Download or read book Fundamentals of Fiber Orientation written by Charles L. Tucker III and published by Carl Hanser Verlag GmbH Co KG. This book was released on 2022-03-14 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers reinforced with discontinuous fibers have a wide range of important applications such as in automotive parts and business machines. The flow that occurs during processing of these materials creates a complex but repeatable pattern of fiber orientation, which plays a key role in achieving the desirable mechanical properties these materials can offer. The primary focus of this unique book is fi ber orientation: how to describe it mathematically, how to measure it experimentally, and how to predict it using models available in commercial software. The book also covers the description, measurement, and modeling of fiber length, another important variable that can be predicted by commercial software. The connection between fiber orientation and mechanical properties is explained, as is the relationship between fiber orientation and rheological properties in the fluid state. “Fundamentals of Fiber Orientation” focuses on the models used in current engineering practice, but also discusses topics from current research that could transition to engineering practice soon. For practicing engineers, this book teaches the fundamentals needed to understand data, set up meaningful simulations, and interpret results. The book provides a thorough, organized overview of the field, and will also be a valuable resource to those undertaking research in this area. Free MATLAB software implementing the models discussed in the book is provided online.

Download or read book Mass Transfer and Rheology of Fiber Suspensions written by and published by . This book was released on 2013 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rheological and mass transfer properties of non-Brownian fiber suspensions are affected by fiber characteristics, fiber interactions, and processing conditions. In this thesis we develop several simulation methods to study the dynamics of single fibers in simple shear flow, as well as the rheology and mass transfer of fiber suspensions. Isolated, rigid, neutrally-buoyant, non-Brownian, slightly curved, nonchiral fibers in simple shear flow of an incompressible Newtonian fluid at low Reynolds number can drift steadily in the gradient direction without external forces or torques. The average drift velocity and direction depend on the fiber aspect ratio, curvature and initial orientation. The drift results from the coupling of rotational and translational dynamics, and the combined effects of flipping, scooping, and spinning motions of the fiber. Irreversible fiber collisions in the suspensions cause shear-induced diffusion. The shear-induced self-diffusivity of dilute suspensions of fibers increases with increasing concentration and increasing static friction between contacts. The diffusivities in both the gradient and vorticity directions are larger for suspensions of curved fibers than for suspensions of straight fibers. For suspensions of curved fibers, significant enhancements in the diffusivity in the gradient direction are attributed to fiber drift in the gradient direction. The shear-induced self-diffusivity of concentrated suspensions of fibers increases with increasing concentration before fiber networks or flocs are formed, after which the diffusivity decreases with increasing concentration. The diffusivity increases with increasing fiber equilibrium bending angle, effective stiffness, coefficient of static friction, and rate of collisions. The specific viscosity of fiber suspensions increases with increasing fiber curvature, friction coefficient between mechanical contacts, and solids concentration. The specific viscosity increases linearly with concentration in the dilute regime, and increases with the cube of the concentration in the semi-dilute regime. Concentrated fiber suspensions are highly viscous, shear thinning, and exhibit significant yield stresses and normal stress differences. Yield stresses scale with volume concentration and fiber aspect ratio in the same way as that observed in experiments. The first normal stress difference increases linearly with shear rate. The shear-induced diffusivity increases linearly with the derivative of the particle contribution to stress for dilute suspensions with respective to concentration. This correlation between rheology and shear-induced diffusion makes it possible to predict diffusivity from easily measured rheological properties.

This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research activities are focused on modeling of polymeric liquid crystal (LCP) flows. We first summarizes our comprehensive studies on the shear and elongational flow with an imposed velocity field. This includes a complete characterization of the orientational equilibrium and their bifurcation behavior as well as the detailed study on the orientation dynamics with respect to both types of flows. In particular, biaxial patterns and their dynamics are treated carefully. We then report on the work on the modeling of fiber spinning processes of thermotropic liquid crystal polymers, where new models along with an extensive study for fiber flows of thermotropic liquid crystals are presented. The study on the influence of microstructure on the capillary instability of liquid crystal jets follows. Finally, we report on some long wave stability analysis for ideal liquid jets of LCPs and the progress on some ongoing projects.
