Biography

Dr. Gowayed is the Chair of the Department of Fiber Science and Apparel Design. His research work focuses on developing computational models and experimental techniques to further the understanding of the mechanical and thermal behavior of polymer and ceramic matrix composites. He has been successful in forming research consortia with universities, industries, national laboratories, and small businesses, and leading research efforts funded by NASA, AFRL, DoE, DoC, DHS, Pratt & Whitney, Rolls-Royce and Goodrich. He documented his research efforts in many refereed publications, presentations, book chapters and most recently a book on Ceramic Matrix Composites. He also compiled some of his research work into the computer algorithm “Graphical Integrated Numerical Analysis pcGINA©” which is currently used by many aerospace companies and government agencies to design polymer and ceramic matrix composites.  

He taught classes in mechanics of composite materials and fabric structures for Seniors and Graduate Students, Introduction to Engineering for Freshmen, and Research Methods for International Graduate Students. He is interested in novel teaching methods and cross-disciplinary educational paradigms and developed and taught non-traditional learning experiences. 

Submitted pre-application to DoE on "Characterization of defects and variabilities in coated CMC tubes using Resonant Ultrasound Spectroscopy," with Vibrant Corporation and  United Technologies Research Center (not funded)

FSAD 6860: Mechanics of Fibrous assemblies and their composites

Course description: This class introduces mechanics of fibers, yarns and fabrics in a way that allows students to grasp the role of each constituent and their interaction in the overall response of fabrics under load. Types of fibrous composites will be discussed, and advantages and disadvantages of each type articulated to bring attention to their role as important structural materials. Mechanical models for fibrous composites will be introduced.
