The Boeing Company gave Central Washington University an opportunity for students to research and come up with an idea to reduce costs and landfill waste caused by the trimmings from the 777x composite wing pieces. The engineering and manufacturing for this project is about transporting composite material through to the delamination and chipper process. The delamination process uses a ram to press two claw shaped devices together that bends and deforms the material in opposite directions. The chipper process uses counter rotating saw blades spaced 1/8” apart to produce small shredded material. It is important for this newly designed feed control to move the composite material at a steady speed and grip the material with enough force to move it towards the delamination and chipper process. It should function without jamming, breaking, and ejecting the material improperly. The feed control has shafts with sharp grooves, turning the feed control at a steady 10 inches per minute making the whole mechanism function more efficiently. The system is designed to run the material through for 5 seconds, stop 14 seconds for the ramming process and repeat. The feed control mechanism manufactures the shafts for best fit, putting those parts together and manually moving the feed. Testing showed that the composite material moving along to the delamination process works, properly holding the material and preventing jams. The volume of material that could be fed through the system was 5 cubic inches per minute.
