ASTM D7905\/D7905M-14<\/h3>\n

Historical Standard: Standard Test Method for Determination of the Mode II Interlaminar Fracture Toughness of Unidirectional Fiber-Reinforced Polymer Matrix Composites<\/h4>\n
\n

ASTM D7905\/D7905M<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method describes the determination of the mode II interlaminar fracture toughness, GIIc<\/sub><\/span>, of unidirectional fiber-reinforced polymer matrix composite laminates under mode II shear loading using the end-notched flexure (ENF) test (Fig. 1<\/span>).<\/p>\n

<\/div>\n<\/p><\/div>\n
\n

1.2<\/span> This method is limited to use with composites consisting of unidirectional carbon-fiber- and glass-fiber-reinforced laminates. This limited scope reflects the experience gained in round robin testing. This test method may prove useful for other types and classes of composite materials; however, certain interferences have been noted (see Section 6<\/span>).<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.<\/p>\n

\n

1.3.1<\/span> Within the text the inch-pound units are shown in brackets.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n

\n

1.4<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
