Jcati Composite Delaminator, Payden Coffman

All Undergraduate Projects

Improvements need to be made to the existing delaminator system designed to crush proprietary Boeing 777 composite material. The current design incorporates a hydraulic system to achieve the high loads needed to separate material layers. The new system will need to be able to apply the same loads while at the same time allowing for a constant feed of material through the system. To achieve this, a “gear-like” crushing system will be implemented that will apply a high enough radial load into the material that will achieve delamination equal or greater than the previous design while at the same time …

Composite Recycler: Frame, Alfonso Olivera

All Undergraduate Projects

How can composites be recycled? The Composite Recycler is an ongoing project that started in September 2017. The purpose of this project was to create a machine that will delaminate the composites, cut them, and heat them up to separate the resin from the composites so they can be recycled. A group was put together for the 2018-2019 academic year to further the project as a whole improve the operation of the device. The existing base was used as well as the cutter and the power sources. The upgrades included; a housing to support the transport rollers and changing from …

Repurposing Carbon Fiber Composite Through Mechanical Means, Jason Morrow

All Undergraduate Projects

Composite waste from the 777 aircraft is a growing concern for Boeing and amounts to an excess of 600,000 pounds of highly valuable carbon fiber being thrown away. Reclaiming this material has been a long sought-after goal of Boeings as the current solution is ever expanding landfills. The two current methods of recycling composite waste are chemically and mechanically processing. The focus of this paper will be demonstrating the feasibility of mechanically processing composite waste to increase storage efficiency before chemically treating to reclaim the actual carbon fibers. This paper provides a two-stage solution for the recycling question. The first …

Title and Author: Composite Cutting Device by Misha Minasyan (Mechanical Engineering Technology)

As the aerospace industry innovates, so does the material that is being used. No longer are airplane manufacturers like Boeing depending on only various metals for making their wings. A transition over the past few years has been made to using composite materials because of there light weight and strength. The issue that composite material brings is that it cannot be recycled without processing. The current 777X made by Boeing has transitioned to used composite to manufacture their airplane wings.
