MIL-HDBK-17-1F Volume 1, Chapter 1 Objectives 1-1 CHAPTER 1 OBJECTIVES This handbook documents engineering methodologies for the development of standardized, statistically-based material property data for polymer matrix composite materials. Also provided are data summaries for a number of relevant composite material systems for which available data meets specific MIL-HDBK-17 requirements for publication. Additionally, supporting engineering and manufacturing technologies and common practices related to composite materials are summarized. 1.1 INTRODUCTION It is generally understood that standardized, statistically-based, 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 certifying agencies.1 This evaluation of the inherent properties of composite materials, as shown in Figure 1.1, is the focus of MIL-HDBK-17. While the source and context for much of the handbook has historically come from experience with aerospace flight-critical structures, all transportation industries (aerospace, ground, rail, and marine), whether commercial or military, as well as other applications including general industrial products, will find the handbook useful. Incorporation of additional information related to broader applications is ongoing. This handbook has been developed and is maintained as a joint effort of the US Department of Defense (DOD) and the US Federal Aviation Administration (FAA). The data contained herein, or appearing as approved items2 in the minutes of MIL-HDBK-17 coordination group meetings, while not mandatory,, are acceptable for use in the development of structural design values to the FAA and to all branches of the DOD. Note however, that methods for incorporating handbook data into structural design values for specific applications generally require additional procurement or certification agency approval. 1.2 PURPOSE The primary purpose of MIL-HDBK-17 is the standardization of engineering data development methodologies related to characterization testing, data reduction, and data reporting of properties for polymer matrix composite materials. In support of this objective MIL-HDBK-17 publishes properties on composite material systems for which data meeting specific requirements is available. In addition, MIL-HDBK-17 provides selected guidance on other technical topics related to composites, including material selection, material specification, material processing, design, analysis, quality control and repair of typical polymer matrix composite materials. Thus, MIL-HDBK-17 is published in three volumes, and serves as a source for the following: • Volume 1: Documents material characterization, data development, and methodology guidelines adaptable to a wide variety of needs, as well as specific requirements to be met by data published in the handbook. Most procuring and certifying agencies prefer, and some may require, that composite material systems used in critical applications either be characterized in accordance with Volume 1 guidelines or selected from material systems published in Volume 2. 1 An example of a procuring agency is a branch of the US Department of Defense (DOD). An example of a certifying agency is an office of the US Federal Aviation Administration (FAA). 2 Accepted as of the MIL-HDBK-17 Coordination Committee approval date

MIL-HDBK-17-1F Volume 1,Chapter 1 Objectives 1.3.1 Strength properties and allowables data Statistically-based strength property data are defined for each composite material system over a range of potential usage conditions.The intent is to provide data at the upper and lower limits of the po- tential environmental conditions for a particular material,so that application issues do not govern the me- chanical property characterizations.If data are also available at intermediate environmental conditions, they are used to more exactly define the relationship between the mechanical properties and the effect of the environment on those properties. The statistically-based strength data that are available are tabulated in Volume 2.These data are useful as a starting point for establishing structural design allowables when stress and strength analysis capabilities permit lamina level margin of safety checks.Where such cases exist,the MIL-HDBK-17 sta- tistically reduced strength data may be used in determining material design allowables.Depending on the application,some structural design allowables will have to be determined empirically by laminate,ele- ment,or higher level of testing,since MIL-HDBK-17 does not provide these data. Additional information and properties are added as they become available and are demonstrated to meet the guideline criteria.Typical property values,as well as S-values(see definitions)are included if they meet the approval of the MIL-HDBK-17 Coordination Group. When the guidelines or data requirements of MIL-HDBK-17 cannot be followed,the certifying or pro- curing government agency should be contacted to determine data requirements and other documentation which may be necessary to justify data values proposed or used by the manufacturer. 1.3.2 Volume 1:Guidelines for Characterization of Structural Materials This volume contains guidelines for determining the properties of composite material systems,their constituents,and generic structural elements,including test planning,test matrices,sampling,condition- ing.test procedure selection,data reporting,data reduction,statistical analysis,and other related topics Special attention is given to the statistical treatment and analysis of data.Volume 1 contains guidelines for general development of material characterization data as well as specific requirements 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 material system,are the focus of this handbook.Design allowable values,while often rooted in material basis values,are application dependent,and consider and include specific additional considerations that may further affect the strength or stiffness of the structure.Also,when establishing application design values there may be additional certification or procurement agency requirements that go beyond MIL-HDBK-17. 1.3.3 Volume 2:Material Properties Volume 2 contains statistically-based data meeting specific MIL-HDBK-17 population sampling and data documentation requirements,covering constituents and material systems of general interest.Data published in Volume 2 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 dis- cussed in Section 1.5).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 the MIL-HDBK-17A version of the handbook that do not meet current data sampling,test methodology,or documentation requirements,but that still are of potential interest to the industry,are also documented in an appendix to this volume. The material properties in Volume 2 are defined over a range of potential use conditions,focusing when possible,on the upper and lower material environmental limits so that application-specific environ- 1-3

