It is the responsibility of the user of this standard to establish appropriate This standard does not purport to address all of the safety concerns, if any, associated with its use. Combining values from the two systems may result in nonconformance with the standard. The values stated in each system are not exact equivalents therefore, each system must be used independently of the other. Within the text, the inch-pound units are shown in brackets. The values stated in either SI units or inch-pound units are to be regarded separately as standard.
The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. This test method determines the in-plane tensile properties of polymer matrix composite materials reinforced by high-modulus fibers. Ultimate tensile strength Ultimate tensile strain Tensile chord modulus of elasticity Poisson's ratio Transition strain Properties, in the test direction, which may be obtained from this test method include the following: Factors that influence the tensile response and should therefore be reported include the following: material, methods of material preparation and lay-up, specimen stacking sequence, specimen preparation, specimen conditioning, environment of testing, specimen alignment and gripping, speed of testing, time at temperature, void content, and volume percent reinforcement.
The values given in parentheses are for information only.ġ.1.2 ASTM D3039 / D3039M – 08 Standard Test Method for Tensile Properties of Polymer Matrix Composite Materials This test method is designed to produce tensile property data for material specifications, research and development, quality assurance, and structural design and analysis. The values stated in SI units are to be regarded as standard. Test data obtained by this test method are relevant and appropriate for use in engineering design. This test method includes the option of determining Poisson's ratio at room temperature.
However, for testing specimens in the form of thin sheeting, including film less than 1.0 mm (0.04 in.) in thickness. This test method can be used for testing materials of any thickness up to 14 mm (0.55 in.). Under defined conditions of pretreatment, temperature, humidity, and testing machine speed. This test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested
Similarly, for referee purposes or comparisons within any given series of specimens, care must be taken to secure the maximum degree of uniformity in details of preparation, treatment, and handling. Hence, when comparative tests of materials per se are desired, the greatest care must be exercised to ensure that all samples are prepared in exactly the same way, unless the test is to include the effects of sample preparation. It is realized that a material cannot be tested without also testing the method of preparation of that material. Consequently, where precise comparative results are desired, these factors must be carefully controlled. Tensile properties may vary with specimen preparation and with speed and environment of testing. For many materials, there may be a specification that requires the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. These data are also useful for qualitative characterization and for research and development. ASTM, founded in 1898 as the American Section of the International Association for Testing and Materials, predates other standards organizationsġ.1 ASTM Standards for Polymer Tensile Testing ĪSTM D638 – 10 ASTM D3039 / D3039M – 08 ASTM D5083 – 10 ASTM D882 – 12 ASTM D1822 – 06ġ.1.1 ASTM D638 - 10: Standard Test Method for Tensile Properties of Plastics This test method is designed to produce tensile property data for the control and specification of plastic materials.
