Accurate Characterization of Moisture Absorption in Polymeric Materials
Hamidi, Youssef (SPE Plastics Research Online, 2017)The importance of using the exact solution of the hindered diffusion model is demonstrated on experimental data from a nanoclay/epoxy composite. -
Dispersion Characterization of Nanoclay in Molded Epoxy Disks by Combined Image and Electron Microbeam Analysis
Hamidi, Youssef (Journal of Engineering Materials and Technology, 2008)The state of nanoclay dispersion in a molded epoxy disk and its effects on the thermo-mechanical properties of the resulting nanocomposite are analyzed. A commercially available nanoclay, Cloisite® 25A, is mechanically ... -
Effect of Fiber Content on Void Morphology in Resin Transfer Molded Composites
Hamidi, Youssef (Journal of Engineering Materials and Technology, 2009)Effect of fiber volume fraction on occurrence, morphology, and spatial distribution of microvoids in resin transfer molded E-glass/epoxy composites is investigated. Three disk-shaped center-gated composite parts containing ... -
Effect of Nanoclay Content on Void Morphology in Resin Transfer Molded Composites
Hamidi, Youssef (Journal of Thermoplastic Composite Materials, 2008)Effects of nanoclay content on morphology and spatial distribution of voids in resin transfer molded nanoclay/E-glass/epoxy composite disks are investigated. Closite®25A nanoclay loads of 2, 5, and 10wt% are mixed by ... -
Fast Recovery of Non-Fickian Moisture Absorption Parameters for Polymers and Polymer Composites
Hamidi, Youssef (Polymer Engineering and Science, 2016)Moisture absorption is known to detrimentally affect the mechanical integrity and durability of polymeric materials. Consequently, accurately characterizing the moisture diffusion into these materials is critical when ... -
Filtration and Breakdown of Clay Clusters During Resin Transfer Molding of Nanoclay/Glass/Epoxy Composites
Hamidi, Youssef (Journal of Composite Materials, 2008)Dispersion of nanoclay clusters during resin transfer molding of nanoclay/glass/epoxy disks is investigated. In addition to a center-gated disk containing only 14% glass fibers, three nanocomposite disks are fabricated ... -
Performance of Glass Woven Fabric Composites with Admicellar-Coated Thin Elastomeric Interphase
Hamidi, Youssef (Composites Interfaces, 2017)Adequate stress transfer between the inorganic reinforcement and surrounding polymeric matrix is essential for achieving enhanced structural integrity and extended lifetime performance of fiber-reinforced composites. The ... -
Process Induced Defects in Liquid Molding Processes of Composites
Hamidi, Youssef (International Polymer Processing, 2017)Liquid Composite Molding (LCM) processes are cost efficient manufacturing alternatives to traditional autoclave technology for producing near-net shape structural composite parts. However, process induced defects often ...
