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

Advanced ceramic, glass, carbon and other fibers are covered by this test standard. 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. Sco Scope pe 1.

Zero the load cell. Check the axial specimen alignment using whatever methods have been established, as described in 7.

By means of our testing expertise and modular product design, we will help find the solution that is right for you. Please help us to share our service with your friends.

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. Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. Link to Active This link will always astk to the current Active version of the standard.

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.

Size px x x x x Means for asttm these fragments for later fractographic reconstruction and analysis is highly recommended.

We need your help to maintenance this website. 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. An appropriate solvent can be used afterwards to remove the vacuum grease.

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.

A fiber is extracted randomly from a bundle or from a spool. This test method constitutes a methodology to obtain the strength of a single fiber.

ASTM C1557 – 14

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. The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. All specimens are loaded to fracture, at a constant rate of cross-head displacement. Originally approved in Monte Carlo Simulation Awtm.

Please fill this form, we will try to respond as soon as possible. The system compliance is determined as follows: This standard does not purport to address all of the safety concerns, if any, associated with aatm use.

Test specimens with at least three different gage lengths, and perform at least, three tests for each value of the gage length. Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. This standard does not purport to address all of the safety concerns, if any, associated with its 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 record.

We are confident that we have what you are looking x1557. The error bars correspond to the largest and smallest values of the errors resulting from repetitions.

No other units of measurement are included in this standard. 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. Force range of 5 kN to kN 1, lbf tolbf Adjustable adtm space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

Last previous edition approved in as C — 03 Handle the test specimen at its ends and avoid touching it in the test gage length. Current edition approved Aug. 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. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area.

Record both the cross-head displacement and force, and strain if applicable.
