Encyclopedia of Polymer Composites : Properties, Performance and Applications   Publication : [S.l.] Nova Science Pub Inc 2010 . 1245 p. , In the last several years, polymer composites have been used heavily in the construction sector, such as to repair or design buildings and bridges, strengthen structures and as stand-alone components. About 30 percent of all polymers produced each year are used in the civil engineering and building industries. In addition to construction, polymer composites are also used in transportation (moulded parts, fuel and gas tanks), aerospace (satellites and aircraft structures), marine, biomedical (dental fixtures, prosthetic devices), electronics and in recreation industries. Such properties associated with polymer composites, in addition to its performance and applications, are continually being researched. Some topics examined in this book include the durability of the base components of FRP (fiber-reinforced polymer), specifically designed for civil engineering industry. The most common environmental agents, mostly responsible for the deterioration of the materials performance are also discussed. Furthermore, the interfacial adhesion between nanotubes and polymers and the different strategies to promote adhesion are explored to help readers understand the potential and challenges faced by scientists and engineers regarding the use of carbon nanotubes as a reinforcement phase in nanocomposites. This book also reviews the state-of-the-art of syntactic foams and shape memory polymers. The underlying principle for self-heating is also analyzed. Other chapters examine the processing of polymers into antimicrobial materials using polymer/clay nanotechnology, the various methods of synthesis for polyaniline-based nanoparticle-hybrid materials, and the steps towards understanding the complex relationships between specific factors in the production of plastic composites. 27 cm.

Synergetics and fractal analysis of polymer composites filled with short fibers par Kozlov, G. V. Publication : New York Nova Science Publishers Inc 2011 . 223 p. , The interest in polymer composites study is due to an even greater degree of their application. The filling by hard disperse particulates or fibres gives to polymers a desirable properties number: increases stiffness, reduces thermal expansion coefficient, rises resistance to yield and fracture toughness and so on. Difficulties in research of structure-properties relationships for polymer composites are due to their structure complexity. So, on the elasticity modulus value besides composition a polymer-filler interaction influences. In other words, it is clear even intuitively that for the complete description of such structurally-complex objects as polymer composites it is necessary to account for three groups of factors, namely, polymeric matrix structure, filler structure and level of interaction between them. Up to now the researches of such kind were carried out within the frameworks of continuous mechanics and thermodynamic conceptions. However, these conceptions application does not allow to describe satisfactorily and all the more to predict such materials properties. As a matter of fact, an experimental data set dictates the choice of either structure physical model for macroscopic properties description. 27 cm.
