(Test Method)Standard Test Method for Transverse Tensile Properties of Hoop Wound Polymer Matrix Composite Cylinders
Standard Test Method for Transverse Tensile Properties of Hoop Wound Polymer Matrix Composite Cylinders
SIGNIFICANCE AND USE
This test method is used to produce transverse tensile property data for material specifications, research and development, quality assurance, and structural design and analysis. Factors which influence the transverse tensile response and should, therefore, be reported are: material, methods of material preparation, specimen preparation, specimen conditioning, environment of testing, specimen alignment and gripping, speed of testing, void content, and fiber volume fraction. Properties, in the test direction, which may be obtained from this test method include:
5.1.1 Transverse Tensile Strength,
5.1.2 Transverse Tensile Strain at Failure,
5.1.3 Transverse Tensile Modulus of Elasticity, E22, and
5.1.4 Poisson’Ratio, υ21.
SCOPE
1.1 This test method determines the transverse tensile properties of wound polymer matrix composites reinforced by high-modulus continuous fibers. It describes testing of hoop wound (90°) cylinders in axial tension for determination of transverse tensile properties.
1.2 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.
1.3 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.
