Thanks to their low density and tailored properties, polymer matrix composites are attractive candidates for a large number of industrial applications ranging from aerospace to transportation and energy. However, the behaviour of polymer-based materials is strongly affected by a number of environmental factors. Environmental Degradation in Industrial Composites provides vital information on the effects of environmental factors such as temperature, liquid and gas exposure, electrical fields and radiations, and how micro- and micromechanical calculations during design and manufacture must take these effects into account. The book concludes with reviews on standard and specific testing methods for the various environmental factors and their combinations, helping mechanical/materials engineers and specifiers to predict possible changes due to environmental conditions. Each chapter is supplemented by industrial case studies to help in the understanding of degradation of composites in real life situations. This book will help you to... * Understand how environmental factors lead to degradation effects in polymer matrix composite structures * Build these factors into calculations when predicting the part performance and lifetime of structures * Compare real-life situations from case studies with your predicted results * Predict probable composite behaviour with greater accuracy This book will help you to... * Understand how environmental factors lead to degradation effects in polymer matrix composite structures * Build these factors into calculations when predicting the part performance and lifetime of structures * Compare real-life situations from case studies with your predicted results * Predict probable composite behaviour with greater accuracy

The well documented increase in the use of high performance composites as structural materials in aerospace components is continuously raising the demands in terms of dynamic performance, structural integrity, reliable life monitoring systems and adaptive actuating abilities. Current technologies address the above issues separately; material property tailoring and custom design practices aim to the enhancement of dynamic and damage tolerance characteristics, whereas life monitoring and actuation is performed with embedded sensors that may be detrimental to the structural integrity of the component. This publication explores the unique properties of carbon nanotubes (CNT) as an additive in the matrix of Fibre Reinforced Plastics (FRP), for producing structural composites with improved mechanical performance as well as sensing/actuating capabilities. The successful combination of the CNT properties and existing sensing actuating technologies leads to the realization of a multifunctional FRP structure. The current volume presents the state of the art research in this field. The contributions cover all the aspects of the novel composite systems, i.e. modeling from nano to macro scale, enhancement of structural efficiency, dispersion and manufacturing, integral health monitoring abilities, Raman monitoring, as well as the capabilities that ordered carbon nanotube arrays offer in terms of sensing and/or actuating in aerospace composites.

Polymer matrix composites are increasingly replacing traditional materials, such as metals, for applications in the aerospace, automotive and marine industries. Because of the relatively recent development of these composites there is extensive on-going research to improve the understanding and modelling of their behaviour – particularly their failure processes. As a consequence there is a strong demand among design engineers for the latest information on this behaviour in order to fully exploit the potential of these materials for a wide range of weight-sensitive applications. Failure mechanisms in polymer matrix composites explores the main types of composite failure and examines their implications in specific applications. Part one discusses various failure mechanisms, including a consideration of manufacturing defects and addressing a variety of loading forms such as impact and the implications for structural integrity. This part also reviews testing techniques and modelling methods for predicting potential failure in composites. Part two investigates the effects of polymer-matrix composite failure in a range of industries including aerospace, automotive and other transport, defence, marine and off-shore applications. Recycling issues and environmental factors affecting the use of composite materials are also considered. With its distinguished editors and international team of expert contributors Failure mechanisms in polymer matrix composites is a valuable reference for designers, scientists and research and development managers working in the increasing range of industries in which composite materials are extensively used. The book will also be a useful guide for academics studying in the composites field. Discusses various failure mechanisms, including manufacturing defects Reviews testing techniques and modelling methods for predicting potential failure Investigates failure in aerospace, automotive, defence, marine and off-shore applications

Advanced polymer matrix composites (PMC) have many advantages such as light weight and high specific strength that make them useful for many aerospace applications. Enormous uncertainty exists, however, in predicting long-term changes in properties of PMCs under extreme environmental conditions, which has limited their use. To help address this issue, the Department of Defense requested a study from the NRC to identify the barriers and limitations to the use of PMCs in extreme environments. The study was to focus on issues surrounding methodologies for predicting long-term performance. This report provides a review of the challenges facing application of PMCs in extreme environments, the current understanding of PMC properties and behavior, an analysis of the importance of data in developing effective models, and recommendations for improving long-term predictive methodologies.

The vast majority of plastic products are made from petroleum-based synthetic polymers that do not degrade in a landfill or in a compost-like environment. Therefore, the disposal of these products poses a serious environmental problem. An environmentally-conscious alternative is to design/synthesize polymers that are biodegradable. Biodegradable polymers for industrial applications introduces the subject in part one by outlining the classification and development of biodegradable polymers with individual chapters on polyhydroxyalkanoates, polyesteramides and thermoplastic starch biodegradable polymers and others. The second part explores the materials available for the production of biodegradable polymers. Polymers derived from sugars, natural fibres, renewable forest resources, poly(lactic acid) and protein-nanoparticle composites will be looked at in detail in this section. Part three looks at the properties and mechanisms of degradation, prefacing the subject with a chapter on current standards. The final part explores opportunities for industrial applications, with chapters on packing, agriculture and biodegradable polycaprolactone foams in supercritical carbon dioxide. Biodegradable polymers for industrial applications explores the fundamental concepts concerning the development of biodegradable polymers, degradable polymers from sustainable sources, degradation and properties and industrial applications. It is an authoritative book that will be invaluable for academics, researchers and policy makers in the industry.
