Designation:D3410/D3410M161Standard Test Method forCompressive Properties of Polymer Matrix CompositeMaterials with Unsupported Gage Section by ShearLoading1This standard is issued under the fixed designation D3410/D3410M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript 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.1NOTEEditorial corrections were made to the adjunct information in March 2021.1.Scope1.1 This test method determines the in-plane compressiveproperties of polymer matrix composite materials reinforced byhigh-modulus fibers.The composite material forms are limitedto continuous-fiber or discontinuous-fiber reinforced compos-ites for which the elastic properties are specially orthotropicwith respect to the test direction.This test procedure introducesthe compressive force into the specimen through shear atwedge grip interfaces.This type of force transfer differs fromthe procedure in Test Method D695 where compressive force istransmitted into the specimen by end-loading,Test MethodD6641/D6641M where compressive force is transmitted bycombined shear and end loading,and Test Method D5467/D5467M where compressive force is transmitted by subjectinga honeycomb core sandwich beam with thin skins to four-pointbending.1.2 This test method is applicable to composites made fromunidirectional tape,wet-tow placement,textile(for example,fabric),short fibers,or similar product forms.Some productforms may require deviations from the test method.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.Within the text theinch-pounds units are shown in brackets.The values stated ineach system are not exact equivalents;therefore,each systemmust be used independently of the other.Combining valuesfrom the two systems may result in nonconformance with thestandard.NOTE1Additional procedures for determining compressive propertiesof resin-matrix composites may be found in Test Methods D695,D5467/D5467M,and D6641/D6641M.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:2D695 Test Method for Compressive Properties of RigidPlasticsD792 Test Methods for Density and Specific Gravity(Rela-tive Density)of Plastics by DisplacementD883 Terminology Relating to PlasticsD2584 Test Method for Ignition Loss of Cured ReinforcedResinsD2734 Test Methods for Void Content of Reinforced PlasticsD3171 Test Methods for Constituent Content of CompositeMaterialsD3878 Terminology for Composite MaterialsD5229/D5229M Test Method for MoistureAbsorption Prop-erties and Equilibrium Conditioning of Polymer MatrixComposite MaterialsD5379/D5379M Test Method for Shear Properties of Com-posite Materials by the V-Notched Beam MethodD5467/D5467M Test Method for Compressive Properties ofUnidirectional Polymer Matrix Composite Materials Us-ing a Sandwich Beam1This specification 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 March 15,2016.Published March 2016.Originallyapproved in 1975.Last previous edition approved in 2008 as D3410/D3410M 03(2008).DOI:10.1520/D3410_D3410M-16E01.2For 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.1D6641/D6641M Test Method for Compressive Properties ofPolymer Matrix Composite Materials Using a CombinedLoading Compression(CLC)Test FixtureE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical TestingE83 Practice for Verification and Classif
