ASTM C Tensile Fibers Test Equipment

The fiber is mounted in the testing machine, and then stressed to failure at a constant cross-head displacement rate. Single fiber specimens are removed from fiber bundles or spools, should have a length at least 1. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, asgm, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

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

Sco Scope pe 1. Materials Science Letters, 18, 24,pp.

Test specimens with at least three different gage lengths, and perform at least, three tests for each value of the gage length. Please fill this form, we will try to respond as soon as possible. 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 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.

This test method constitutes a methodology to obtain the strength of a single fiber. Size px x x x x Advanced ceramic, glass, carbon and other fibers are covered by this test standard. Originally approved in 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.

Record both the cross-head displacement and force, and strain if applicable. No other units of measurement are included in this standard. Force range of c1575 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.

Monte Carlo Simulation X1. Zero the load cell. The system compliance is determined as follows: No further reproductions authorized.

The total length of the specimen should be sufficiently long at least 1. Please copy and paste this embed script to where you want to embed Embed Script. Very short fibers including whiskers call for specialized test techniques 1 3 and are not covered by this test method.

Center the test specimen over the tab using the printed pattern with one end taped to the tab. We are a non-profit group that run this website to share documents. Check the axial specimen alignment using whatever methods have been established, as described in 7. 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.

Alternatively, the sides of the tab can be burned using a soldering iron, for example.

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

All specimens are loaded to fracture, at a constant rate of cross-head displacement. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.
