Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 presents the fundamental principles related to polymer processign operations including the processing of thermoplastic polymers and thermosets. The objective of this volume is not to provide recipies that necessarily guarantee better product quality. Rather, emphasis is placed on presenting a fundamental approach to effectively analyze processing operations. The specific polymer processing operations for thermoplastics include plasticating single-screw extrusion, morphology evolution during compounding of polymer blends, compatibilization of immiscible polymer blends, wire coating extrusion, fiber spinning, tubular film blowing, coextrusion, and thermoplastic foam extrusion. The specific polymer processing operations for thermosets include reaction injection molding, pultrusion of fiber-reinforced thermosets, and compression molding of thermoset composites.

Download or read book Theoretical Studies of Hollow Fiber Spinning written by Yang Su and published by . This book was released on 2007 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical analysis of the hollow fiber spinning process is presented. The full two-dimensional conservation equations are solved for both the bore and clad fluids. Simulation results provide steady-state axial and radial profiles of velocity, temperature, and concentration in the spinneret and draw zone. Transient simulations allow the study of hollow fiber spinning instabilities as well. Isothermal simulations reveal that a recirculation region may exist in the bore fluid under certain operating conditions. For a given die geometry, the presence and size of the recirculation region is dependent on the bore-to-clad flow rate ratio and bore-to-clad viscosity ratio. The appearance of the recirculation region leads to a more rapid decrease of fiber radii after die swell and outer radii predictions are in better agreement with experimental observations than predictions from the one-dimensional thin filament analysis. The predicted two-dimensional temperature profiles for a typical solution hollow fiber spinning process are in good agreement with the one-dimensional approximation. However, significant differences exist between the predicted one- and two-dimensional concentration profiles, especially with a concentration dependent mutual diffusion coefficient. An improved one-dimensional analysis is presented based upon the superposition principle that virtually eliminates the differences between the 1D and 2D results. Transient simulations confirm the conclusion of previous one-dimensional linear and non-linear stability analyses. The results indicate that a critical draw ratio exists above which the spinline is unstable when subjected to a finite disturbance. The results also show that the critical draw ratio increases as Reynolds number increases in agreement with predictions for solid fiber spinning. Experimental measurements of fiber size are presented for the isothermal spinning of a hollow Newtonian filament using a silicone oil clad and air bore. For the experiments, the force exerted by gravity on the filament dominates draw down and the 1D and 2D simulations predict almost identical diameter profiles. The observed variation of OD along the spinline agrees qualitatively with the theoretical results. However, some discrepancy exists that is attributed to the effect of non-Newtonian die swell.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotube Superfiber Materials refers to different forms of macroscale materials with unique properties constructed from carbon nanotubes. These materials include nanotube arrays, ribbons, scrolls, yarn, braid, and sheets. Nanotube materials are in the early stage of development and this is the first dedicated book on the subject. Transitioning from molecules to materials is a breakthrough that will positively impact almost all industries and areas of society. Key properties of superfiber materials are high flexibility and fatigue resistance, high energy absorption, high strength, good electrical conductivity, high maximum current density, reduced skin and proximity effects, high thermal conductivity, lightweight, good field emission, piezoresistive, magnetoresistive, thermoelectric, and other properties. These properties will open up the door to dozens of applications including replacing copper wire for power conduction, EMI shielding, coax cable, carbon biofiber, bullet-proof vests, impact resistant glass, wearable antennas, biomedical microdevices, biosensors, self-sensing composites, supercapacitors, superinductors, hybrid superconductor, reinforced elastomers, nerve scaffolding, energy storage, and many others. The scope of the book covers three main areas: Part I: Processing; Part II: Properties; and Part III: Applications. Processing involves nanotube synthesis and macro scale material formation methods. Properties covers the mechanical, electrical, chemical and other properties of nanotubes and macroscale materials. Different approaches to growing high quality long nanotubes and spinning the nanotubes into yarn are explained in detail. The best ideas are collected from all around the world including commercial approaches. Applications of nanotube superfiber cover a huge field and provides a broad survey of uses. The book gives a broad overview starting from bioelectronics to carbon industrial machines. First book to explore the production and applications of macro-scale materials made from nano-scale particles Sets out the processes for producing macro-scale materials from carbon nanotubes, and describes the unique properties of these materials Potential applications for CNT fiber/yarn include replacing copper wire for power conduction, EMI shielding, coax cable, carbon biofiber, bullet-proof vests, impact resistant glass, wearable antennas, biomedical microdevices, biosensors, self-sensing composites, supercapacitors, superinductors, hybrid superconductor, reinforced elastomers, nerve scaffolding, energy storage, and many others

This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large, fast, digital computers have been widely used in engineering practice and their use has had a large impact in many fields. Polymer processing is no exception, and there is already a substantial amount of literature describing ways in which processes can be analysed, designed or controlled using the potentialities of modern computers. The emphasis given varies with the application, and most authors tend to quote the results of their calculations rather than describing in any detail the way the calculations were undertaken or the difficulties experienced in carrying them out. We aim to give here as useful and connected an account as we can of a wide class of applications, for the benefit of scientists and engineers who find themselves working on polymer processing problems and feel the need to undertake such calculations. The major application we have in mind is the simulation of the dynamics ofthe various physical phenomena which arise in a polymer process treated as a complex engineering system. This requires that the system be reasonably well represented by a limited number of relatively simple subprocesses whose connections can be clearly identified, that the domi nant physical effects relevant to each subprocess can be well defined in a suitable mathematical form and that the sets of equations and boundary conditions developed to describe the whole system can be successfully discretised and solved numerically.

This book was released on 2007 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2-D analysis of fiber spinning is presented for nylon, PET, and PLA. Radial variations in temperature and degree of crystalline transformation and microstructure for the PLA and higher speed PET examples show significant patterns in the skin and core regions of the fiber that reflect the interplay between FEC and thermal-induced crystallization (TIC). Insight is gained into the relationship of TIC and FEC in determining radial birefringence profiles. Finally, a linearized sensitivity and stability analysis of fiber spinning of semi-crystalline polymers has been carried out for both low- and high-speed spinning conditions to investigate the relative roles of flow-enhanced crystallization (FEC) and thermal-induced crystallization (TIC) on the process dynamics.
