1. A multilayer laminate for use as a flame barrier in an aircraft comprising
(i) a polymeric film layer having a temperature resistance of at least 200 degrees C. for at least 10 minutes, (ii) an adhesive layer having an areal weight of from 2 to 40 gsm having an activation temperature of from 75 to 200 degrees C., (iii) an inorganic refractory layer having a dry areal weight of 15 to 50 gsm and residual moisture content of no greater than 10 percent by weight, and (iv) aramid paper comprising from 50 to 90 weight percent of aramid fibers and from 10 to 50 weight percent of meta-aramid binder;
wherein the inorganic refractory layer of (iii) comprises platelets of vermiculite in an amount of at least 85% by weight. |
