A Comprehensive Study on Moisture Absorption of Thermosetting Polymers, Micro- and Nanocomposites, and Foams
Guloglu, Gorkem Egemen (2018-12-14)Molecular diffusion is the transfer or movement of individual molecules through a fluid or a solid by means of random, individual movements of the molecules. Even though moisture can diffuse into all materials above the ... -
Fabricating High-Quality Structural Composite Laminates and Tailoring Their Surface Microstructure by Applying Magnetic Pressure and Magnetic Field
Pishvar, Maya (2019-05-10)Advanced fiber reinforced polymer (FRP) composites are widely used in structural applications due to their high specific strength and stiffness. Generally, high-quality, advanced FRP composites are produced using an ... -
Fabrication, Characterization and Modeling of Aligned Polyacrylonitrile-Based Electrospun Carbon Nanofibers
Demirtas, Mehmet Selim (2018-08-02)Electrospinning is widely used to produce carbon nanofiber from polyacrylonitrile (PAN). The alignment of fibers may vary depending on electrospinning condition. In this study, an electrospinning setup is developed to ... -
Improving the Quality of Laminates in Liquid Composite Molding Using Magnetic Compaction: Experiments and Process Model
Amirkhosravi, Mehrad (2019-05-10)Despite the extensive use of liquid composite molding (LCM) processes such as wet lay-up vacuum bagging (WLVB) and vacuum assisted resin transfer molding (VARTM) in composite manufacturing, they have two major drawbacks. ... -
INVESTIGATION OF ELECTROSPINNING PROCESS PARAMETERS AND STUDIES OF STABILIZATION KINETICS OF POLYACRYLONITRILE-BASED ELECTROSPUN CARBON NANOFIBERS
Barua, Bipul (2015-08)Carbon nanofibers produced by electrospinning brings many advantages over carbon fibers made from conventional spinning methods as they are expected to possess less structural defects, superior mechanical performance, and ... -
Manufacturing and Microstructural Modeling of Geometrically Complex Composite Components Produced by Bladder Assisted Composite Manufacturing (BACM)
Anderson, Jacob (2013-12)In the first part of the dissertation a new manufacturing method, Bladder Assisted Composite Manufacturing (BACM), to fabricate geometrically complex, hollow polymeric composite parts is presented. The BACM process utilizes ... -
The Synergistic Effects of Prepreg Humidity Exposure, Fabrication Pressure, and Hydraulic Fluid Absorption on Microstructure and Mechanical Properties of High-Performance Composite Laminates
Hurdelbrink, Keith II (2017)Research and technological enhancements over the past several decades have yielded vast improvements in the area of fabricating high quality composite laminates. Process-induced defects, such as microvoids, however remain ...
