The research in ceramic matrix composites (CMCs) is of industrial and national importance. For example, continuous fiber reinforced ceramic composites (CFCCs) have been successfully fabricated by chemical vapor infiltration techniques at the Oak Ridge National Laboratory (ORNL) and industrial companies, such as DuPont, 3M/Delta G, B. F. Goodrich, Amercom, Refractory Composites and B. P. Chemicals Ltd. The CFCCs are being recognized as necessary for high- temperature structural applications. The pertinent applications include heat exchangers, combustors, hot gas filters and boiler components in power generation systems, and first walls and high heat flux surfaces in fusion reactors. The technology for fabrication, characterization, modeling, design, and applications of ceramic composites is of crucial importance for improving US industrial competitiveness in the worldwide market.

A three-year project on "Ceramic Matrix Composites - A Combined Research-Curriculum Development (CRCD) Program" has been supported by the National Science Foundation to integrate the long-standing research advances, achieved by the University of Tennessee (UT), Knoxville, and ORNL, on CMCs into the interdisciplinary undergraduate and graduate level curricula of Materials and Mechanics at UT.

Implementation of New Curriculum

The two courses on CMCs have been developed by the co-principal investigators (Co-PIs), Liaw and Yu, and approved by (a) Materials Science and Engineering (MSE) and Mechanical and Aerospace Engineering and Engineering Science (MAES) Departments, (b) College of Engineering (CoE), and (c) Undergraduate and Graduate Councils at UT. The newly developed undergraduate course - MSE 429/ES (Engineering Science) 429: Introduction to Ceramic Matrix Composites - and graduate course - MSE 528/ES 528: Ceramic Matrix Composites: Materials and Mechanics - are cross-listed under both MSE and MAES departments in CoE at UT, and have three credit hours with one design credit hour for the undergraduate course. The undergraduate course (MSE 429/ES 429) is offered every Spring semester and is a pre-requisite for the graduate course (MSE 528/ES 528), which is provided every Fall semester. Both courses may serve as technical electives for all engineering majors at UT. The titles and descriptions of these two new courses have been published in the 1997 and 1998 editions of UT undergraduate and graduate catalogs.

The two courses were taught by the UT professors and ORNL scientists. Specifically, the curriculum covers lectures, demonstrations, and hands-on experimentation on the mechanics, design, fabrication, characterization, and applications of CMCs. The courses involve two novel approaches: (a) the integration of materials science and mechanics, and (b) the collaboration between a university - UT - and a national laboratory - ORNL. The following summary outlines some of the features of the two courses.
