Abstract
A composite sandwich formed by enclosing a central resilient layer of a soft compressible material between two plate-shaped parts of foamable synthetic material and inserting the assembly into a cavity formed from two shells of prefabricated sheet metal. The resultant composite is subjected to a heat treatment for about 10 minutes at about 200.degree. C. so that the foamable material expands to fill the cavity.
Claims14
A method of producing composite components of sandwich construction, comprising the steps of assembling two shells, each in the form of a prefabricated metal sheet to define a cavity, and two plate-shaped parts of foamable synthetic material with a resilient central layer of a soft compressible material between them in the cavity, joining the two shells at their edges, and subjecting the resulting assembly to a heat treatment of a duration of approximately 10 minutes at a temperature of approximately 200.degree. centigrade.
