1、Designation: D7332/D7332M 09D7332/D7332M 15Standard Test Method forMeasuring the Fastener Pull-Through Resistance of aFiber-Reinforced Polymer Matrix Composite1This standard is issued under the fixed designation D7332/D7332M; the number immediately following the designation indicates theyear of orig
2、inal 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 determines the fastener pull-through resistanc
3、e of multidirectional polymer matrix composites reinforcedby high-modulus fibers. Fastener pull-through resistance is characterized by the force-versus-displacement response exhibitedwhen a mechanical fastener is pulled through a composite plate, with the force applied perpendicular to the plane of
4、the plate. Thecomposite material forms are limited to continuous-fiber or discontinuous-fiber (tape or fabric, or both) reinforced composites forwhich the laminate is symmetric and balanced with respect to the test direction. The range of acceptable test laminates andthicknesses is defined in 8.2.1.
5、2 Two test procedures and configurations are provided. The first, Procedure A, is suitable for screening and fastenerdevelopment purposes. The second, Procedure B, is configuration-dependent and is suitable for establishing design values. Bothprocedures can be used to perform comparative evaluations
6、 of candidate fasteners/fastener system designs.1.3 The specimens described herein may not be representative of actual joints which may contain one or more free edgesadjacent to the fastener, or may contain multiple fasteners that can change the actual boundary conditions.1.4 This test method is con
7、sistent with the recommendations of CMH-17, which describes the desirable attributes of a fastenerpull-through test method.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text theinch-pound units are shown in brackets. The values sta
8、ted in each system are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.
