Abstract:

Large scale mechanical systems for impregnating and positioning composite materials are now permitting efficient manufacturing of composite hulls to 60 meters 200 ft and greater. Recreational, commercial, and military vessels fabricated from composite materials are gaining acceptance around the world however, processing of thermosetting resins and fiber reinforcements in quantities exceeding 90,000 kg 200,000 lbs per unit presents a new set of challenges to production engineers responsible for maintaining quality control. Impregnation systems are currently being used at several mine-hunter production shipyards world-wide. Large-to-medium sized recreational yachts are also in production with impregnation systems. This paper will review some past and current impregnator installations, the selection process used for choosing the systems, and production engineering factors.
