Abstract

Tubular Si-infiltrated SiCf/SiC composites composed of inner cellular foams and an outer dense ceramic matrix composite (CMC) skin were fabricated by the electrophoretic deposition of matrix phases followed by Si-infiltration for solar receiver applications in concentrated solar energy. Using a combined replica method with the 3D printing of polymeric inks, 3 types of foams were fabricated to examine the permeability and heat transfer properties depending on the structure of the cellular foams. To form a gastight dense skin layer for the SiC fiber-wound cylindrical foam, the electrophoretic deposition of SiC and carbon black particles followed by Si-infiltration at 1550oC were performed. The fabrication process, resulting microstructure, and oxidation behavior of the composites at 1400 and 1600oC in air are explained in Part 1. The thermophysical properties will be explained in Part 2. Overall, this hybrid method is a suitable processing technology for fabricating SiCf/SiC-based solar receivers.
