Summary
Fabrication techniques were developed for producing graded porosity B4C, and for producing aluminum-B4C and epoxy-B4C fuctionally graded materials. The key fabrication aspect was obtaining the graded porosity B4C. The feasibility of producing graded porosity B4C using a grading of carbon densification aid produced from a gradient of furfuryl alcohol carbon precursor was demonstrated. This approach is quite promising, but it was not optimized in the present investigation. Graded porosity B4C materials were produced by a layering approach using different size distributions of B4C powders in the green state, and then densifLing the layered assembly by hot pressing at 1900°C. The hardness of uninfiltrated graded B4C, aluminum infiltrated B4C, and epoxy infiltrated B4C was observed to be similar.
