This book was released on 1974 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphite, boron, S-glass, and DuPont's PRD-49-III fiber reinforced composites, as well as castings of current epoxy resin systems, were evaluated to determine the effects of moisture and high humidity on their physical properties and their room- and elevated-temperature mechanical properties. All of the neat resin castings were found to absorb moisture and swell. Associated with moisture absorption is a loss in elevated-temperature tensile strength. All of the composite systems showed weight gains and thickness increases when subjected to a high-humidity environment. However, the effect of absorbed moisture on the elevated-temperature mechanical properties of composites is determined principally by fiber orientation and test method employed. Unidirectional composites may show a significant reduction of 350°F (177°C) flexural strength due to absorbed moisture, whereas a multidirectional lay-up may show only a minor loss of 350°F tensile strength after equivalent moisture absorption. Fiber-controlled composite properties are relatively unaffected by absorbed moisture whereas matrix-controlled properties are adversely affected.

Download or read book Fibrous Composites in Structural Design written by Edward M. Lenoe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 858 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Conference on Fibrous Composites in Structural Design was a successor to the First-to-Third Conferences on Fibrous Composites in Flight Vehicle Design sponsored by the Air Force (First and Second Conferences, September 1973 and May 1974) and by NASA (Third Conference, November 1975) which were aimed at focusing national attention on flight vehicle applications of a new class of fiber reinforced materials, the advanced com posites, which afforded weight savings and other advantages which had not been previously available. The Fourth Conference, held at San Diego, California, 14-17 November 1978, was the fi rst of these conferences to be jointly sponsored by the Army, Navy and Ai r Force together with NASA, as well as being the first to give attention to non-aerospace applications of fiber reinforced composites. While the design technology for aerospace applications has reached a state of relative maturity, other areas of application such as mi litary bridging, flywheel energy storage systems, ship and surface vessel components and ground vehicle components are in an early stage of development, and it was an important objective to pinpoint where careful attention to structural design was needed in such applications to achfeve maximum structural performance payoff together with a high level of reliability and attractive economics.

Available in PDF, EPUB and Kindle. Book excerpt: The papers contained herein were presented at the Second International Conference on Composite Structures (ICCS/2) held at Paisley College of Technology, Paisley, Scotland, in September 1983. The Conference was organised and sponsored by Paisley College of Technology in association with the Scottish Development Agency and the National Engineering Laboratory. It forms a natural progression from the highly successful First International Conference on Composite Structures (lCCS/l) held at Paisley in September 1981. The last few decades have seen phenomenal advances in research and of composite materials with new and exciting structural development possibilities being unearthed on an almost daily basis. Composites have been rightly heralded as space-age materials of the future. However, along with the rather specialised aerospace applications a growing awareness of the wider potential of composites is also unmistakable. The extensive composite materials research programmes of the fifties and sixties are now yielding fruit in abundance, with composites being used in virtually every area of structural engineering from transportation to pressure vessels and so on. Although significant weight savings, paramount in transportation engineering, are possible, composites have gone far beyond being simply lighter than conventional materials. They offer real structural advantages with almost unbounded potential. The ability to tailor a particular matrix material to suit prevailing environmental conditions whilst maintaining adequate reinforcement to withstand applied loading is unquestionably an attractive proposition.

Book excerpt: The ultimate tensile strengths of Thornel 300/Fiberite 1034 graphite epoxy composites were measured with material temperatures ranging from 200 K to 422 K and moisture contents from 0% (dry) to 1.5% (Fully saturated). All measurements were performed using 0 deg, 90 deg and pi/4 laminates. A survey was also made of the existing data showing the effects of temperature and moisture content on the tensile strength of different composites. (Author).
Download or read book Axiomatic Design and Fabrication of Composite Structures written by Dai Gil Lee and published by Oxford University Press. This book was released on 2006 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea that materials can be designed to satisfy specific performance requirements is relatively new. With high-performance composites, however, the entire process of designing and fabricating a part can be worked out before manufacturing. The purpose of this book is to present an integrated approach to the design and manufacturing of products from advanced composites. It shows how the basic behavior of composites and their constitutive relationships can be used during the design stage, which minimizes the complexity of manufacturing composite parts and reduces the repetitive "design-build-test" cycle. Designing it right the first time is going to determine the competitiveness of a company, the reliability of the part, the robustness of fabrication processes, and ultimately, the cost and development time of composite parts. Most of all, it should expand the use of advanced composite parts in fields that use composites only to a limited extent at this time. To achieve these goals, this book presents the design and fabrication of novel composite parts made for machine tools and other applications like robots and automobiles.This book is suitable as a textbook for graduate courses in the design and fabrication of composites. It will also be of interest to practicing engineers learning about composites and axiomatic design.A CD-ROM is included in every copy of the book, containing Axiomatic CLPT software. This program, developed by the authors, will assist readers in calculating material properties from the microstructure of the composite.This book is part of the Oxford Series on Advanced Manufacturing.

This book was released on 2012-12-06 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of development of composite materials is quite unique in the scientific world with simultaneous advances being made both in their usage and basic understanding. The complexity and high technology required in manufacturing structural parts with these materials as well as the need for fundamental description of their processing and property characteristics necessitates a close col laboration between industrial and academic researchers. This col laboration has become significant not only in solving specific tech nical problems, but in providing a much needed supply of scientists with training and background focused on anticipated demand for further advances in composite usage. The fact that the transportation industry with its current international character has a vital interest in composite materials for weight savings applications has provided a strong incentive for extending these developments beyond national boundaries. An excel lent example of an established international venture is the building of the new generation commercial aircraft by the Boeing Company with composite parts manufactured by Aerita1ia in Italy. Accordingly, we organized a Joint U. S. -Italy Symposium on Composite Materials in Italy which was successfully held on June 15-19, 1981, under the primary sponsorship of NSF in the U. S. A. and CNR in Italy. The strong support we also received from industrial co-sponsors, both from Italy and the U. S. A. , as well as our respective academic insti tutions gave us confidence that we were addressing a timely and important area in Science and Engineering with a unique concept.
