2300℃ High-Temperature Compression Test of Composite Materials (No Marking Points)

In materials science, composites are widely used in aerospace and energy for their strength and heat resistance. Their behavior must be measured under extreme temperatures to ensure reliability in real service. Marker-free non-contact DIC captures full-field compression deformation at 2300°C for trustworthy verification.

High-temperature full-field strainDIC technology
Full-Field Test of 3D-Printed Alloy Component with Heating to 350℃

As 3D printing spreads across aerospace and automotive manufacturing, material performance is a core design and production concern. A well-known manufacturer developing a 3D-printed alloy component for high-temperature service needed full-field data under heating to 350°C. Non-contact DIC delivered complete strain fields, supporting reliable performance verification.

Rebar tensile testingHigh-temperature extensometer
High-Temperature Tensile Test of Rebar (Featureless Recognition)

In steel performance evaluation, high-temperature tensile testing verifies heat resistance and plasticity. For rebar with rough, reflective, complex surfaces, traditional contact extensometers often fail to work stably. Haytham's featureless recognition measures strain without surface preparation for stable high-temperature data.

Lithium Battery Nail Penetration Test

The nail penetration test simulates internal short circuit scenarios in battery cells. Traditional approaches focus on a single physical quantity such as temperature or displacement and strain, making it hard to answer where the heat starts and how it spreads, or how mechanical deformation interacts with the temperature rise. Haytham brings full-field deformation measurement into the test to capture both together.

Material tensile testingVideo extensometer
1500℃ Tensile Test of Carbon/Carbon Composite

In 1500°C tensile testing of carbon/carbon (C/C) composites, the material endures strong radiation, high heat flux, and a complex atmosphere. Traditional contact extensometers and strain gauges fail or detach under such conditions. Non-contact DIC withstands the extreme environment for reliable full-field strain data.
