Since the inherent properties of materi
14、als 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 certifying agencies. (A
15、n example of procuring agency is a branch of the U.S. Department of Defense, and an example of certifying agency is an office of the U.S. Federal Aviation Administration.) This evaluation of the inherent properties of ceramic matrix composite materials is the focus of MIL-HDBK-17 Volume 5. Material
16、properties are continuously improving and those reported in this handbook are typical properties at the time of press. 1.1.1 Objectives of Ceramic Matrix Composite (CMC) Working Groups Overall Vision for CMC: MIL-HDBK-17 is the primary and authoritative source for characterization and statistically-
17、based property and performance data of current and emerging advanced ceramic matrix composites. It re-flects the best available data and methodologies for characterization, testing, analysis and design, and includes data development and usage guidelines in support of design methodologies for compo-n
18、ents. Goals: A framework for the successful use of CMCs. Guidance to industry for the collection of statistically meaningful critical data that designers need to utilize CMCs. Appropriate prioritization of property requirements and broadly accepted testing procedures - includ-ing a consideration of
19、the designation of the precision level, based on the requirements from the de-sign community. Guidelines and recommendations for the characterization, processing, testing, design, and utilization of ceramic matrix composite materials and structures.

Goals: To define the essential elements of information on composition, structure, and processing of CMCs necessary to design, select, fabricate, and utilize
28、 CMC structures. To specify the methods and procedures to be used in the characterization of ceramic matrix compos-ites and their constituents. To provide a comprehensive overview of ceramic matrix composite technology, outlining the history, applications, benefits, ceramic composite systems, method
29、s of fabrication, quality control, and sup-portability. Objectives: Define the materials and processing data elements and formats for the CMC data sheets. Define materials and processing data package requirements, in terms of nomenclatures, methods, formats and priorities. Provide detailed guidance

Prepare the Materials, Processing, it is not applicable to the Federal Aviation Administration (FAA) or other
31、 government agencies. The four parts of MIL-HDBK-17, Volume 5, serve as a general Reference source for technical infor-mation on ceramic matrix composites, including: 1.3.1 Part A: Introduction and Guidelines This part contains guidelines for determining the properties of composite material systems,
32、 their con-stituents, and generic structural elements, including test planning, test matrices, sampling, conditioning, test procedure selection, data reporting, data reduction, statistical analysis, and other related topics. Part A contains guidelines for general development of material characteriza
33、tion data as well as specific re-quirements for publication of material data in MIL-HDBK-17. It must be emphasized that this handbook differentiates between material basis values (material al-lowables) and design allowable values. Material basis values, being an intrinsic property of a composite mat
34、erial system, are the focus of this handbook. Design allowable values, while often rooted in material basis values, are application dependent, and include specific additional considerations that may further affect the strength or stiffness of the structure. Also, when establishing application design
35、 values there may be additional certification or procurement agency requirements that go beyond MIL-HDBK-17. 1.3.2 Part B: Design Supportability Part B provides methodologies and lessons learned for the design, manufacture, analysis, and sup-portability of composite structures, and for utilization o
36、f the material data provided in Part D consistent with the guidance provided in Part A. Topics discussed in Part B include materials and processing, quality control, design and analysis, joints, reliability, thick composites, and supportability. 1.3.3 Part C: Testing Part C addresses issues related
37、to test methods and requirements for submission of data to MIL-17. 1.3.4 Part D: Data Requirements and Data Sets Part D contains statistically-based data meeting specific MIL-HDBK-17 population sampling and data documentation requirements, covering constituents and material systems of general intere
38、st. Data pub-lished in Part D are under the jurisdiction of the Data Review Working Group and are approved by the overall Coordination Group (The MIL-HDBK-17 Coordination Group and Working Groups are discussed in Section 1.1). New material systems will be included and additional material data for ex
39、isting systems will be added as approved data becomes available. The material properties in Part D are defined over a range of potential use conditions, focusing, when possible, on the upper and lower material environmental limits so that application-specific environments do not limit use of the dat
40、a. Special attention is given to the statistical treatment and analysis of data. Data at intermediate environmental conditions, when available, provide additional definition of the relation between material response and environment. While the process of establishing structural design values for spec
41、ific applications can begin with the data contained in Part D, most applications require collection of additional data, especially if there are re-quirements for data from the laminate or higher structural complexity levels. Also, the ability to manufac-ture material equivalent to that from which th
42、e data in Part D were obtained typically must be proven to the procuring or certifying agency, which usually involves limited testing and data comparison.

43、tion and Guidelines 7 guidelines for such material/process equivalence evaluation are presented in Part A; however, many of the details of such an evaluation remain at the discretion of the procuring or certifying agency. 1.4 USE OF THE DOCUMENT AND LIMITATIONS 1.4.1 Source of information The inform
44、ation contained in MIL-HDBK-17 is obtained from materials producers and fabricators, the aerospace industry, reports on government-sponsored research, open literature, direct contacts with re-searchers, and from participants in MIL-HDBK-17 coordination activities. All information published in this d
45、ocument has been coordinated and reviewed by representatives from industry, the US Army, the US Air Force, US Navy, the US Federal Aviation Administration, the Department of Energy, and NASA. Every effort has been made to reflect the most up-to-date information on the use of composite materials, wit
46、h particular emphasis on use of composites in structures. The handbook is continually reviewed and re-vised to keep current with the state-of-the-art in order to ensure completeness and accuracy. 1.4.2 Use of data and guidelines in applications All data contained herein are based on small-scale test
47、 specimens, predominantly loaded quasi-statically and uniaxially, for specific environmental conditions.1It is the users responsibility to determine if handbook data are appropriate for a given application and to translate or scale the data as necessary for use: in a multi-directional laminate, on a
48、 structure of different characteristic size and geometry, under a multi-directional stress state, when exposed to a different environment, and/or when subjected to non-static loading. Further discussions of these and other issues are provided in Part D. Specific uses of handbook data are beyond the
49、scope and responsibility of MIL-HDBK-17, and applicability and interpretation of specific pro-visions of this handbook may require approval by an appropriate procurement or certification agency. 1.4.3 Strength properties and allowables terminology The handbook intent is to provide guidelines for generating material property data, including statisti-cally-based strength data at environmental extremes that bracket most intermediate application-specific environments. The philosophy is to avoid havi
