摘要

Two and three dimensional fiber preforms produced by textile forming techniques have been used successfully for reinforcing ceramic-based composites. The focus of this paper is on the design of textile preforms for reinforcing ceramic matrix composites. The research work consisted of the following tasks: (1) identification of typical loading conditions on composite structural elements; (2) determination of the requirements on the orientation and volume content of fiber reinforcement; (3) identifying the fiber preforms suitable for each loading condition; (4) identifying the preforming technologies available for producing the preforms; (5) analysis and modeling of the thermo-mechanical behavior of the textile composites, using the concepts of micro- and macro-cells; and (6) characterization of textile composite performance.
