Use of a sandwich panel as fire insulation or fire barrier and a method for continuous fabrication of sandwich elements

摘要

The use of a sandwich panel is described, the core of which consists of a material prepared from a varying number of layers of prepregs of a thermosetting resin containing thermoplastic microspheres and where the outer laminates are of a conventional type, as a fire protection panel. Furthermore, a method for the continuous fabrication of sandwich panels is described. By this method the laminates, in a wet condition, are placed upon the core in a horizontal process.
