Available in PDF, EPUB and Kindle. Book excerpt: Discontinuous fiber-reinforced polymers play a significant role in the automotive industry due to their lightweight properties and excellent mechanical performance with lower manufacturing costs. Since there are many unknowns regarding how fibers interact with the polymer matrix during polymer processing, it is crucial to understand how fiber orientation, fiber length, and fiber concentration affect the final part's properties. As few modeling techniques can accurately predict both fiber damage and fiber orientation during polymer processing, such as injection molding, a particle-level simulation is used in this study to predict the fiber motion in the polymer flow. In the particle level simulation, each fiber is represented as a chain of rods that experience hydrodynamic, interaction, and elastic effects. The simulation results were compared to simple shear flow experiments conducted in a Couette Rheometer to validate the model's approach. In addition to the particle-level simulation, a modified breakage model developed in the Polymer Engineering Center, UW-Madison, was implemented as a post-processing tool for injection molding simulation using Moldex3D to find the optimum value for predicting fiber damage in the polymer process. The model was validated with different fiber content materials as well as different part geometries and processing conditions. A new form of stress-induced fiber breakage model was proposed to allow more accurate predictions on fiber attrition in polymer processing.

Ceramic fiber properties (strength, temperature and creep resistance, for example)-along with the debonding characteristics of their coatings-determine the properties of CMCs. This report outlines the state of the art in high-temperature ceramic fibers and coatings, assesses fibers and coatings in terms of future needs, and recommends promising avenues of research. CMCs are also discussed in this report to provide a context for discussing high-temperature ceramic fibers and coatings.

Available in PDF, EPUB and Kindle. Book excerpt: The nitrides and carbides of boron and silicon are proving to be an excellent choice when selecting materials for the design of devices that are to be employed under particularly demanding environmental and thermal con- tions. The high degree of cross-linking, due to the preferred coordination numbers of the predominantly covalently bonded constituents equalling or exceeding three, lends these non-oxidic ceramics a high kinetic stability, and is regarded as the microscopic origin of their impressive thermal and mechanical durability. Thus it does not come as a surprise that the chemistry, the physical properties and the engineering of the corresponding binary, ternary, and even quaternary compounds have been the subject of intensive and sustained efforts in research and development. In the five reviews presented in the volumes 101 and 102 of "Structure and Bonding" an attempt has been made to cover both the essential and the most recent advances achieved in this particular field of materials research. The scope of the individual contributions is such as to address both graduate students, specializing in ceramic materials, and all scientists in academia or industry dealing with materials research and development. Each review provides, in its introductory part, the chemical, physical and, to some extent, historical background of the respective material, and then focuses on the most relevant and the most recent achievements.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamental concepts coupled with practical, step-by-step guidance With its emphasis on core principles, this text equips readers with the skills and knowledge to design the many processes needed to safely and successfully manufacture thermoplastic parts. The first half of the text sets forth the general theory and concepts underlying polymer processing, such as the viscoelastic response of polymeric fluids and diffusion and mass transfer. Next, the text explores specific practical aspects of polymer processing, including mixing, extrusion dies, and post-die processing. By addressing a broad range of design issues and methods, the authors demonstrate how to solve most common processing problems. This Second Edition of the highly acclaimed Polymer Processing has been thoroughly updated to reflect current polymer processing issues and practices. New areas of coverage include: Micro-injection molding to produce objects weighing a fraction of a gram, such as miniature gears and biomedical devices New chapter dedicated to the recycling of thermoplastics and the processing of renewable polymers Life-cycle assessment, a systematic method for determining whether recycling is appropriate and which form of recycling is optimal Rheology of polymers containing fibers Chapters feature problem sets, enabling readers to assess and reinforce their knowledge as they progress through the text. There are also special design problems throughout the text that reflect real-world polymer processing issues. A companion website features numerical subroutines as well as guidance for using MATLAB®, IMSL®, and Excel to solve the sample problems from the text. By providing both underlying theory and practical step-by-step guidance, Polymer Processing is recommended for students in chemical, mechanical, materials, and polymer engineering.

Available in PDF, EPUB and Kindle. Book excerpt: 30 years ago, polymer processing was considered to be a set of operations aiming at imparting a desired shape to the material, while its final properties were defined exclu sively by the molecular structure and architecture resulted from the respective synthetic approaches. These two fields of knowledge - polymer processing and polymer structure - grew closer as several scientific and technological works disclosed the microstructure and other morphological features developed by polymeric systems upon different process ing conditions. Even before the real understanding of the polymer structural details, engineers were able to make use of the effect of molecular orientation and to manufacture polymeric fi bres with enhanced properties in terms of stiffness and strength. However, it was during the 1970s that the scientific community started to relate microstructure development and the thermomechanical environment associated to different processing techniques. Ever since, very important works were done on semi crystalline, amorphous or blended polymers in order to identify and, recently, to predict the effect of the imposed shear fields and cool ing gradients on the final product properties. These efforts led to more accurate process ing methods and stimulated new engineering approaches, such as property enhancement through out-of-the-processing as well as on-line control. Modem processing technology has developed further towards the nano level, enabling impacts on the macromolecular structure.
