Infrared technology evaluates the impact of fire on the material

Scientists in Spain have used infrared technology to accurately assess the impact of fire on different materials. This method overcomes the temperature of the flame (over 1,000 ° C) of the flame, which can surpass the material's temperature (heat resistance), according to researchers at Carlos University. III de Madrid (UC3M), Spain.

The results of this study were published in The Journal Measurement Science and Technology.

"We use infrared cameras to measure temperature, as well as image processing, to remove external factors that affect the flame," said Fernando López.

Infrared measurements can be made immediately (in milliseconds) and under extreme fire conditions, so that no other measurement system can be used, according to the researchers.

The researchers are also developing techniques that allow them to measure the distance, the thermodynamic properties of the material, through the infrared analysis of the images.

"The main objective is to measure the actual temperature across the entire surface of the sample, quickly and accurately, including the surface of the sample being covered by the flame and this must be carried out. They are from a distance , " said Professor López.

Researchers hope to find a way to use infrared technology to detect defects hidden under the surface of the material that could be created by fire or other causes.

This research, which could be used in the aerospace industry to look for new materials to make aircraft and to solve problems such as excessive CO ₂ concentrations and water vapor, Visual inspection of samples of materials being tested.

In addition, the results of this study may also be used in other areas: improving the explosion-proof nature of the material is very important for the railways and other transportation vehicles, Fire fighting in the home.

This research is the result of a collaboration between researchers working at Carlos III de Madrid University (UC3M), Spain, with the Airbus Systems Laboratory.
