FXW121-II Engineering Short Fiber Strength Tester
Product Introduction
The FXW121-II Engineering Short Fiber Strength Tester is specially designed for measuring the breaking strength and elongation at break of short fibers shorter than 10 mm that are difficult to grip using conventional tensile testing equipment.
The tester is applicable to synthetic fibers used in cement concrete and mortar and complies with the test method specified in Appendix A of GB/T 21120-2007, covering breaking strength, initial modulus and elongation at break of synthetic fibers.
With a servo drive system, precision ball screw transmission and high-resolution rotary encoder, the FXW121-II provides stable mechanical movement, low operating noise and precise elongation measurement. Its dedicated workstation also allows operators to perform testing comfortably while seated.

Performance Features
•   Specially designed for short fibers below 10 mm that are difficult to clamp.
•   Powder-coated housing provides a durable external finish.
•  Metal panel, metal keys and key clamping components use aluminum alloy construction.
•   Dedicated test table supports comfortable seated operation.
•   Servo drive and motor provide stable operation and a wide speed ratio range.
•   Precision ball screw and guide rod transmission improves running stability and reduces vibration and noise.
•  Rotary encoder provides high-resolution elongation measurement down to 0.01 mm.
• Computer and printer configuration supports online testing and report generation.
•   Displays real-time force–elongation curves.
•  Curves can be overlaid, enlarged at selected points and saved for later analysis.
•  Test reports support Chinese/English output and metric/imperial unit conversion.
•   Curve point-reading function can obtain elongation values at six selected force points or force values at six selected elongation points.
•   Digital force calibration requires no mechanical component adjustment.
• Elongation calibration can be completed by directly entering the actual elongation value.

Working Principle
The short fiber specimen is securely positioned using the dedicated clamping mechanism. The servo motor drives the precision transmission system at the preset test speed, applying tensile force to the specimen until rupture.
During testing, the system continuously records the force and elongation. The rotary encoder measures specimen elongation with a resolution of up to 0.01 mm, while the force measurement system records the applied tensile load. The software generates a force–elongation curve and allows selected points to be analyzed for breaking strength and elongation.
After testing, the software can save curves, overlay multiple curves, perform curve-point readings and generate test reports.
