ASTM D3552-24 PDF

1.1This test method covers the determination of the tensile properties of metal matrix composites reinforced by continuous and discontinuous high-modulus fibers. Nontraditional metal matrix composites as stated in 1.1.6 also are covered in this test method. This test method applies to specimens loaded in a uniaxial manner tested in laboratory air at either room temperature or elevated temperatures. The types of metal matrix composites covered are:

1.1.1Unidirectional laminates (all fibers aligned in a single direction) containing either continuous or discontinuous reinforcing fibers. Both longitudinal and transverse properties may be obtained.

1.1.20°/90° balanced crossply laminates containing either continuous or discontinuous reinforcing fibers.

1.1.3Angleply laminates containing continuous reinforcing fibers, with layups that do not include 0° reinforcing fibers (that is, (±45)_ns, (±30)_ns, and so forth).

1.1.4Multidirectional laminates containing continuous reinforcing fibers, with layups including 0° reinforcing fibers (that is, (0/±45/90)_ns quasi-isotropic laminates, (0/±30)_ns laminates, and so forth).

1.1.5Laminates containing unoriented and random discontinuous fibers.

1.1.6Directionally solidified eutectic composites.

1.2The technical content of this standard has been stable since 1996 without significant objection from its stakeholders. As there is limited technical support for the maintenance of this standard, changes since that date have been limited to items required to retain consistency with other ASTM D30 Committee standards. The standard therefore should not be considered to include any significant changes in approach and practice since 1996. Future maintenance of the standard will only be in response to specific requests and performed only as technical support allows.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
