Book Synopsis Environmental Degradation of Industrial Composites by : Celine A Mahieux
Download or read book Environmental Degradation of Industrial Composites written by Celine A Mahieux and published by Elsevier. This book was released on 2005-12-14 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 accuracyThis 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
Book Synopsis Environmental Effects on Polymer-Matrix Composites by :
Download or read book Environmental Effects on Polymer-Matrix Composites written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of environmental factors can influence the performance of advanced polymers and composites. In particular, exposure to a combination of moisture and elevated temperature can significantly alter properties. The extent of chemical and physical changes is a function of exposure time and the temperature and humidity of the environment. This work discusses the effects of chemical and physical aging of AFR700B, a high-temperature addition polyimide resin. Neat resin samples were isothermally aged for 500 and 1000 hours at 250 deg C in dry air, humid air, and dry nitrogen. Changes in the dynamic mechanical properties and weight of the resin samples after these different exposures are discussed. An accelerated aging process was developed to facilitate the study of hydrolytic degradation. The effect of degradation on the Tg, weight, and mechanical behavior is discussed. The use of a silicon-nitride moisture barrier proved ineffective.

Download or read book Failure Mechanisms in Polymer Matrix Composites written by Paul Robinson and published by Woodhead Publishing Limited. This book was released on 2016-06 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer matrix composites are replacing materials such as metals in industries such as aerospace, automotive and civil engineering. As composites are relatively new materials, more information on the potential risk of failure is needed to ensure safe design. This book focuses on three main types of failure: impact damage, delamination and fatigue. Chapters in Parts 1-4 describe the main types of failure mechanism and discuss testing methods for predicting failure in composites. Chapters in Parts 5 and 6 discuss typical kinds of in-service failure and their implications for industry.
Book Synopsis Going to Extremes by : National Research Council
Download or read book Going to Extremes written by National Research Council and published by National Academies Press. This book was released on 2005-10-22 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Marine Environmental Effects on Polymer Matrix Composites by : LA. Carlsson
Download or read book Marine Environmental Effects on Polymer Matrix Composites written by LA. Carlsson and published by . This book was released on 1995 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degradation of polymeric matrix composite materials in marine environments has been experimentally investigated. Carbon/epoxy, carbon/bismaleimeide-epoxy, glass/epoxy and glass/PPS, and neat PPS were examined. The environments considered were distilled water and natural seawater at room temperature and 35°C. Water absorption was monitored during seven months of immersion. Several specimen geometries were investigated which allowed determination of longitudinal and transverse diffusivities. Degradation of mechanical performance due to water absorption was examined through transverse tension testing of dry and wet composites. The transverse modulus of the thermoset composites remained virtually unaffected by water absorption, while the modulus of glass/PPS dropped substantially, apparently due to extensive fiber/matrix debonding induced by water absorption. Transverse tensile strength was drastically reduced after water absorption for all composites. The composites degraded similarly in distilled water and seawater. Inspection of the fracture surfaces of dry and wet composites in a scanning electron microscope indicated that fiber/matrix adhesion was adequate in the dry composites, while in the wet composites numerous bare debonded fibers were observed, which substantiates that the reduction in transverse strength is largely due to fiber/matrix interfacial degradation.

Book Synopsis Study of Space Environmental Effects on Polymer Matrix Composite Materials by : R. C. Tennyson
Download or read book Study of Space Environmental Effects on Polymer Matrix Composite Materials written by R. C. Tennyson and published by . This book was released on 1982 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report summarizes the research results on space environmental effects including vacuum, temperature, and radiation on the coefficient of thermal expansion (CTE), stiffness, creep, and material damping in graphite/epoxy and Kevlar/epoxy composite laminates, obtained over the period 1 November 1981 to 31 October 1982 under AFOSR-78-3694 funding. This submission is intended to supplement the previous three annual reports and thus should be read in context with those documents. The main accomplishments in this 12 month period have been in the study of UV and electron radiation effects on composites in a thermo-vacuum environment, and the development and experimental validation of viscoelastic and laminate damping models for composites. In hard vacuum, matrix stiffness increases over a wide temperature range, matrix creep compliance and material damping decrease, and CTE changes depending on laminate configuration. Combined UV radiation in hard vacuum along with some Beta-radiation testing produced only minor variation in matrix stiffness, creep compliance, and CTE iwth exposures up to 300 equivalent solar days. Thermal-vacuum cycling resulted in matrix stiffness and tensile strength reduction, and CTE drift. Laminate models used were quite accurate in predicting CTE, damping, creep, and strength of arbitrary laminate configurations based on material property data obtained under different environmental conditions.
