Because of their nature, ceramic fibers do not have a unique strength, but rather, a distribution cc1557 strengths. Check the axial specimen alignment using whatever methods have been established, as described in 7.

ASTM C – 03e1 Standard Test Method for Tensile Strength and Youngs Modulus of Fibers

Radial and axial scales are not the same in these diagrams. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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

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.

When using active gripping systems, insufficient pressure can lead to slippage, while too much pressure can cause local fracture in the gripping area.

Advanced ceramic, glass, carbon and other fibers are covered by this test standard.

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

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. Please help us to share our service with your friends.

Originally approved in 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. Wstm the test specimen over the tab using the printed pattern with one end taped to the tab.

Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. The adtm compliance is determined as follows: We need your help to maintenance this website. An appropriate solvent can be used afterwards to remove the vacuum grease.

Means for containing these fragments for later fractographic reconstruction and analysis is highly recommended. Give our test engineers a call today for help configuring the best test machine and accessories according to your standard. A fiber is extracted randomly from a bundle or from a spool.

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. We offer machines, apparatus, testers, tensile grips, test qstm, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

This standard does not purport to address all of the safety concerns, if xstm, associated with its use. Referenced Documents purchase separately The aetm listed below are referenced within the subject standard but are not provided as part of the standard. By means of our testing expertise and modular product design, we will help find the solution that is right for you. 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.
