1、Designation: E 2533 09Standard Guide forNondestructive Testing of Polymer Matrix Composites Usedin Aerospace Applications1This standard is issued under the fixed designation E 2533; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, t
2、he 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. Scope1.1 This guide provides information to help engineers selectappropriate nondestructive testing (NDT) methods to
3、 charac-terize aerospace polymer matrix composites (PMCs). Thisguide does not intend to describe every inspection technology.Rather, emphasis is placed on established NDT methods thathave been developed into consensus standards and that arecurrently used by industry. Specific practices and test meth
4、odsare not described in detail, but are referenced. The referencedNDT practices and test methods have demonstrated utility inquality assurance of PMCs during process design and optimi-zation, process control, after manufacture inspection, in-service inspection, and health monitoring.1.2 This guide d
5、oes not specify accept-reject criteria and isnot intended to be used as a means for approving compositematerials or components for service.1.3 This guide covers the following established NDT meth-ods as applied to polymeric matrix composites: AcousticEmission, Computed Tomography, Leak Testing, Radi
6、ography,Radioscopy, Shearography, Strain Measurement (contact meth-ods), Thermography, Ultrasound, and Visual NDT.1.4 The value of this guide consists of the narrative descrip-tions of general procedures and significance and use sectionsfor established NDT methods as applied to polymer matrixcomposi
7、tes. Additional information is provided about the useof currently active standard documents (an emphasis is placedon applicable standard guides, practices, and test methods ofASTM Committee E07 on Nondestructive Testing), geometryand size considerations, safety and hazards considerations, andinforma
8、tion about physical reference standards.1.5 To ensure proper use of the referenced standard docu-ments, there are recognized NDT specialists that are certified inaccordance with industry and company NDT specifications. Itis recommended that a NDT specialist be a part of anycomposite component design

10、GPa(33106psi) fibers. Furthermore, an emphasis is placed oncomposites with continuous (versus discontinuous) fiber rein-forcement.1.7 This guide is applicable to polymeric matrix compositescontaining but not limited to bismaleimide, epoxy, phenolic,poly(amide imide), polybenzimidazole, polyester (th
11、ermoset-ting and thermoplastic), poly(ether ether ketone), poly(etherimide), polyimide (thermosetting and thermoplastic),poly(phenylene sulfide), or polysulfone matrices; and alumina,aramid, boron, carbon, glass, quartz, or silicon carbide fibers.1.8 The composite materials considered herein include
12、uniaxial laminae, cross-ply laminates, angle-ply laminates, andstructural sandwich constructions. The composite componentsmade therefrom include filament-wound pressure vessels,flight control surfaces, and various structural composites.1.9 The values stated in SI units are to be regarded as thestand
