Fiber membrane material tensile testing machineProfessional testing of tensile mechanical properties of high-tech composite materials

Product Introduction

Fiber membrane material tensile testing machineIt is a precision mechanical testing system designed specifically for fiber-reinforced composite materials, coated fabrics, flexible films, and various high-performance textile structural materials. This type of material is widely used in large building membrane structures, environmental engineering, aerospace components, outdoor equipment, and special industrial fabrics. Its tensile strength, tensile elasticity, and durability are the key factors determining the final product performance. This equipment is designed to provide high-precision and highly repeatable professional testing solutions for the production, manufacturing, quality monitoring, research and development innovation, and standard compliance certification of the above-mentioned materials.

The device adopts an innovative design concept of combining rigidity and flexibility, with a high rigidity frame as the main body, ensuring the stability of the system under high loads, while maintaining a keen response to subtle changes in flexible materials through low inertia design. The system core integrates a high-precision force sensing unit, a fully digital servo drive system, and intelligent measurement and control software, which can accurately perform comprehensive performance evaluation of materials under uniaxial tension. Its design and operating procedures strictly follow domestic and international standards such as GB/T, ASTM D751, ISO 1421, ensuring the scientific rigor and wide comparability of test results. It is a core testing equipment for composite material manufacturers, testing laboratories, research institutes, and large-scale engineering project quality supervision.

Core functional advantages

Testing ability and flexibility

Wide force coverage: Equipped with high-sensitivity sensors, the testing range can be extended from several newtons to thousands of newtons, easily meeting different testing needs from thin and flexible films to high-strength fiber fabrics.

Precise strain measurement solution: Standard configuration or recommended selection of non-contact video extensometer to achieve non-destructive and high-precision measurement of surface strain of the specimen, solving the interference and damage problems caused by traditional contact measurement on soft, smooth or vulnerable specimens.

Diversified testing modes: In addition to basic tensile to failure tests, it also supports various specialized tests such as elongation testing under constant load, load retention testing under specified elongation, elastic recovery rate determination, and peel strength testing, fully meeting the diversified needs of material research and quality evaluation.

Intelligent control and safety experience

Fully automatic programmable testing: Based on a microcomputer servo control system, it allows users to accurately program displacement, velocity, etc., supports complex multi-step cyclic loading, and simulates the complex stress conditions experienced by materials in actual use.

Real time process visualization: During the testing process, the control software interface dynamically displays the "force displacement" and "stress-strain" curves in real time. If equipped with a video extensometer, it can also synchronously observe the real-time deformation image of the sample surface, making the entire testing process clear and transparent.

Comprehensive security mechanism: Built in multiple electronic and mechanical safety protections, such as overload automatic protection, travel limit protection, automatic identification and shutdown of sample fracture, etc., fully ensuring the safety of operators and the long-term reliable operation of equipment.

Efficient data processing and reporting system

One click intelligent analysis: After the experiment is completed, the system automatically processes the raw data and instantly calculates a complete set of key mechanical performance parameters, including maximum tensile strength, tensile strength, elongation at break, secant modulus, and yield point.

Standardized report output: Based on preset or custom templates, a standardized testing report containing all test data, complete curve graphs, and statistical results can be generated with just one click. Data and reports support electronic archiving, export, and traceability, greatly facilitating laboratory quality document management.

Test principle description

The equipment follows the internationally recognized standard for tensile testing, and its process is precise and controllable, mainly divided into three steps:

1. Sample preparation and clamping: The strip sample prepared strictly according to the standard will be accurately aligned and clamped using a dedicated pneumatic flat pushing fixture or a low-pressure jaw fixture with a buffer pad. This design can effectively disperse the pressure in the clamping area, avoid stress concentration at the clamping edge and prevent premature failure or slippage of the sample, ensuring that the measured material's true properties are obtained.

2. Precise force application and synchronous measurement: Start the equipment after setting the initial gauge length and test speed. The servo drive system smoothly pulls the moving crossbeam and applies a uniformly increasing axial tension to the specimen. High precision force sensors monitor load changes throughout the entire process, while high-resolution extensometers (especially video extensometers) synchronously track and calculate the true strain values within the sample gauge range.

3. Data collection and intelligent analysis: The control system continuously collects and records load and deformation data, and draws real-time relationship curves. When the sample breaks, the test automatically ends. The software then uses built-in standard algorithms to intelligently analyze the entire process data, ultimately outputting a series of quantified material performance parameters, and presenting professional and intuitive analysis results in the form of a report with graphics and text.
