1.1 This 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:
1.1.3 Angleply Laminate—Any balanced laminate consisting of ± theta plies where theta is an acute angle with respect to a reference direction. Continuous reinforcing fibers without 0° reinforcing fibers (that is, (±45)ns, (±30)ns, and so forth).
1.1.4 Quasi-Isotropic Laminate—A balanced and symmetric laminate for which a constitutive property of interest, at a given point, displays isotropic behavior in the plane of the laminate. Continuous reinforcing fibers with 0° reinforcing fibers (that is, (0/±45/90)s, (0/±30)s, and so forth).
1.2 The 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.
