Abstract:
A densified freeform-fabricated fiber free part produced by the process of:(a) providing a porous fiber free freeform fabricated part and depositing said part into a bath comprising an infiltrant which includes a ceramic precursor or ceramic containing phase and wherein said ceramic or ceramic containing phase originates from a precursor selected from the group consisting of polysilane, polysilazane, silicon oxycarbide (SiOC), poly(methylviylsilane), poly(aluminosilazane, perhydridopolysilazane, poly(borosilazane), polycarbosilazane, poly(siloxane), poly(carbosilane) and mixtures thereof (b) infiltrating the porous freeform fabricated part such that the infiltrant enters at least a portion of the pores resulting in a densified freeform fabricated part; and (c) removing the densified freeform fabricated part from the bath.
