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 monazite based pre-ceramic slurry;
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.

Abstract
A flexible insulation blanket having a ceramic matrix composite (CMC) outer layer, and a method of producing a flexible insulation blanket having a smooth, aerodynamically suitable, outer surface by infiltrating ceramic material within the outer ceramic fabric layer of the flexible insulation blanket and curing the ceramic material to form a CMC layer. The CMC layer is cured while the blanket is under compression such that the resulting CMC layer has a smooth surface.

20. A method of constructing a ceramic matrix composite (CMC) infiltrated flexible insulation blanket having a smooth surface, comprising:
-
laminating an outer ceramic fabric layer, a batting layer, and a inner ceramic fabric layer;
sewing the laminate to form a quilted blanket having an outer surface corresponding to the outer fabric layer and an inner surface corresponding to the inner fabric layer;
applying an uncured monazite based ceramic matrix material to the outer surface of the blanket;
placing the blanket under pressure in the direction of thickness of the blanket;
curing said ceramic matrix material to form a CMC layer with the outer fabric layer of the blanket;
releasing said pressure; and
sintering the CMC layer of the blanket.
