The error bars correspond to the largest and smallest values of the errors resulting from repetitions. Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution of astk. 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.
Center the test specimen over the tab using the printed pattern with one end taped to the tab.
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. Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended. Size px x x x x Have a question about conducting the test for this standard?

ASTM C1557 Tensile Fibers Test Equipment
A fiber is extracted randomly from a bundle or from a spool. The system compliance is determined as follows: This standard does not purport to address all of the safety concerns, if any, associated with its use.
Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. All specimens are loaded to fracture, at a constant rate of cross-head displacement. By means of our testing expertise and modular product design, we will help find the solution that is right for you. However, other gage lengths can xstm used as long as they are practical, and in either case, the value of the gage length must be reported.
ASTM C – 03e1 Standard Test Method for Tensile Strength and Youngs Modulus of Fibers
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. Record both the cross-head displacement and force, and strain if applicable. 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.

ASTM C – 14 – Standard Test Method for Tensile Strength and Young’s Modulus of Fibers
The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. Such non-gage section fractures constitute invalid tests.
At c15557 same time, the grip facing material must prevent crushing, scoring or other damage to the test specimen that would lead to inaccurate results. 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.
