Book Synopsis Preparation of Polymer Nano-Foams by : Alexander Müller
Download or read book Preparation of Polymer Nano-Foams written by Alexander Müller and published by Cuvillier Verlag. This book was released on 2013-11-27 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current energy debate considerably affects science, economy and politics. A key aspect of this discussion is energy saving by improvement of thermal insulations for buildings. In this regard, nano insulation materials (NIMs) are the insulation materials of the future. If additionally, a pore size reduction to nanoscale results in optical transparency, completely new markets for polymer foams will arise. However, the realization of these high-potential materials is accompanied by many challenges, as for example the extremely high interfacial tension emerging during foaming processes that cause an undesired coarsening of the foam structure. To overcome these challenges, new strategies and templates have to be scientifically developed. Moreover, it is crucial to understand the foaming in detail. In this context the early state of foaming was studied by means of the principle of supercritical microemulsion expansion (POSME). The benefit of using microemulsions containing a super- or near-critical fluid as oil component is the thermodynamic stability at high pressures. This allows a fast repeatability of the expansion process at nanoscale by applying pressure cycles. In combination with a specially designed stroboscopic high pressure cell, the structural processes could be observed by time resolved small angle neutron scattering experiments. It turned out that the addition of a low molecular oil as anti aging agent results in a deceleration of foam coarsening during expansion by more than an order of magnitude. Parallel to these studies, the nanofoams by continuity inversion of dispersions (NF-CID) principle was utilized for the preparation of nanoporous polymeric materials. The significant innovation of the NF-CID principle is the generation of an extremely high number density of propellant pools by a continuity inversion of a CO2-soaked colloidal crystal, i.e. the formerly discrete polymer nanoparticles convert into a homogeneous matrix with nanodisperse fluid inclusions, if the temperature is raised above the glass transition of the respective polymer. Expanding those templates by applying a specific set of parameters led to polymethylmethacrylate and polystyrene nanoporous materials that feature pore sizes smaller than 100 nm.

Book Synopsis Axiomatic Design and Fabrication of Composite Structures by : Dai Gil Lee
Download or read book Axiomatic Design and Fabrication of Composite Structures written by Dai Gil Lee and published by Oxford University Press. This book was released on 2006 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea that materials can be designed to satisfy specific performance requirements is relatively new. With high-performance composites, however, the entire process of designing and fabricating a part can be worked out before manufacturing. The purpose of this book is to present an integrated approach to the design and manufacturing of products from advanced composites. It shows how the basic behavior of composites and their constitutive relationships can be used during the design stage, which minimizes the complexity of manufacturing composite parts and reduces the repetitive "design-build-test" cycle. Designing it right the first time is going to determine the competitiveness of a company, the reliability of the part, the robustness of fabrication processes, and ultimately, the cost and development time of composite parts. Most of all, it should expand the use of advanced composite parts in fields that use composites only to a limited extent at this time. To achieve these goals, this book presents the design and fabrication of novel composite parts made for machine tools and other applications like robots and automobiles.This book is suitable as a textbook for graduate courses in the design and fabrication of composites. It will also be of interest to practicing engineers learning about composites and axiomatic design.A CD-ROM is included in every copy of the book, containing Axiomatic CLPT software. This program, developed by the authors, will assist readers in calculating material properties from the microstructure of the composite.This book is part of the Oxford Series on Advanced Manufacturing.

Book Synopsis Developments in Plastics Technology—4 by : A. Whelan
Download or read book Developments in Plastics Technology—4 written by A. Whelan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the sheer size and scope of the plastics industry, the title Developments in Plastics Technology now covers an incredibly wide range of subjects or topics. No single volume can survey the whole field in any depth and what follows is, therefore, a series of chapters on selected topics. The topics were selected by us, the editors, because of their immediate relevance to the plastics industry. When one considers the advancements of the plastics processing machinery (in terms of its speed of operation and conciseness of control), it was felt that several chapters should be included which related to the types of control systems used and the correct usage of hydraulics. The importance of using cellular, rubber-modified and engineering-type plastics has had a major impact on the plastics industry and therefore a chapter on each of these subjects has been included. The two remaining chapters are on the characterisation and behaviour of polymer structures, both subjects again being of current academic or industrial interest. Each of the contributions was written by a specialist in that field and to them all, we, the editors, extend our heartfelt thanks, as writing a contribution for a book such as this, while doing a full-time job, is no easy task.
