Mineral fibre-based sandwich structure and method for the production thereof

摘要

A sandwich structure ( 2 ) comprising a core ( 20 ) and two facings ( 21, 22 ) between which the core is placed, the core ( 20 ) being formed from a mineral-fiber-based product ( 1 ) obtained by a process involving internal centrifugation combined with attenuation by a high-temperature gas stream, characterized in that the mineral fibers are crimped.
