Abstract:

A method for fabricating an infiltrated object of a desired shape having a high volume fraction of infiltrant using an additively manufactured preform. Using an additive manufacturing technique, the preform is formed with graded macro-porosity. When infiltrated, the void volume of the macro-porosity is filled with infiltrant Optionally, the void volume may be varied across the profile of the object to create a gradient of mechanical properties in the infiltrated object.
