Improvement in Orientation Predictions of High-Aspect Ratio Particles in Injection Mold Filling Simulations
… injection molded parts provide a light-weight high-strength alternative for use in automobile applications. These composites have enhanced mechanical properties compared to those of pure polymers, if the fibers are oriented in the right direction. One of the major challenges in processing of …

Synthesis and characterization of nanofluids for cooling applications
… industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles and nanotubes) were introduced into the heat transfer fluids to enhance the thermal conductivity of the resulting nanofluids. The aim of this project was to investigate the physico-chemical properties of …

Selection of Thermotropic Liquid Crystalline Polymers for Rotational Molding
… low coefficient of thermal expansion, high tensile strength and modulus, and good impact resistance, which make them desirable for use in the storage of cryogenic fluids. Rotational molding was selected as the processing method for these containers because it is convenient for …

Multiscale micromechanical modeling of the thermal/mechanical properties of polymer/clay nanocomposites
… on particular features of the second-phase "particles"; in particular, the particle volume fraction (f,), the particle aspect ratio (L/t), and the ratio of particle thermal/mechanical properties to those of the matrix. These important aspects of as-processed nanoclay composites require …

Understanding How Tape Casting Titanium Diboride Shifts its Processing-Microstructure-Properties Paradigm Toward New Applications
… of the UHTCs, titanium diboride (TiB2) exhibits high electrical and thermal conductivity that could satisfy the needs of functional ceramic component applications, like battery cathodes, by tailoring its microstructure and architecture. This thesis represents one of the first detailed studies to …

Dynamics of semi-flexible fibres in viscous flow
… speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers. Although these materials have high rigidity, the large aspect ratiomakes the fibres liable to bending during flow. Other high aspect ratio …
