Standard Guide for Nondestructive Testing of Polymer Matrix Composites Used in Aerospace Applications

ASTM E2533-17 航空航天应用中使用的聚合物基体复合材料无损检测标准指南

1.1 This guide provides information to help engineers select appropriate nondestructive testing (NDT) methods to characterize aerospace polymer matrix composites (PMCs). This guide does not intend to describe every inspection technology. Rather, emphasis is placed on established NDT methods that have been developed into consensus standards and that are currently used by industry. Specific practices and test methods are not described in detail, but are referenced. The referenced NDT practices and test methods have demonstrated utility in quality assurance of PMCs during process design and optimization, process control, after manufacture inspection, in-service inspection, and health monitoring. 1.2 This guide does not specify accept-reject criteria and is not intended to be used as a means for approving composite materials or components for service. 1.3 This guide covers the following established NDT methods as applied to PMCs: Acoustic Emission (AE, 7), Computed Tomography (CT, 8), Leak Testing (LT, 9), Radiographic Testing, Computed Radiography, Digital Radiography, and Radioscopy (RT, CR, DR, RTR, 10), Shearography (11), Strain Measurement (contact methods, 12), Thermography (13), Ultrasonic Testing (UT, 14), and Visual Testing (VT, 15). 1.4 The value of this guide consists of the narrative descriptions of general procedures and significance and use sections for established NDT practices and test methods as applied to PMCs. Additional information is provided about the use of currently active standard documents (an emphasis is placed on applicable standard guides, practices, and test methods of ASTM Committee E07 on Nondestructive Testing), geometry and size considerations, safety and hazards considerations, and information about physical reference standards. 1.5 To ensure proper use of the referenced standard documents, there are recognized NDT specialists that are certified in accordance with industry and company NDT specifications. It is recommended that a NDT specialist be a part of any composite component design, quality assurance, in-service maintenance or damage examination. 1.6 This guide summarizes the application of NDT procedures to fiberand fabric-reinforced polymeric matrix composites. The composites of interest are primarily, but not exclusively limited to those containing high modulus (greater than 20 GPa (3×106 psi)) fibers. Furthermore, an emphasis is placed on composites with continuous (versus discontinuous) fiber reinforcement. 1.7 This guide is applicable to PMCs containing but not limited to bismaleimide, epoxy, phenolic, poly(amide imide), polybenzimidazole, polyester (thermosetting and thermoplastic), poly(ether ether ketone), poly(ether imide), 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 uniaxial laminae, cross-ply laminates, angle-ply laminates, and sandwich constructions. The composite components made therefrom include filament-wound pressure vessels, flight control surfaces, and various structural composites. 1.9 For current and potential NDT procedures for finding indications of discontinuities in the composite overwrap in filament-wound pressure vessels, also known as composite overwrapped pressure vessels (COPVs), refer to Guide E2981. 1.10 For a summary of the application of destructive ASTM standard practices and test methods (and other supporting standards) to continuous-fiber reinforced PMCs, refer to Guide D4762. 1.11 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.12 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 This guide is under the jurisdiction of ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E07.10 on Specialized NDT Methods.

ASTM D8101/D8101M-17 用钝射弹测量复合材料抗穿透性的标准试验方法

5.1 Advanced composite systems are used in a number of applications as shields to prevent penetration by projectiles. In general, the use of composites is more effective for blunt, rather than sharp, projectiles or in hybrid systems in which an additional shield can be used to blunt a sharp projectile. Knowledge of the penetration impact resistance of different material systems or the effects of environmental or in-service load exposure to the penetration resistance of given materials is useful for product development and material selection. 5.2 An impact test used to measure the penetration resistance of a material can serve the following purposes: 5.2.1 To quantify the effect of fiber architecture, stacking sequence, fiber and matrix material selection, and processing parameters on the penetration resistance of different composite materials; 5.2.2 To measure the effects of environmental or in-service load exposure on the penetration impact resistance of a given material system; and 5.2.3 As a tool for quality assurance requirements for materials designed for penetration resistance applications. 5.3 The penetration resistance values obtained with this test method are most commonly used in material specification and selection and research and development activities. The data are not intended for use in establishing design allowables, as the results are specific to the geometry and physical conditions tested and are not generally scalable to other configurations. 5.4 The reporting section requires items that tend to influence the penetration resistance of material systems. These include the following: fiber and matrix materials, fiber architecture, layup sequence, methods of material fabrication, environmental exposure parameters, specimen geometry and overall thickness, void content, specimen conditioning, testing environment and exposure time, specimen fixture and alignment, projectile mass and geometry, and projectile orientation at impact. Additional reporting requirements include size and description of damage, results of any pre- and post-test nondestructive inspection, impact velocity, accuracy of the velocity measurement apparatus, and whether or not the projectile penetrated the panel. Residual velocity is a desirable, but not a necessary, value to be reported. 5.5 The reporting section shall also include the parameters of a statistical function that gives the probability of penetration as a function of impact kinetic energy (see 14.4). 5.6 The relevant measurements that result from the impact test are the kinetic energy and impact velocity of the projectile and whether or not the projectile penetrated the specimen. An optional item to be measured is the loss in kinetic energy of the projectile as a function of impact velocity if measurements of the residual velocity are recorded. 1.1 This test method measures the resistance of flat composite panels in one specific clamping config......
