Claims26
A laminated matrix composite comprising:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of at least one material deposited on said reinforcement phase, wherein each layer has an arithmetic mean thickness of less than 0.5 μm.
A laminated matrix composite comprising:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of two matrix materials, wherein the arithmetic mean of the thicknesses of said layers is between 0.005 μm and 0.1 μm, and wherein each of said matrix materials is alternated so that each layer is of a different composition than any adjacent layer.
A process for producing a laminated matrix composite comprising the steps of
- (a) forming a reinforcement phase;
- and
- (b) successively coating said reinforcement phase with a plurality of layers of two or more matrix materials, wherein the arithmetic mean of the thicknesses of said layers is between about 0.005 μm and about 0.1 μm.
A laminated matrix composite consisting essentially of:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of at least two materials deposited on said reinforcement phase, wherein each of said layers is less than 0.5 μm thick.
A laminated matrix composite consisting essentially of:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of two matrix materials each between about 0.005 μm and about 0.1 μm thick, wherein each of said matrix materials is alternated so that each layer is of a different composition than any adjacent layer.

A laminated matrix composite consisting essentially of:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of at least two materials deposited on said reinforcement phase, wherein each of said layers is less than 0.5 μm thick, and wherein each of said materials alternated so that each layer has a different property than any adjacent layer.
A laminated matrix composite comprising:
- (a) a reinforcement phase;
- and
- (b) a plurality of layers of at least one material deposited on said reinforcement phase, wherein each layer has an arithmetic mean thickness of about to 1.0 μm or less;
- and
- (c) wherein the material is not silicon carbide or boron carbide.
