The disclosure is directed to thermal and acoustic blankets for aircraft structures having reduced weight and improved flame spread resistance. In one aspect, the disclosure is directed to a composite laminate comprising in order (a) a polymeric moisture barrier having a thickness from 6.0 to 25.0 micrometers and a UL 94 flame classification of V-0, (b) an inorganic platelet layer having a thickness from 7.0 to 76.0 micrometers and a UL 94 flame classification of V-0 wherein the platelets comprising the platelet layer have an aspect ratio of from 100 to 20,000, and (c) a thermoplastic film layer having a thickness no greater than 25 micrometers, an average elongation to break no greater than 150% and a UL 94 flame classification of V-0. The inorganic platelet layer of (b) comprises platelets in an amount of 100% by weight.
Cette invention porte sur un stratifié composite comprenant, dans l'ordre (a) une barrière contre l'humidité en polymère ignifuge, (b) une couche en lamelles inorganique et (c) une couche de film en matière thermoplastique ignifuge. L'invention porte également sur un matelas d'isolation thermique et acoustique comprenant une âme de matériau fibreux ou de mousse, entourée par le stratifié composite décrit ci-dessus, la couche de film thermoplastique du stratifié composite faisant contact avec et encapsulant l'âme.
