Abstract

The production of composite wings at Boeing causes carbon fiber waste and CWU Mechanical Engineering Technology students have been tasked in designing a carbon fiber recycling system. This project was brought forth and funded by the Joint Center for Aerospace Technology Innovation (JCATI). There are three subsystems that make up the carbon fiber recycling system, the delamination system, shredding system and the oven. The purpose of this project was to increase the efficiency and effectiveness of the delamination system of the carbon fiber recycling system. The old system reached approximately 50 percent delamination with one pass through the system, and the center of the housing deflected near 0.125 inch during the crushing process. To increase the effectiveness of the delamination system, the shear modulus of the carbon fiber drove the design requirements to ensure enough crushing force would be applied. The shear modulus was able help determine the needed torque and crushing force of 8750 pounds. In order to meet the needed torque, the input torque was tripled by a group member and another set of crushing wheels was added to the design. With the carbon fiber strips being crushed twice a greater percentage of delamination will be reached. To ensure the housing deflected less, a more rigid frame was designed made of 14 angle iron members welded together. Initial testing has found that the carbon fiber strips now reach 90 percent delamination, and the housing only deflects .05 inches at the center of the frame.
