Jcati Carbon Fiber Recycler: Oven Enclosure, Margarita Romero
Jcati Carbon Fiber Recycler: Oven Enclosure, Margarita Romero
All Undergraduate Projects
Central Washington University partners with Boeing and is funded by the Joint Center of Aerospace Technology Innovation (JCATI) to develop a mechanism that takes carbon fiber wing trimmings from Boeing that are resin coated and recycles carbon fiber. This is done by crushing the wing trimmings and then putting it into a 500°C oven to melt off the resin. This project focuses on the enclosure for the oven and making sure precautions are met such as having the outside surface be less than 45c through heat transfer analysis, argon fills enclosure in 13 minutes through fluid dynamics analysis, and 99% …

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 30-40 percent delamination with one pass through the system, and …

All Undergraduate Projects
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 …

During construction of Boeing’s aircrafts, carbon fiber reinforced composites are used as the primary material for the wings of the aircraft. Excess material during the manufacturing process is trimmed and discarded as waste. Although there is no viable process thus far, these trimmings have the potential to be recycled and reclaimed to be used in various other manufactured products. The trimmings of carbon fiber composite are approximately 10-12 layers of material bonded together. This project focuses on delaminating the trimmings into individual layers so that the carbon can be pyrolyzed from the bonding resin. In order to separate the layers …

A great deal of composite waste is generated in the construction of wings for the Boeing 777. These carbon fiber “wing trimmings” are currently being disposed of in a landfill. These carbon fiber boards are made of several layers laminated together, making them very rigid and hard to recycle. This report proposes a method to delaminate the layers of these composite wing trimmings using a hydraulic press and a V-shaped steel die so that they may be more easily shredded and thus recycled. A top, “male” die with two points is pressed into a bottom, “female” die with three points …
Weather Balloon Payload Box, Shellbie Liberty
Weather Balloon Payload Box, Shellbie Liberty
All Undergraduate Projects
A payload box holding a self-rotating camera was constructed to go on a weather balloon that will document the upcoming solar eclipse on August 21, 2017. A group of physics students, and the paper’s author, are working under Dr. Darci Snowden on the CWU Near Space Observation Team for research dedicated to the eclipse in Oregon. Various projects, including the payload box, are being designed to go up on a high altitude weather balloon. The payload box was designed and constructed to withstand the impact force of falling from 120,000 ft. This was done so the box could be reusable …
