Book Description
Infrared Thermography in the Evaluation of Aerospace Composite Materials: Infrared Thermography to Composites provides an update on infrared thermography, a fast and reliable method for non-destructive evaluation of composite materials used in the aerospace field. The book describes composites and the main problems that can arise both during manufacturing and when in service, and then covers different thermographic non-destructive testing and evaluation techniques, including pulse thermography, lock-in thermography, and pulse phase. Each technique includes key examples and relevant references, with sections devoted to the usefulness of an infrared imaging device to monitor the behavior of a material under load, such as impact and bending. The book also includes discussions on standards, personnel certification, and training. Provides a comprehensive look at the use of infrared thermography in the materials science field Describes thermographic techniques of non-destructive testing in an easy way, and with links to aeronautical standards Addresses different types of composite problems and how they can be helped through the use of infrared thermography Includes key examples and relevant references, with sections devoted to the usefulness of an infrared imaging device to monitor the behavior of a material under load

Book Description
With national trade barriers falling, causing the expansion of the com petitive global market, the question of quality control has become an essential issue for the 1990s. The time where the promise was to replace a product if it does not work seems to have passed; what is more impor tant now is not so much a reduction in what is going wrong but an increase of what is going right the first time (Feigenbaum 1990). This new trend is sometimes referred to as total quality. Among the many advantages ofthis zero-defect manufacturing policy, we can enumerate (Laurin 1990): superior marketability of wholly de pendable products, enormous gain in productivity, elimination of waste ful cost in replacing poor quality work and retrofitting rejected products from the field. Although total quality is a relatively new and attractive concept for mass products such as cars, consumer electronics and per sonal computers, in many fields, mainly aerospace and military, it has been the rule for years because of security reasons.

Book Description
This study expands on the work of ElHajjar and HajAli (2003) on a quantitative thermoelastic strain analysis method for composite materials. Computational models for various prepreg and thicksection composites are validated with experiments using this quantitative strain analysis method. This study provides this thermomechanical calibrations for prepreg S2glass/epoxy, Carbon/epoxy, and pultruded Eglass/polyester. A research collaboration with the Institute of Paper Science and Technology (IPST) focused on infrared thermography for defect detection in wood and fibrous materials and structural systems. This study provides some detailed information on various testing setups for fiber and corrugated board systems to analyze anomalies and manufacturing defects. Quantitative infrared thermography is suggested as a preferred method for assessing the bond quality in corrugated paper systems. Methods for tracking fullfield thermal data during fatigue have been developed for FRP composites. The temperature changes on the surface of an FRP composite caused by damage during fatigue are tracked and thermoelastic stress analysis (TSA) technique is developed to relate the surface deformation to the IR emission. Infrared thermography is developed for fatigue damage detection in FRP composites with stochastic methods for analyzing this fullfield data. Future damage detection techniques in aging aircraft will require quantitative and noncontact nondestructive evaluation (NDE) methods especially for composite components. Infrared (IR) thermograpy techniques are qualitatively used to assess and indirectly infer the durability of structural systems. A research collaboration with Lockheed Martin for nondestructive evaluation of composite lap shear joints led to a development of thermoelastic stress analysis techniques for evaluation aerospace structures. Infrared thermography is used to investigate failure initiation and progression in composite lap shear joints.

Book Description
Infrared thermography (IRT) is a non-contact, non-invasive methodology which allows for detection of thermal energy that is radiated from objects in the infrared band of the electromagnetic spectrum, for conversion of such energy into a visible image (such as a surface temperature map). This feature represents a great potential to be exploited in a vast variety of fields from aerospace to civil engineering, to medicine, to agriculture, etc. However, IRT is still not adequately enclosed in industrial instrumentation and there are still potential users who might benefit from the use of such a technique and who are not aware of their existence. This e-book conveys information about basic IRT theory, infrared detectors, signal digitalization and applications of infrared thermography in many fields such as medicine, foodstuff conservation, fluid-dynamics, architecture, anthropology, condition monitoring, non destructive testing and evaluation of materials and structures. The volume promotes an exchange of information between the academic world and industry, and shares methodologies which were independently developed and applied in specific disciplines.

Book Description
This book, consisting of 21 articles, including three review papers, written by research groups of experts in the field, considers recent research on reinforced polymer composites. Most of them relate to the fiber-reinforced polymer composites, which are a real hot topic in the field. Depending on the reinforcing fiber nature, such composites are divided into synthetic and natural fiber-reinforced ones. Synthetic fibers, such as carbon, glass, or basalt, provide more stiffness, while natural fibers, such as jute, flax, bamboo, kenaf, and others, are inexpensive and biodegradable, making them environmentally friendly. To acquire the benefits of design flexibility and recycling possibilities, natural reinforcers can be hybridized with small amounts of synthetic fibers to make them more desirable for technical applications. Elaborated composites have great potential as structural materials in automotive, marine and aerospace application, as fire resistant concrete, in bridge systems, as mechanical gear pair, as biomedical materials for dentistry and orthopedic application and tissue engineering, as well as functional materials such as proton-exchange membranes, biodegradable superabsorbent resins and polymer electrolytes.

Book Description
Fused Deposition Modeling of Composite Materials is dedicated to the field of 3D-printing of composite materials using a popular technique called Fused Deposition Modeling (FDM), the world’s most popular 3D printing method. But this method is currently limited to printing basic polymers and only a handful of primitive composite materials. Many future industries, such as Space, Biomed, Construction and Defense are waiting for the ability to 3D print composites and new functional materials with complex shapes and features so they can add unique and customizable features to their parts, including biocompatibility, radiation shielding, high-strength, rapid cooling, flexibility and shape-memory. The book's authors take the reader through the basics of what the FDM technique is all about and describe the advantages and new opportunities arising from 3D printing innovative materials, which include polymer-matrix composites and fully inorganic parts. They then review and discuss methods for making the different types of composite feedstock filaments needed to 3D print such materials by FDM. Finally, sections discuss the challenges that should be considered in making filaments and parts and how to go about solving them. Covers the 3D printing of composite materials Includes comprehensive coverage of this new and emerging technology Written in a clear, practical and informative style, with numerous illustrations Contains case study examples taken from cutting-edge scientific literature
