Designation:C135813Standard Test Method forMonotonic Compressive Strength Testing of ContinuousFiber-Reinforced Advanced Ceramics with Solid RectangularCross-Section Test Specimens at Ambient Temperatures1This standard is issued under the fixed designation C1358;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.1.Scope*1.1 This test method covers the determination of compres-sive strength including stress-strain behavior under monotonicuniaxial loading of continuous fiber-reinforced advanced ce-ramics at ambient temperatures.This test method addresses,but is not restricted to,various suggested test specimengeometries as listed in the appendix.In addition,test specimenfabrication methods,testing modes(force,displacement,orstrain control),testing rates(force rate,stress rate,displace-ment rate,or strain rate),allowable bending,and data collec-tion and reporting procedures are addressed.Compressivestrength as used in this test method refers to the compressivestrength obtained under monotonic uniaxial loading wheremonotonic refers to a continuous nonstop test rate with noreversals from test initiation to final fracture.1.2 This test method applies primarily to advanced ceramicmatrix composites with continuous fiber reinforcement:uni-directional(1D),bi-directional(2D),and tri-directional(3D)or other multi-directional reinforcements.In addition,this test method may also be used with glass(amorphous)matrix composites with 1D,2D,3D,and other multi-directional continuous fiber reinforcements.This test methoddoes not directly address discontinuous fiber-reinforced,whisker-reinforced,or particulate-reinforced ceramics,al-though the test methods detailed here may be equally appli-cable to these composites.1.3 The values stated in SI units are to be regarded as thestandard and are in accordance with SI 10-02 IEEE/ASTM SI10.1.4 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.Refer to Section 7for specific precautions.2.Referenced Documents2.1 ASTM Standards:2C1145 Terminology of Advanced CeramicsD695 Test Method for Compressive Properties of RigidPlasticsD3379 Test Method for Tensile Strength and Youngs Modu-lus for High-Modulus Single-Filament MaterialsD3410/D3410M Test Method for Compressive Properties ofPolymer Matrix Composite Materials with UnsupportedGage Section by Shear LoadingD3479/D3479M Test Method for Tension-Tension Fatigueof Polymer Matrix Composite MaterialsD3878 Terminology for Composite MaterialsD6856 Guide for Testing Fabric-Reinforced“Textile”Com-posite MaterialsE4 Practices for Force Verification of Testing MachinesE6 Terminology Relating to Methods of Mechanical TestingE83 Practice for Verification and Classification of Exten-someter SystemsE337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet-and Dry-Bulb Tem-peratures)E1012 Practice for Verification of Testing Frame and Speci-men Alignment Under Tensile and Compressive AxialForce ApplicationSI 10-02 IEEE/ASTM SI 10 American National Standardfor Use of the International System of Units(SI):TheModern Metric System3.Terminology3.1 Definitions:3.1.1 The definitions of terms relating to compressivetesting,advanced ceramics,and fiber-reinforced composites,1This test method is under the jurisdiction of ASTM Committee C28 onAdvanced Ceramics and is the direct responsibility of Subcommittee C28.07 onCeramic Matrix Composites.Current edition approved Feb.15,2013.Published March 2013.Originallyapproved in 1996.Last previous edition approved in 2011 as C1358 11.DOI:10.1520/C1358-132For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 appearing in Terminology E6,Test Method D695,PracticeE1012,Terminology C1145,Test Method D3410/D3410M,and Terminology D3878 apply to the terms used in this testmethod.Pertinent definitions are shown as follows with theappropriate source given in parentheses.Additional terms usedin conjunction with this test method are defined in 3.2.3.2 Definitions of Terms Specific to This Standard:3.2.1 advanced ceramic,nhighly engineered,high-performance predominantly non-metallic,inorganic,ceramicmaterial having specific functional attributes.C11453.2.2 axial strain LL1,naverage longitudinal strainsmea
