Glass Fiber Material Tensile Test

Glass fiber materials are widely used in aerospace, construction, automotive, and other industries thanks to their light weight and high strength. To ensure the reliability of glass fiber materials in practical applications, testing their mechanical properties, especially tensile properties, is particularly important. Conventional tensile testing methods usually rely on contact extensometers or strain gauges, which can face problems such as difficult installation and limited measurement accuracy when dealing with the complex deformation of fiber materials.

1. Testing Process

The Haytham monocular 3D video extensometer was adopted for this tensile test of glass fiber material. Before testing, the specimen was clamped in the tensile testing machine, and the extensometer captured the surface deformation of the glass fiber specimen during tension through a monocular camera. The device analyzes the acquired images using digital image correlation (DIC) technology and computes the strain distribution of the specimen in real time.

Glass fiber fracture process

Because glass fiber materials may exhibit complex phenomena such as localized deformation concentration and fracture during tension, the non-contact measurement of the Haytham monocular 3D video extensometer avoids the interference and errors that can be caused by attaching a conventional extensometer to the specimen surface. In addition, the device provides real-time full-field strain data of the specimen during tension, which is essential for understanding the tensile performance and fracture mechanism of the material.

2. Test Results

In this test, the Haytham monocular 3D video extensometer successfully captured the strain distribution and deformation behavior of the glass fiber material during tension. The test data revealed the tensile performance of the material under different stress states, including key mechanical parameters such as elastic modulus and fracture strain. These data provide an important reference for evaluating the performance of glass fiber materials in practical applications.
