Designation:D355217Standard Test Method forTensile Properties of Fiber Reinforced Metal MatrixComposites1This standard is issued under the fixed designation D3552;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers the determination of the tensileproperties of metal matrix composites reinforced by continuousand discontinuous high-modulus fibers.Nontraditional metalmatrix composites as stated in 1.1.6 also are covered in this testmethod.This test method applies to specimens loaded in auniaxial manner tested in laboratory air at either room tem-perature or elevated temperatures.The types of metal matrixcomposites covered are:1.1.1 UnidirectionalAny fiber-reinforced composite withall fibers aligned in a single direction.Continuous or discon-tinuous reinforcing fibers,longitudinal and transverse proper-ties.1.1.2 0/90 Balanced CrossplyA laminate composed ofonly 0 and 90 plies.This is not necessarily symmetric,continuous,or discontinuous reinforcing fibers.1.1.3 Angleply LaminateAny balanced laminate consist-ing of 6 theta plies where theta is an acute angle with respectto a reference direction.Continuous reinforcing fibers without0 reinforcing fibers(that is,(645)ns,(630)ns,and so forth).1.1.4 Quasi-Isotropic LaminateAbalanced and symmetriclaminate for which a constitutive property of interest,at a givenpoint,displays isotropic behavior in the plane of the laminate.Continuous reinforcing fibers with 0 reinforcing fibers(that is,(0/645/90)s,(0/630)s,and so forth).1.1.5 Unoriented and Random Discontinuous Fibers.1.1.6 Directionally Solidified Eutectic Composites.1.2 The technical content of this standard has been stablesince 1996 without significant objection from its stakeholders.As there is limited technical support for the maintenance of thisstandard,changes since that date have been limited to itemsrequired to retain consistency with other ASTM D30 Commit-tee standards.The standard therefore should not be consideredto include any significant changes in approach and practicesince 1996.Future maintenance of the standard will only be inresponse to specific requests and performed only as technicalsupport allows.1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are provided forinformation purposes only.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D3878 Terminology for Composite MaterialsE4 Practices for Force Verification of Testing MachinesE8 Test Methods for Tension Testing of Metallic MaterialsE83 Practice for Verification and Classification of Exten-someter SystemsE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE456 Terminology Relating to Quality and StatisticsE1012 Practice for Verification of Testing Frame and Speci-men Alignment Under Tensile and Compressive AxialForce Application3.Terminology3.1 DefinitionsTerminology D3878 defines terms relatingto high-modulus fibers and their composites.Terminology E6defines terms relating to mechanical testing.Terminology E4561This test method is under the jurisdiction of ASTM Committee D30 onComposite Materials and is the direct responsibility of Subcommittee D30.04 onLamina and Laminate Test Methods.Current edition approved Oct.15,2017.Published October 2017.Originallyapproved in 1977.Last previous edition approved in 2012 as D3552 12.DOI:10.1520/D3552-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 and Practice E177 define terms relatin
