ASTM C1557 Tensile Fibers Test Equipment

Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test d1557. Materials Science Letters, 18, 24,pp.

The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. Historical Version s – view previous versions of standard. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area.

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.

Zero the load cell. 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, asym have a length at least 1. Please fill this form, we will try to respond as soon as possible. Size px x x x x Handle the test specimen at its ends and avoid touching it in the test gage length.

Society, 83, 3,pp. Force range of 5 kN to kN 1, lbf to c155, lbf 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.


Precision and Bias An appropriate solvent can be used afterwards to remove the vacuum grease. Monte Carlo Simulation X1.

However, other gage lengths can be used as long as they are practical, and adtm either case, the value of the gage length must be reported. Please help us to share our service with your friends. No other units of measurement are included in this standard.

The error bars correspond to the largest and smallest values of the errors resulting from repetitions. Center the test specimen over the tab using the printed pattern with one end taped to the tab. For the purpose of determining the parameters of the distribution of fiber strengths it is recommended to follow this test method in conjunction with Practice C Originally approved in 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.

Ideally, an analog chart recorder or plotter shall be used in conjunction with asfm digital data acquisition system to provide an immediate record of the test as a supplement to the digital record. Such non-gage section fractures constitute invalid tests.

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

It is the responsibility of the user of this standard asm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Check the axial specimen alignment using whatever methods have been established, as described in 7. Record both the cross-head displacement and force, and strain if applicable. We are a non-profit group that run this website to share documents.


Alternatively, the sides of the tab can be burned using a soldering iron, for example. The total length of the specimen should be sufficiently long at least 1.

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. This standard does not purport to address all of the safety concerns, if any, associated with its use. We need your help! 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.

This standard does not purport to address all of the safety concerns, if any, associated with its use.


A number in paren parenthese thesess indicates the year of last reappr reapproval. The system compliance is determined as follows: By means of our testing expertise and modular product design, we will help find the solution that is right for you.

Have a question about conducting the test for this standard? 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.
