JULY 2016 26 CompositesWorld WORK IN PROGRESS Industrializing the process Clean Sky 2 OUTCOME is, in fact, underway. FIDAMC and its partners want to improve and scale up the process, produce a larger stifened wingskin panel, incorporate it into the wing of a CS2 regional aircraft, and fight test it in 2020. Several additional items are on the group's agenda, among them continued improve- ment in layup productivity (wider tapes or more tapes layed, simultaneously). Also, an eight-tow head will be incorporated into the existing MTorres machine, along with new advances in laser optics. Te technology improvements will be used to produce parts with more complex geometries. Diferent stringer styles also will be produced, using rollforming and even autoclave consolidation methods. Improved surface treatment for bonding of the stringer feet to the skin, including plasma, will be investigated. Lastly, the group will expand on repair strategies that it has already researched. Te manufacturing trials have demonstrated the feasi- bility of in-situ repairs that might be extrapolated for in-service use through the development of a reliable blanket heating system with a portable repair technology. "It would be interesting to study other bonding technologies for in-service repairs, with local heating systems and fusion bonding techniques, bulk heating or adhesive bonding," says Rodriguez. OUTCOME's goal is to achieve technology readiness level [TRL] 6 for the in-situ ther- moplastic layup process. Concludes Rodri- guez, "Termoplastics ofer damage toler- ance, chemical resistance, infnite shop life, weldability, ability to recycle and shorter manufacturing cycles compared to thermo- sets. Not only are material properties high, but there is potential for faster processing, lower lifecycle costs and environmental sustainability."
