Abstract
A multilayered material system includes at least one of a liner sheet and a cellular core, and a multilayered composite joined to the at least one of a liner sheet and a cellular core. The multilayered composite includes hollow microspheres dispersed within a metallic matrix material.
Claims20
A method for manufacturing a multilayered composite, comprising:
- providing a first layer of a first powder having first hollow microspheres dispersed therein;
- providing a second layer of a second powder over the first layer of the first powder, the second layer of the second powder having second hollow microspheres dispersed therein;
- and
- heating the first layer of the first powder and the second layer of the second powder,
- wherein at least one of:
- (i) the first layer of the first powder comprises a first metallic powder composition, the second layer of the second powder comprises a second metallic powder composition, and the second metallic powder composition is compositionally different from the first metallic powder composition;
- and
- (ii) a thermal microstructural stability point of the second layer of the second powder is greater than a thermal microstructural stability point of the first layer of the first powder.
