Abstract
A graded multilayered composite comprises a metal matrix material having a first side and a second side opposite the first side. A first layer of microspheres is dispersed on the first side of the metal matrix material. A second layer of microspheres is dispersed on the second side of the metal matrix material.

A graded multilayered composite, comprising:
- a sintered metal matrix material, having a first edge on a first side of the sintered metal matrix material and a second edge on a second side of the sintered metal matrix material, opposite the first side, the sintered metal matrix material having a sintered metal matrix throughout the sintered metal matrix material from the first edge to the second edge;
- a first layer of hollow microspheres, located on the first side of the sintered metal matrix material;
- a second layer of hollow microspheres, located on the second side of the sintered metal matrix material;
- and
- one or more cooling channels in the sintered metal matrix material between the first edge and the second edge,
- wherein:
- hollow microspheres of the first layer of hollow microspheres are spatially distributed relative to each other according to a first spatial gradation, each hollow microsphere having a void therein defining a void volume,
- hollow microspheres of the second layer of hollow microspheres are spatially distributed relative to each other according to a second spatial gradation, each hollow microsphere having a void therein defining a void volume,
- the first spatial gradation is based upon one of a number of the hollow microspheres in the first layer of hollow microspheres or a size of the hollow microspheres in the first layer of hollow microspheres, and
- the second spatial gradation is based upon one of a number of the hollow microspheres in the second layer of hollow microspheres or a size of the hollow microspheres in the second layer of hollow microspheres,
- wherein a total void volume fraction of the second layer is less than a total void volume fraction of the first layer.
