ABSTRACT:
A flame penetration blocker for fuselages which is a laminate of a 100 to 600 g/m.sup.2 mica paper having laminated on one or both sides of it 30 to 300 g/m.sup.2 needled fabric layers made of flame-retardant fibers. The adhesive effect of the laminate is produced by a partially cross-linked, latently adhesive, temperature resistant binding agent incorporated into the mica paper itself. The laminate is made by adhesive bonding one or both surfaces of a mica paper of the named type with a needled fabric layer under pressure and at a temperature that does not trigger the final cross-linking of the binding agent.
