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.
Download or read book Environmental Effects on Polymer Matrix Composites written by C. Lee and published by . This book was released on 1997 with total page 56 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 Coupled Materials and Mechanics Analyses of Durability Tests for High Temperature Polymer Matrix Composites written by Hugh L. N. McManus and published by . This book was released on 1995 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete coupled model of the environmentally-induced degradation of composite materials, and the effect of this degradation on composite laminate behavior, is presented. Although the model is not sufficiently mature for predictive design use, it provides major insights into the mechanisms of degradation of composite materials. The model is used to study test methods frequently used to assess composite durability, including weight loss, shrinkage, and mechanical property degradation testing. It is found that even simple tests of material undergoing environmentally-induced degradation are difficult to interpret. In particular, the spatial non-uniformity of degradation converts originally simple specimens into complex structures with non-uniform chemical and mechanical states. Consideration of this complexity is vital to the full understanding of the results of such tests.
Download or read book Time Dependent and Nonlinear Effects in Polymers and Composites written by Richard Allan Schapery and published by ASTM International. This book was released on 2000 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Improved reliability in commercial and military applications requires improved understanding of and predictive models for the time- dependent and nonlinear mechanical behavior of polymeric composites. The May 1998 American Society for Testing and Materials symposium sought to fuse the efforts in this direction of specialists in polymers and composites; these 18 papers are therefore grouped under the subheadings of polymers and composites. Primary polymer topics are chemical and physical aging, nonlinear viscoelasticity, and viscoplasticity. Composites' issues include: the effect of physical aging on time-dependent behavior, multiaxial nonlinear effects, compressive behavior, nonlinear viscoelasticity and viscoplasticity, failure mechanisms, hygrothermal effects, durability, and accelerated strength testing. Schapery is affiliated with the U. of Texas at Austin, and Sun is at Purdue U. Annotation copyrighted by Book News, Inc., Portland, OR.

Download or read book Computational Modeling of Polymer Composites written by Samit Roy and published by CRC Press. This book was released on 2013-09-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Modeling of Polymer Composites: A Study of Creep and Environmental Effects details the development of polymeric materials and their use in smart materials and composite structures in aerospace and automotive industries. Based on the authors' work during the past 30 years, this book provides a strong understanding of the theories and associated finite element life-prediction models for elastic and viscoelastic response of polymers and polymer composites in aggressive environments. The subject is an interdisciplinary one where chemists, material scientists, and chemical, mechanical, and structural engineers contribute to the overall product. Books on polymer composites are usually of three types: material science, mechanics, and computational. This book combines mechanics of materials with the computational element. The authors suggest an introductory course on mechanics of materials to cover all bases. The book begins with mathematical preliminaries, equations of anisotropic elasticity, virtual work principles, and variational methods. It provides an introduction to the finite element method and finite element analysis of viscoelastic materials, and then moves on to the solvent diffusion process in polymers and polymeric composites, as well as the linear and nonlinear viscoelastic models and the implementation of finite element models of viscoelastic materials. Computational Modeling of Polymer Composites: A Study of Creep and Environmental Effects delves into both uniaxial and multiaxial cases and delayed failure before discussing the finite element analysis of the nonlinear diffusion process in polymers. It also includes non-Fickean diffusion of polymers, the coupled hygrothermal cohesive layer model for simulating debond growth in bimaterial interfaces, and the viscoelastic cohesive layer model for the prediction of interlaminar shear strength of carbon/epoxy composites. The final chapter covers a multi-scale viscoelastic cohesive layer model for predicting delamination in high temperature polymer composites. This book can be used as a reference or as a graduate course textbook on theory and/or finite element analysis of polymers and polymeric composites.
