Abstract

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 recycle 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 does not purge more than 10scfh through fluid dynamics analysis, and 99% of the resin is removed through thermodynamics analysis. This is done by using a thermocouple to measure the temperature, an oxygen meter to measure the purging of argon, and a scale to measure the change in weight as the resin is removed. The design that meets these criteria has two 20-gauge steel sheet enclosures that fit within each other, and in-between is 2-inch mineral wool insulation. This was manufactured using a CNC plasma cutter and welding. Overall, the outside surface measured to be 50 °C, 5 °C more than what was predicted. The oxygen meter measured 1% oxygen in the system meaning that the purging of argon was lower than 10scfh. Finally, the change of mass between before and after the carbon fiber was in the oven showed to have a change of 0.2g which shows to have a 99% resin removal based on the calculated mass flow rate.
