SOURCE 2022 has ended
The mission of the Symposium of University Research and Creative Expression (SOURCE) is to provide a university-wide forum for Central Washington University (CWU) students, encouraging equity, diversity, and inclusivity, representing all disciplines and experience levels, to present their mentored research, scholarship, and creative works in a juried environment that meets professional conference standards and expectations.

The 2022 SOURCE program is hybrid. Pre-recorded virtual talks are colored green and can be watched anytime. Live/in-person sessions with Zoom access can be found in the daily schedule. Thank you for joining us!

Feedback form is now closed.
This project is a potential solution to keep the carbon fiber waste from airplane manufacturing to a minimum, sponsored by the Joint Center for Aerospace Technology Innovation (JCATI). The design and assembly will be scalable for future industry application. The overall design of the whole carbon fiber recycler consists of a crusher, shredder, and oven. This report is on the caron fiber shredder module. The shredder is tasked with being able to shred the delaminated carbon fiber scrap that directly comes from the crusher. The operation must produce shreds in the proper size to be gathered and delivered to the oven module. During the manufacturing process, engineering methods were used to find proper requirements of the design. The material strength of carbon fiber is calculated with the goal of finding the required force to yield thus breaking the material. The dynamic calculations are done to find the moment of inertia required to reach such a force. Lastly the static calculations find the requirements of the frame and housing plates to be sure that all reaction forces are supported. Multiple tests of the carbon fiber recycler were conducted. The results showed that the shredder produced fibers measuring half an inch on average. With multiple operations the shredder never bound when cutting the carbon fiber. The lowest speed it experienced was 413 RPMs. The last test done was on the vibrations during operation. While cutting carbon fiber the maximum deviation was 0.0075-inch. In conclusion, the device was successful and safe to operate.
