Book Description
The purpose of aligning short fibers in a fiber-reinforced material is to improve the mechanical properties of the resulting composite. Aligning the fibers, generally in a preferred direction, allows them to contribute as much as possible to reinforcing the material. The first edition of this book detailed, in a single volume, the science, processing, applications, characterization and properties of composite materials reinforced with short fibers that have been orientated in a preferred direction by flows arising during processing. The technology of fiber-reinforced composites is continually evolving and this new edition provides timely and much needed information about this important class of engineering materials. Each of the original chapters have been brought fully up-to-date and new developments such as: the advent of nano-composites and the issues relating to their alignment; the wider use of long-fiber composites and the appearance of models able to capture their orientation during flow; the wider use of flows in micro-channels in the context of composites fabrication; and the increase in computing power, which has made relevant simulations (especially coupling flow kinematics to fiber content and orientation) much easier to perform are all covered in detail. The book will be an essential up-to-date reference resource for materials scientists, students, and engineers who are working in the relevant areas of particulate composites, short fiber-reinforced composites or nanocomposites. - Presents recent progress on flow-induced alignment, modelling and design of fiber and particulate filled polymer composites - Discusses important advances such as alignment of CNTs in polymer nanocomposites and molecular alignment of polymers induced by the injection molding process in the presence of fillers such as short fibers - Presents fiber interaction/diffusion modelling and also the fiber flexure/breakage models

Book Description
This book provides a review of the current understanding of the behavior of non-spherical particle suspensions providing experimental results, rheological models and numerical modeling. In recent years, new models have been developed for suspension rheology and as a result applications for nanocomposites have increased. The authors tackle issues within experimental, model and numerical simulations of the behavior of particle suspensions. Applications of non-spherical particle suspension rheology are widespread and can be found in organic matrix composites, nanocomposites, biocomposites, fiber-filled fresh concrete flow, blood and biologic fluids. - Understand how to model and predict the final microstructure and properties of particle suspensions - Explores nano, micro, meso and macro scales - Rheology, thermomechanical and electromagnetic physics are discussed

Book Description
The study of polymeric particle suspensions has been the subject of a number of past experimental and theoretical studies. However, fundamental questions about suspension rheology and shear flow-induced microstructural effects remain. First, a quasi-analytical study is presented that gives the first theory-based predictions on the effects of finite polymer relaxation time on rheological properties. In a constant viscosity, low polymer concentration fluid, the addition of particles is found to have a strong shear thickening effect on the first normal stress difference coefficient and the shear viscosity. In contrast, the second normal stress difference coefficient is shear thickening at low shear but shear thinning at higher shear. Next, an analytical and computational study is presented that sheds light on the widely studied phenomenon of cross-streamline particle migration in Poiseuille flow. Particles are found to experience a cross-stream force toward the channel center when they are freely suspended in the fluid, while they experience a crossstream force toward the wall when they are fixed in place.

Book Description
In an area as vast and important as rheology, it is essential that the experimentalist understands the underlying theories and shortcomings of the measurement technique used, that they are aware of the likely microstructure of the fluid under study and that from this they can appreciate how the fluid and the measuring system interact with each other. This major handbook, written by an international group of experts in the range of rheological techniques, presents the state of the art in rheological measurement, and concentrates on the techniques and underlying physical principles. The second edition, fully revised and updated to include new techniques is invaluable to polymer and materials scientists, engineers and technologists, and anyone else making rheological measurements on materials whether they be polymeric, biological, slurries, food or other complex fluids.
