Diab concept for nacelles and spinners

Requests for consistent quality, controlled tolerances as well as environmental regulations have made many nacelle and spinner manufacturers change their production process from hand layup to vacuum infusion.

DIAB Concept for nacelles and spinners

Diab provides core materials specially engineered for the infusion process. Offering excellent strength-to-weight ratio, they are ideal for nacelle roofs, floors and walls. In order to save additional weight and cost, DIAB offers kits with multiple cores that can be customized according to loading requirements.
