Abstract
A burn resistant composite article includes at least one composite layer having first fibers within a first organic resin matrix. At least one burn resistance layer is disposed adjacent the at least one composite layer. The burn resistance layer includes second fibers within a second organic resin matrix. The composite layer and the burn resistance layer each have an associated thermal resistance, and the thermal resistance of the burn resistance layer is greater than the thermal resistance of the composite layer.

A burn resistant composite article comprising:
- at least one composite layer including first fibers within a first organic resin matrix, the composite layer having a first thermal resistance;
- and
- at least one burn resistance layer adjacent the at least one composite layer and including second fibers within a second organic resin matrix, the burn resistance layer having a second thermal resistance that is greater than the first thermal resistance of the composite layer.
A gas turbine engine comprising:
- a compressor section having at least one rotatable blade;
- and
- a case located radially outwards from the at least one rotatable blade, the case comprising a composite having at least one composite layer and at least one burn resistance layer adjacent the at least one composite layer, the at least one composite layer including first fibers within a first organic resin matrix and the burn resistance layer including second fibers within a second organic resin matrix, wherein the composite layer has a first thermal resistance and the burn resistance layer has a second thermal resistance that is greater than the first thermal resistance.
A method of manufacturing a burn resistant composite article, comprising:
- (a) forming at least one composite layer including first fibers within a first organic resin matrix, where the composite layer has a first thermal resistance;
- and
- (b) forming at least one burn resistance layer adjacent the at least one composite layer, the burn resistance layer including second fibers within a second organic resin matrix, where the burn resistance layer has a second thermal resistance that is greater than the first thermal resistance.
