ASTM D3518/D3518M-94(2001)

Standard Test Method for In-Plane Shear Response of Polymer Matrix Composite Materials by Tensile Test of a &#177 45^o Laminate

SCOPE
1.1 This practice determines the in-plane shear response of polymer matrix composite materials reinforced by high-modulus fibers. The composite material form is limited to a continuous-fiber reinforced composite +45° laminate capable of being tension tested in the laminate chi-direction.  
1.2  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.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
