Standard Test Method for Tensile Strength and Young's Modulus of Fibers

Importancia y uso:

5.1 Properties determined by this test method are useful in the evaluation of new fibers at the research and development levels. Fibers with diameters up to 250 × 10^–6 m are covered by this test method. Very short fibers (including whiskers) call for specialized test techniques (1)3 and are not covered by this test method. This test method may also be useful in the initial screening of candidate fibers for applications in polymer, metal, or ceramic matrix composites, and for quality control purposes. Because of their nature, ceramic fibers do not have a unique tensile strength, but rather a distribution of tensile strengths. In most cases when the tensile strength of the fibers is controlled by one population of flaws, the distribution of fiber tensile strengths can be described using a two-parameter Weibull distribution, although other distributions have also been suggested (2, 3). This test method constitutes a methodology to obtain the tensile strength of a single fiber. For the purpose of determining the parameters of the distribution of fiber tensile strengths, it is recommended to follow this test method in conjunction with Practice C1239.