The intent is to provide data at the upper and lower limits of the potential environmental conditions for a particular material, so that application issues do not govern the mechanical property characterizations. If data are also available at intermediate environmental conditions, they are used to more exactly define the relationship between the mechanical properties and the effect of the environment on those properties. The statistically-based strength data that are available are tabulated in Volume 2. These data are useful as a starting point for establishing structural design allowables when stress and strength analysis capabilities permit lamina level margin of safety checks. Where such cases exist, the MIL-HDBK-17 statistically reduced strength data may be used in determining material design allowables. Depending on the application, some structural design allowables will have to be determined empirically by laminate, element, or higher level of testing, since MIL-HDBK-17 does not provide these data. Additional information and properties are added as they become available and are demonstrated to meet the guideline criteria. Typical property values, as well as S-values (see definitions) are included if they meet the approval of the MIL-HDBK-17 Coordination Group. When the guidelines or data requirements of MIL-HDBK-17 cannot be followed, the certifying or procuring government agency should be contacted to determine data requirements and other documentation which may be necessary to justify data values proposed or used by the manufacturer. 1.3.2 Volume 1: Guidelines for Characterization of Structural Materials This volume contains guidelines for determining the properties of composite material systems, their constituents, and 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 given to the statistical treatment and analysis of data. Volume 1 contains guidelines for general development of material characterization data as well as specific requirements for publication of material data in MIL-HDBK-17. It must be emphasized that this handbook differentiates between material basis values (material allowables) and design allowable values. Material basis values, being an intrinsic property of a composite material system, are the focus of this handbook. Design allowable values, while often rooted in material basis values, are application dependent, and consider and include specific additional considerations that may further affect the strength or stiffness of the structure. Also, when establishing application design values there may be additional certification or procurement agency requirements that go beyond MIL-HDBK-17. 1.3.3 Volume 2: Material Properties Volume 2 contains statistically-based data meeting specific MIL-HDBK-17 population sampling and data documentation requirements, covering constituents and material systems of general interest. Data published in Volume 2 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 1.5). 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 the MIL-HDBK-17A version of the handbook that do not meet current data sampling, test methodology, or documentation requirements, but that still are of potential interest to the industry, are also documented in an appendix to this volume. The material properties in Volume 2 are defined over a range of potential use conditions, focusing, when possible, on the upper and lower material environmental limits so that application-specific environ-

While the process of establishing structural design values for specific applications can begin with the data contained in Volume 2,most applications require collection of additional data,especially if there are requirements for data from the laminate or higher structural complexity levels (structural complexity level is discussed in 2.1.2.1).Also,the ability to manufacture material equivalent to that from which the data in Volume 2 were obtained typically must be proven to the procuring or certifying agency,which usually in- volves limited testing and data comparison.General guidelines for such material/process equivalence evaluation are presented in Volume 1:however,many of the details of such an evaluation remain at the discretion of the procuring or certifying agency. 1.3.4 Volume 3:Materials Usage,Design,and Analysis Guidelines Volume 3 provides methodologies and lessons learned for the design,manufacture,analysis,and supportability of composite structures,and for utilization of the material data provided in Volume 2 consis- tent with the guidance provided in Volume 1.Topics discussed in Volume 3 include materials and proc- essing,quality control,design and analysis,joints,reliability,thick composites,and supportability. 1.4 USE OF THE DOCUMENT AND LIMITATIONS 1.4.1 Roadmaps for use of Volumes 1-3 The following pages provide summary roadmaps that are intended to be brief guides to relevant sec- tions of this document pertaining to the following topics.The roadmaps are brief guides to the handbook, and while they indicate a general process flow for the topics,they do not show the detailed process flows. interactions and loops that are required in the actual process implementation.In some cases there are overlaps between the various roadmaps.Some minor sections have not been included;for these the reader is referred to the complete handbook table of contents.
