Standard Test Method for
In-Plane Shear Response of Polymer Matrix Composite
Materials by Tensile Test of a 645° Laminate1
This standard is issued under the fixed designation D 3518/D 3518M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1 This test method determines the in-plane shear response
of polymer matrix composite materials reinforced by high-modulus fibres. The composite material form is limited to a
continuous-fibre-reinforced composite 645° laminate capable
of being tension tested in the laminate x-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.
