with sufficient strength to transfer shear forces therebetween has a hollow member (1) embedded in the elastomer core to define a void within the elastomer. The hollow member is made of moulded or extruded plastic.
