1. Project Background

Carbon-based materials attract great attention in ultimate material performance verification thanks to their high-temperature resistance. The goal of this test was to tensile-test carbon-based materials at 1000°C in a vacuum furnace to understand their mechanical behavior under extreme heat. To ensure high purity and precision, an inert gas was introduced into the vacuum furnace to protect the specimen, further improving the accuracy of the results.

2. Testing Procedure and Technical Details

Test Setup

1. Preparing the test environment

The carbon-based material specimen was placed in a vacuum furnace heated to 1000°C. To prevent oxidation and impurities from interfering with the results, an inert gas was introduced to create a clean high-temperature environment. The entire process remained oxygen-free and contamination-free, ensuring the material's properties were not altered by oxidation.

2. Key testing points

(1) High-temperature vacuum environment: the vacuum furnace effectively prevents oxidation at high temperature, while the inert gas ensures a pure tensile environment for the carbon-based material, keeping the test highly stable.

(2) Non-contact strain measurement: in a high-temperature environment, conventional contact instruments may be damaged by the extreme heat, so the test adopted Haytham's non-contacthigh-temperature video extensometer for strain measurement, ensuring accurate data acquisition.

(3) Real-time data analysis: during tension, the stress-strain curve of the carbon-based material was recorded in real time, dynamically observing its deformation and fracture behavior and providing a basis for comprehensive analysis of its high-temperature mechanical performance.

3. Test Results and Application Value

The results show that the carbon-based material exhibits excellent heat resistance and strength at 1000°C, providing an accurate reference for its performance data. The test not only verified the material's tensile performance under extreme heat but also provides scientific support for future material development in high-temperature service conditions.
