High modulus fiber single fiber tensile properties test method
1 Scope
This standard specifies the test method for the tensile properties of single fibers with high modulus fibers.
This standard applies to high modulus fibers, other chemical fibers can refer to use.

3 Terms and definitions
The terms and definitions defined in GB/T 4146 (all parts) and the following apply to this document.
3.1
Tensile modulus
The ratio of stress increment to strain increment between two points is specified on the strength-elongation curve.
3.2
System compliance K systemcomplianceK
Correction factor for indicating elongation due to loading system and specimen clamping system.
3.3
Sample pad specificationmounting
Support the shim held by the specimen.
4 Principle
The single fiber is stretched to break on the constant velocity elongation extensometer under the specified conditions, from the strength-elongation curve or data display acquisition system
The measured values such as breaking strength and breaking elongation of the sample are obtained in.
Combining the fiber cross-sectional area or linear density to calculate the breaking strength, tensile modulus, etc.
The strength and elongation during the stretching process may be non-linear, and the tensile modulus should be calculated to define the position of the string.
The tensile modulus needs to be corrected according to the system compliance.
5 Instruments and materials
5.1 Tensile testing machine (constant speed extension type)
5.1.1 The tensile testing machine should be equipped with the following devices.
