Abstract

The webinars examine the history, present capabilities, and future of composites science and technology. The goal of the series is to accumulate the vast knowledge of composites that has been developed over the past 50 years and to make it available to the global composites community. Each webinar is a one-hour Zoom online meeting. It starts with a brief introduction to cdmHUB and the speaker, followed by a 40-45 minutes talk by a world class expert, ended by Q&As between the speaker and audiences.
