Joining Methods For Continuous Fiber Reinforced Thermoplastic Composites In Structural Applications, Andrew Moran
Joining Methods For Continuous Fiber Reinforced Thermoplastic Composites In Structural Applications, Andrew Moran
Electronic Theses and Dissertations
Continuous fiber reinforced thermoplastic (CFRTP) composites have been proposed as an alternative to metals in structural applications. CFRTP composites can be used to create structures that are lighter weight, have better resistance to environmental factors, and have the potential to be recycled. However, one of the main challenges to CFRTP composites is connections between structural members. The goal of this thesis is to investigate the feasibility of joining CFRTP composites to both similar and dissimilar materials through literature review, coupon testing, design of a structural joint, and a small scale laboratory prototype of the joint. To achieve this goal the …
Pressureless Sintering Of Zirconium Diboride With Carbon And Boron Carbide Nanopowder, Eric W. Neuman, Gregory E. Hilmas, William Fahrenholtz
Pressureless Sintering Of Zirconium Diboride With Carbon And Boron Carbide Nanopowder, Eric W. Neuman, Gregory E. Hilmas, William Fahrenholtz
Materials Science and Engineering Faculty Research & Creative Works
Zirconium diboride ceramics with and without carbon and boron carbide nano powder additives were prepared by ball milling with ZrB2 grinding media and pressureless sintering. Additions of up to 1 wt% nano-B4C and 0.5 wt% C were made to the ZrB2 powder. The materials were then sintered between 1800 and 2300 °C for between 90 and 360 min in an Ar/10H2 atmosphere. After sintering at 2200 °C for 90 min, densities ranged from 88.3 to 90.7% for the ZrB2 with 0–1.0% nano-B4C addition. Carbon additions of 0.5 wt% and nano-B4C additions from 0 to 1.0 wt% resulted in densities ranging …
Characterization Of Biochar As A Carbon Regulator In Manure And Environmental Management Applications, Josephine Getz
Characterization Of Biochar As A Carbon Regulator In Manure And Environmental Management Applications, Josephine Getz
Doctoral
Biochar is a product of pyrolysis, which is the thermal decomposition of materials at elevated temperatures (300 - 900 °C) in an oxygen-limited atmosphere. Biochar has been recognized as a potentially vital tool to help reduce the climate change impact. It has been used in the agricultural sector as an addition to reduce greenhouse gas emissions in several animal husbandry settings. The application in the animal sector is an important point to reduce the overall amount of greenhouse gases released as this sector produces many greenhouse gases. Though not in every case a reduction of emissions was the result of …
Carbon Fiber Recycling: Delamination System, Aaron Eastman
Carbon Fiber Recycling: Delamination System, Aaron Eastman
All Undergraduate Projects
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 …
