Designation:D5467/D5467M97(Reapproved 2017)Standard Test Method forCompressive Properties of Unidirectional Polymer MatrixComposite Materials Using a Sandwich Beam1This standard is issued under the fixed designation D5467/D5467M;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.1.Scope1.1 This test method covers the in-plane compressive prop-erties of polymer matrix composite materials reinforced byhigh-modulus fibers in a sandwich beam configuration.Thecomposite material forms are limited to continuous-fiber com-posites of unidirectional orientation.This test procedure intro-duces compressive load into a thin skin bonded to a thickhoneycomb core with the compressive load transmitted into thesample by subjecting the beam to four-point bending.1.2 This procedure is applicable primarily to laminatesmade from prepreg or similar product forms.Other 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.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3.1 Within the text the inch-pound units are shown inbrackets.NOTE1Additional procedures for determining compressive propertiesof polymer matrix composites may be found in Test Methods D3410/D3410M and D695.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.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 CompositeMaterialsD3410/D3410M Test Method for Compressive Properties ofPolymer Matrix Composite Materials with UnsupportedGage Section by Shear LoadingD3878 Terminology for Composite MaterialsD5229/D5229M Test Method for MoistureAbsorption Prop-erties and Equilibrium Conditioning of Polymer MatrixComposite MaterialsE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical TestingE111 Test Method for Youngs Modulus,Tangent Modulus,and Chord ModulusE122 Practice for Calculating Sample Size to Estimate,WithSpecified Precision,the Average for a Characteristic of aLot or ProcessE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE251 Test Methods for Performance Characteristics of Me-tallic Bonded Resistance Strain GagesE456 Terminology Relating to Quality and StatisticsE1237 Guide for Installing Bonded Resistance Strain GagesE1309 GuideforIdentificationofFiber-ReinforcedPolymer-Matrix Composite Materials in Databases(With-drawn 2015)3E1434 Guide for Recording Mechanical Test Data of Fiber-Reinforced Composite Materials in Databases(Withdrawn2015)3E1471 Guide for Identification of Fibers,Fillers,and CoreMaterials in Computerized Material Property Databases(Withdrawn 2015)31This 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 Jan.1,2017.Published January 2017.Originallyapproved in 1993.Last previous edition approved in 2010 as D5467/D5467M 97(2010).DOI:10.1520/D5467_D5467M-97R17.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.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 3.Terminology3.1 DefinitionsTerminology D3878 defines terms relatingto high-modulus fibers and their composites.TerminologyD883 defines terms relating to plastics.Terminology E6 definesterms relating to mechanical testing.Terminology E456 andPractice E177 define terms relating to statis
