Abstract:
1. A method of producing a flexible insulation blanket having a ceramic matrix composite infiltrated layer with a smooth surface, said method comprising: layering, respectively, an outer ceramic fabric layer, a batting layer, and a inner ceramic fabric layer; quilting said layers to form a flexible insulation blanket; infiltrating said outer fabric layer of said blanket with a pre-ceramic slurry; preventing the pre-ceramic slurry from penetrating into the batting layer so that substantially no absorption of the pre-ceramic slurry occurs in the batting layer; compressing the blanket in the direction of thickness of the blanket by applying pressure to said outer layer of the blanket with a smoothly surfaced plate; curing said pre-ceramic slurry; and sintering the infiltrated outer ceramic layer to form a ceramic matrix composite layer.
