1、Designation:C183616Standard Classification forFiber Reinforced Carbon-Carbon Composite Structures1This standard is issued under the fixed designation C1836;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A n
2、umber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This classification covers fiber reinforced carbon-carbon(C-C)composite structures(flat plates,rectangular bars,roundrods,and tubes)manufact
3、ured specifically for structural com-ponents.The carbon-carbon composites consist of carbon/graphite fibers(from PAN,pitch,or rayon precursors)in acarbon/graphite matrix produced by liquid infiltration/pyrolysis or by chemical vapor infiltration,or both.1.2 The classification system provides a means
4、 of identify-ing and organizing different C-C composites,based on the fibertype,architecture class,matrix densification,physicalproperties,and mechanical properties.The system provides atop-level identification system for grouping different types ofC-C composites into different classes and provides
5、a means ofidentifying the general structure and properties of a given C-Ccomposite.It is meant to assist the ceramics community indeveloping,selecting,and using C-C composites with theappropriate composition,construction,and properties for aspecific application.1.3 The classification system produces
6、 a classification codefor a given C-C composite,which shows the type of fiber,reinforcement architecture,matrix type,fiber volume fraction,density,porosity,and tensile strength and modulus(roomtemperature).1.3.1 For example,Carbon-Carbon Composites Classifica-tion Code,C3-A2C-4C2*-32classification o
