Boeing uses composite components for the 777x aircraft. The production of composite parts results in flashing (excess material) that must be trimmed and "thrown away" as scrap. Boeing is investigating means of recycling these scraps. The method proposed for this project is to delaminate and shred the composite material. 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. This shredding material is pyrolyzed (heated) to decay the resin leaving the ...
