Durability of Polymer Based Composite Systems for Structural Applications


Book Description

Advanced, high-performance composite materials are really material systems. The constituent materials interact in such a way that their collective response is more than the linear sum of the response of the constituents. This simple reality provides the technical community with a remarkable opportunity to create composite material systems which are uniquely suited to perform specific engineering tasks. At the same time, this systems aspect of composite materials is a very great challenge to the research community. In introduces complexity, nonlinearity, and scaling problems (to name a few) which require the development of new representations of material behavior, from the standpoint of mechanics, chemistry, and physics.




Durability Analysis of Structural Composite Systems


Book Description

Durability analysis can be defined as the prediction methodology of safe residual behaviour after a given life time under a complex mechanical loading history in combination with a program of environmental variations. This was, and is a central problem for the reliability of structural components whatever are the basic material systems. With composite systems, combination of different materials in interaction, an integrated material structure design becomes possible. If one of the phases is a polymer, the composite system has time dependent properties and as consequence durability analysis has to be performed taking into account the internal time factor in combination with strong influences from temperature changes and moisture diffusion. Insurance companies need information on durability and reliability in order to cover the risks, and in the event of failure lawyers have to arrive at an agreement om the responsibilites of the different actors involved in the constructiion. This book is an overview of the state of the different aspects of safe structural integrity for a given lifetime of composite structures, with special emphasis on polymer matrix composites. It is of interest for scientists and engineers involved in composites and for designers of composite structural components.




Durability of Composites for Civil Structural Applications


Book Description

Given the increasing use of fibre-reinforced polymer (FRP) composites in structural civil engineering, there is a vital need for critical information related to the overall durability and performance of these new materials under harsh and changing conditions. Durability of composites for civil and structural applications provides a thorough overview of key aspects of the durability of FRP composites for designers and practising engineers.Part one discusses general aspects of composite durability. Chapters examine mechanisms of degradation such as moisture, aqueous solutions, UV radiation, temperature, fatigue and wear. Part two then discusses ways of using FRP composites, including strengthening and rehabilitating existing structures with FRP composites, and monitoring techniques such as structural health monitoring.Durability of composites for civil and structural applications provides practising engineers, decision makers and students with a useful and fundamental guide to the use of FRP composites within civil and structural engineering. - Provides a thorough overview of key aspects of the durability of composites - Examines mechanisms of degradation such as aqueous solutions, moisture, fatigue and wear - Discusses ways of using FRP composites, including strengthening and rehabilitating existing structures

Reinforced Plastics Durability


Book Description

Reinforced plastics are becoming widely adopted for long-term structural use-in everything from buildings and bridges to boats and swimming pools. However, the lifetimes being sought are far greater than the whole history of reinforced plastics production! Reinforced Plastics Durability explores the strength and weathering characteristics which make the material ideal for numerous applications, but also alerting the user of wear and corrosion-with studies of the processes and mechanisms which cause the deterioration. Written especially for first-time users of reinforced plastics-engineers, designers, and managers alike-Reinforced Plastics Durability offers substantial introductory information with key concepts. Subsequent chapters examine the long-term threats to the integrity of reinforced plastics: outdoor weathering, solvent/water attack, high temperatures, and repetitive stress. To maximize durability, contributors to the book report on experience with specific applications over time; the possibility of repair; and use of computer techniques to predict durability. Despite mentioning many possible threats to durability, Reinforced Plastics Durability emphasizes the fact that reinforced plastics composites have performed very well in most of the application areas. Readers will be able to take advantage of that success-and to possibly take steps toward the next phase of refinements and improvements.

Recent Advances in Composite Materials


Book Description

This book contains 31 papers presented at the symposium on "Recent Advances in Composite Materials" which was organized in honor of Professor Stephanos A. Paipetis. The symposium took place at Democritus University of Thrace, in Xanthi, Greece on June 12-14, 2003. The book is a tribute to Stephanos A. Paipetis, a pioneer of composite materials, in recognition of his continuous, original diversified and outstanding contributions for half a century. The book consists of invited papers written by leading experts in the field. It contains original contributions concerning the latest developments in composite materials. It covers a wide range of subjects including experimental characterization, analytical modeling and applications of composite materials. The papers are arranged in the following six sections: General concepts, stress and failure analysis, mechanical properties, metal matrix composites, structural analysis and applications of composite materials. The first section on general concepts contains seven papers dealing with composites through the pursuit of the consilience among them, computation and mechatronic automation of multiphysics research, a theory of anisotropic scattering, wave propagation, multi-material composite wedges, a three-dimensional finite element analysis around broken fibers and an in situ assessment of the micromechanics of large scale bridging in ceramic composites.
