Composite Mysteries: Decade-Old Challenges Remain Unresolved Summary

History teaches us that advanced composites, as applied to aerospace structures, have been around since the 1940s.  Yet, the big push for understanding composites and applying them where they would have the biggest benefit, started in the 1960s and 1970s where the foundations of the structural analysis of composite structures were laid.  At that time, some of the main issues associated with composites, such as prediction of failure and understanding of damage creation and growth, were identified and many great researchers spent a lot of time working on them.  Since then, tremendous progress has been made and usage of composites has reached unprecedented levels.  Yet, despite the progress, many of the very same issues, which forced (and force) industry to spend huge amounts of money and time in testing, persist and the gap between what industry needs and what academia focuses on is widening.  Worse yet, because of these issues, industry is reluctant to explore new concepts and push the design envelope further.  The eight most "stubborn" challenges, with the biggest impact on industry applications, are identified and briefly discussed.
