Book excerpt: 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 Synopsis Nondestructive Evaluation of Materials by Infrared Thermography by : Xavier P.V. Maldague

Download or read book Nondestructive Evaluation of Materials by Infrared Thermography written by Xavier P.V. Maldague. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Infrared Thermography and Thermoelastic Stress Analysis of Composite Materials and Structural Systems by : Shane Miguel Johnson

Download or read book Infrared Thermography and Thermoelastic Stress Analysis of Composite Materials and Structural Systems written by Shane Miguel Johnson. This book was released on 2006. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Infrared Thermography Recent Advances and Future Trends by : Carosena Meola

Download or read book Infrared Thermography Recent Advances and Future Trends written by Carosena Meola. This book was released on 2012-08-03. Available in PDF, EPUB and Kindle. Book excerpt: 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.
