Abstract: Over the past decade advances in the design, materials, and manufacturing of thermoset composite materials have expanded rapidly. Nonetheless, aerospace structures have not yet adopted many of these technologies. This can be attributed to the risk averse nature of the engineering community and associated regulatory agencies in this field.

One of the technologies that has recently gained more traction is the use of unitized co-cure structures. Driving this change is the potential for reducing part count, touch time and labor costs. Most of the work to date focuses on thinner structures (~0.15 inch in thickness) resulting in a lack of work on much thicker parts representing wing-like structures.

This study sheds light on a recent large scale wing skin demonstrator built to understand the behavior of a thick co-cure stiffened wing skin. Details regarding the tooling concept, lamination and process development as well as post cure behavior will be discussed.
