Title (EN) FIRE RETARDED ARAMID FIBER-BASED HONEYCOMB
(FR) NID D'ABEILLES À BASE DE FIBRE D'ARAMIDE IGNIFUGÉE
Abstract:
(EN) An alternate resin-coated paper material for use in making honeycomb. The alternate resin-coated paper material is made from a paper that contains from 30 to 50 weight percent aramid fibers and from 50 to 70 weight percent of non-aramid fibers. A fire retarded phenolic resin is incorporated into the paper to make it self-extinguishing in less than 10 seconds with a self-extinguishing burn length of less than 12 inches when exposed to a 12-second vertical flame in accordance with the vertical bum test requirements set forth in 14 C.F.R. Part 25.583. The fire retarded phenolic resin includes a phenol formaldehyde resin and a phosphorous-containing fire retardant.
(FR) L'invention concerne une variante de matériau de papier recouvert de résine destiné à être utilisé dans la fabrication de nids d'abeilles. La variante de matériau de papier recouvert de résine est réalisée à partir d'un papier qui contient de 30 à 50 pour cent en poids de fibres d'aramide et de 50 à 70 pour cent en poids de fibres non constituées d'aramide. Une résine phénolique ignifugée est incorporée dans le papier de façon à le rendre auto-extinguible en moins de 10 secondes avec une longueur de combustion d'auto-extinction inférieure à 12 pouces lorsqu'il est exposé à une flamme verticale pendant 12 secondes conformément aux exigences du test de combustion verticale établies dans 14 C.F.R. section 25.583. La résine phénolique ignifugée comprend une résine à base de phénol-formaldéhyde et un produit ignifuge contenant du phosphore.
