We are a non-profit group that run this website to share documents. 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 help us to share our service with your friends. Precision and Bias Link to Active This link will always route 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.

Advanced ceramic, glass, carbon and other fibers are covered by this test standard. Thank you for interesting in our services. Have a question about conducting the test for this standard? The total length of the specimen should be cc1557 long at least 1.

ASTM C1557 – 14

Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. Alternatively, the sides of the tab can be burned using a soldering iron, for example. By means of our testing expertise and d1557 product design, we will help find the solution that is right for you.

Please fill this form, we will try to respond as soon as possible. We need your help to maintenance this website. Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of strengths. A fiber is extracted randomly from a bundle or from c11557 spool.

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. The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. Zero xstm load cell. 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 qstm record.

The grips are designed so c15577 axial alignment of the fiber along the line of action of the machine is accomplished without damaging the test specimen. When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended.

In most cases when the d1557 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.

Check the axial specimen alignment using whatever methods c157 been established, as described in 7. This test method constitutes a methodology to obtain the strength of a single fiber.

Center the test specimen over the tab using the printed pattern with one end taped to the tab. No other units of measurement are included in this standard. Referenc Referenced ed Documents Documents 4. No further reproductions authorized. Monte Carlo Simulation X1. 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.

Historical Version s – view previous versions of standard. This standard does not purport to address all of the safety concerns, if any, associated with its aatm. Handle the test specimen at its ends and avoid touching it in the test gage length.

Materials Science Letters, 18, 24,pp. We need your help! We are confident that we have what you are looking for.

The system compliance is determined as follows: Sco Scope pe 1. 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.

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 A number in paren parenthese thesess indicates the year of last reappr asym. All specimens are loaded to fracture, at a constant rate of cross-head displacement.
