By means of our testing expertise and modular product design, we will help find the solution that is right for you. Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. Originally approved in An appropriate solvent can be used afterwards to remove the vacuum grease.
Record both the cross-head displacement and force, and strain if applicable. 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.

ASTM C1557 – 14
Size px x x x x Monte Carlo Simulation X1. The system compliance is determined as follows: Historical Version s – view previous versions of standard. The mounting tabs are gripped or connected to the load train for example, by pin and clevis so that the test specimen is aligned asttm along the line of action of the test machine.
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. Summ Summary ary of Test Test Method This sta stand ndar ard d may inv involv olvee haz hazar ardo dous us mat materia erials, ls, 1. Handle the test specimen at its ends and avoid touching it in the test gage length. The error bars correspond to the largest and smallest values of the errors resulting from repetitions.
Check the axial specimen alignment using whatever methods have been established, as described in 7.
This standard does not purport to address all of the safety concerns, if any, associated with its use. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended.
Center the test specimen over the tab using the printed pattern with one end taped to the tab. Alternatively, the sides of the tab can be burned using a soldering iron, for example.
Test specimens with at least three different gage lengths, and perform at least, three tests for each value of the gage length. Radial and axial scales are not the same in these diagrams. At the same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that would lead to inaccurate results.
Please copy and paste this astn script to where you want to embed Embed Script. For the purpose of determining the parameters of the distribution of fiber strengths it is awtm to follow this test method in conjunction with Practice C All specimens are loaded to fracture, at a constant rate of cross-head displacement.
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.
Either analog chart recorders or digital data acquisition systems may be used for this purpose although a digital record is recommended for ease of later data analysis. Such non-gage section fractures constitute invalid tests.
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. 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.
A fiber is extracted randomly from a bundle or from a spool. No other units of measurement are included in this standard. We astn 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.
Materials Science Letters, 18, 24,pp. A number in paren parenthese thesess indicates the year of last reappr reapproval. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Ideally, an astj chart recorder or plotter aastm be used in conjunction with the digital data acquisition system to provide an immediate record of the test as a supplement to the digital record. We need your help! Last previous edition approved in as C — 03 This standard does not purport to address all of the safety concerns, if any, associated with its use.
Current edition approved Aug. The total length of the specimen should be sufficiently long at least 1. The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate.
Advanced ceramic, glass, carbon and other fibers are covered by this test standard. We are confident that we have what you are looking for.
ASTM C – 14 – Standard Test Method for Tensile Strength and Young’s Modulus of Fibers
This test method constitutes a methodology to obtain the strength of a single fiber. Give our test engineers a call today for help configuring the best test machine asfm accessories according to your standard. Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. Society, 83, 3,pp. No other units of measurement are included in this standard.
