Five methods of non-destructive material evaluation (NDE) were used to inspect various forms of damage commonly found in aerospace fiberglass composites: voids, edge and sub-surface delaminations, surface burning, and cracking. The images produced by X-ray, X-ray Computed Tomography, terahertz (THz) imaging, ultrasound, and flash IR thermography were analyzed for the detection of defects. Test results and analysis of each NDE method's capabilities provide a comparison study of conventional techniques versus the emerging technology of THz imaging for the non-destructive evaluation of aerospace composite materials. A comparison guide to the five methods' damage detection effectiveness for fiberglass composites is provided by defect type.

In an era increasingly marked by polarized and unproductive political debates, this volume makes the case for a renewed emphasis on teaching speech and debate, both in and outside of the classroom. Speech and debate education leads students to better understand their First Amendment rights and the power of speaking. It teaches them to work together collaboratively to solve problems, and it encourages critical thinking, reasoned and fact-based argumentation, and respect for differing viewpoints in our increasingly diverse and global society. Highlighting the need for more emphasis on the ethics and skills of democratic deliberation, the contributors to this volume-leading scholars, teachers, and coaches in speech and debate programs around the country-offer new ideas for reinvigorating curricular and co-curricular speech and debate by recovering and reinventing their historical mission as civic education. Combining historical case studies, theoretical reflections, and reports on programs that utilize rhetorical pedagogies to educate for citizenship, Speech and Debate as Civic Education is a first-of-its-kind collection of the best ideas for reinventing and revitalizing the civic mission of speech and debate for a new generation of students. In addition to the editors, the contributors to this volume include Jenn Anderson, Michael D. Bartanen, Ann Crigler, Sara A. Mehltretter Drury, David A. Frank, G. Thomas Goodnight, Ronald Walter Greene, Taylor W. Hahn, Darrin Hicks, Edward A. Hinck, Jin Huang, Una Kimokeo-Goes, Rebecca A. Kuehl, Lorand Laskai, Tim Lewis, Robert S. Littlefield, Allan D. Louden, Paul E. Mabrey III, Jamie McKown, Gordon R. Mitchell, Catherine H. Palczewski, Angela G. Ray, Robert C. Rowland, Minhee Son, Sarah Stone Watt, Melissa Maxcy Wade, David Weeks, Carly S. Woods, and David Zarefsky.
