3、ssary to design and fabricate structural components from composite materials. Its primary purposes are a) the standardization of engineering data development methodologies related to testing, data reduction, and data reporting of property data for current and emerging composite materials, b) guidanc
4、e on material and process specifi-cations and procedures for utilization of the material data presented in the handbook, and c) methodologies for the design, analysis, certification, manufacture, and field support of composite structures. In support of these objectives, the handbook includes composi

This handbook is intended to provide these through standardization of: 1. Methods used to develop, analyze, and publish pr
28、operty data for composite materials. 2. Statistically-based, material property datasets for composite materials. 3. General procedures for designing, analyzing, testing, and supporting composite structures that uti-lize the property data published in this handbook. In many cases, this standardizatio
29、n is intended to address the requirements of regulatory agencies, while providing efficient engineering practices for developing structures that meet the needs of customer organizations. Composites is an evolving and growing technical field, and the Handbook Coordinating Committee is continuously wo
30、rking to incorporate new information and new material properties data as it becomes avail-able and is proven acceptable. While the source and context for much of this information has come from experience with aerospace applications, all industries utilizing composite materials and structures, whethe
31、r commercial or military, will find the handbook useful. This latest revision includes information related to broader applications from non-aerospace industries, and incorporation of non-aerospace data will increase as development of the handbook continues.

32、as been developed and is maintained as a joint effort of the Department of Defense and the Federal Aviation Administration, with considerable participation and input from industry, academia, and other government agencies. Although initial structural applications of composites tended to be military,
33、recent development trends have seen increasing use of these materials in commercial applications. In part because of these trends, the formal administration of the handbook passed from the Department of Defense to the Federal Aviation Administration in 2006 and the handbook title was changed from Mi
34、litary Handbook-17 to Composite Materials Handbook-17. The organization of the Coordinating Committee and the purpose of the handbook did not change. This handbook documents engineering methodologies for the development of standardized, statisti-cally-based material property data for ceramic matrix
35、composite materials. Also provided are data summar-ies for a number of relevant composite material systems for which available data meet specific CMH-17 requirements for publication. Additionally, supporting engineering and manufacturing technologies and common practices related to composite materia
36、ls are summarized. 1.2 OVERVIEW OF HANDBOOK CONTENT Composite Materials Handbook-17 is composed of a series of six volumes. Volume 1: Polymer Matrix Composites - Guidelines for Characterization of Structural Materials Volume 1 contains guidelines for determining the properties of polymer matrix comp
37、osite material sys-tems and their constituents, as well as the properties of generic structural elements, including test planning, test matrices, sampling, conditioning, test procedure selection, data reporting, data reduction, statistical analysis, and other related topics. Special attention is giv
38、en to the statistical treatment and analysis of data. CMH-17-5A Volume 5, Part A Introduction and Guidelines 2 Volume 1 contains guidelines for general development of material characterization data as well as specific requirements for publication of material data in CMH-17. Volume 2: Polymer Matrix
39、Composites - Material Properties Volume 2 contains statistically-based data for polymer matrix composites that meets specific CMH-17 population sampling and data documentation requirements, covering material systems of general interest. As of the publication of Revision G, data published in Volume 2
40、 are under the jurisdiction of the Data Review Working Group and are approved by the overall CMH-17 Coordinating Committee. New material systems will be included and additional material data for existing systems will be added as data becomes available and are approved. Selected historical data from
41、previous versions of the handbook that do not meet current data sampling, test methodology, or documentation requirements, but that still are of potential interest to industry are also included in this Volume. Volume 3: Polymer Matrix Composites - Materials Usage, Design, and Analysis Volume 3 provi
42、des methodologies and lessons learned for the design, analysis, manufacture, and field support of fiber-reinforced, polymeric-matrix composite structures. It also provides guidance on material and process specifications and procedures for utilization of the data presented in Volume 2. The infor-mati
43、on provided is consistent with the guidance provided in Volume 1, and is an extensive compilation of the current knowledge and experiences of the engineers and scientists who are active in composites from industry, government, and academia. Volume 4: Metal Matrix Composites Volume 4 publishes proper
44、ties on metal matrix composite material systems for which data meeting the specific requirements of the handbook are available. In addition, it provides selected guidance on other technical topics related to this class of composites, including material selection, material specification, pro-cessing,
45、 characterization testing, data reduction, design, analysis, quality control, and repair of typical metal matrix composite materials. Volume 5: Ceramic Matrix Composites Volume 5 publishes properties on ceramic matrix composite material systems for which data meeting the specific requirements of the
46、 handbook are available. In addition, it provides selected guidance on other technical topics related to this class of composites, including material selection, material specification, pro-cessing, characterization testing, data reduction, design, analysis, quality control, and repair of typical ce-
47、ramic matrix composite materials. Volume 6: Structural Sandwich Composites Volume 6 is an update to the cancelled Military Handbook 23, which was prepared for use in the design of structural sandwich polymer composites, primarily for flight vehicles. The information presented includes test methods,
48、material properties, design and analysis techniques, fabrication methods, quality control and inspection procedures, and repair techniques for sandwich structures in both military and commercial vehi-cles. 1.3 INTRODUCTION TO VOLUME 5 It is generally understood that standardized, statistically-based
49、, material property data are essential to an efficient engineering development process; such data are needed by material suppliers, engineering users, and system end-users alike. Since the inherent properties of materials are independent of specific applications, data development methodologies and material property data are applicable to a wide variety of industries. They also form much of the technical basis for establishment of statistically-based design values acceptable to procuring or
