Radial and axial scales are not the same in these diagrams. The fiber is mounted in the testing machine, and then stressed to failure c1557 a constant cross-head cc1557 rate. Current edition approved Aug. No further reproductions authorized. Alternatively, the sides of the tab can be burned using a soldering iron, for example. This test method may also be useful in the initial screening of candidate fibers for applications in polymer, metal or ceramic matrix composites, and quality control purposes.

Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test method. In most cases when the strength of the fibers is controlled by one population of flaws, the distribution of fiber strengths can be described using a two-parameter Weibull distribution, although other distributions have also been suggested 23.

The mounting tabs are gripped or connected to the load train for example, by pin and clevis so that the test specimen is aligned axially along the line of action of the test machine.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A fiber is extracted randomly from a bundle or from a spool.

ASTM C – 14 Standard Test Method for Tensile Strength and Young’s Modulus of Fibers

Have a question about conducting the test for this standard? Such non-gage section fractures constitute invalid tests. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.

However, other gage lengths can be used as long as they are practical, and in either case, the value of the gage length must be reported. An appropriate solvent can be used afterwards to remove the vacuum grease. Please fill this form, we will try to respond as soon as possible. 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.

Ideally, an analog chart recorder or plotter shall be used in conjunction with the digital data acquisition system to provide an immediate record of the test as a supplement to the digital c5157. The total length of the specimen should be sufficiently long at least 1. We are confident that we have what you are looking for. The error bars correspond to the largest and smallest values of the errors resulting from repetitions.

This standard does not purport to address all of the safety concerns, if any, associated with its use. We are a non-profit group that run this website to share documents. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

No other units of measurement are included in this standard. ASTM C is the standard test method for determining the tensile strength and elastic Young’s modulus of single ceramic, glass, carbon and other fibers at ambient temperature. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

This test method constitutes a methodology to obtain the strength of a single fiber. The grips are designed so that axial alignment of the fiber along the line of action of the machine is accomplished without damaging the test specimen. Center the test specimen over the tab using the printed pattern with one end taped to the tab.
