Method of fabricating a refractory metal ceramic matrix composite

Abstract

A method of fabricating a refractory metal ceramic matrix interpenetrating phase harsh environment capable composite is provided. The method includes forming a reinforcing phase by additive manufacturing and introducing a matrix material to the reinforcing phase. The step of introducing the matrix material may be performed by additive manufacturing or a densification process. The reinforcing phase may be a lattice formed of metal or a ceramic, and the matrix material may be a ceramic or a metal. Alternatively, the reinforcing phase formed by additive manufacturing is a laminate layer, and the matrix material introduced to the reinforcing phase is a laminate layer deposited on the reinforcing phase by additive manufacturing in a plurality of alternating layers. A refractory metal ceramic matrix composite is also disclosed. The refractory metal ceramic matrix composite includes a lattice formed by additive manufacturing, and a matrix material deposited in the lattice.
