Techniques for special material testing
X-ray Diffractometer
The X-ray diffractometer utilizes the diffraction phenomenon of X-rays passing through materials to measure the diffraction angle and diffraction intensity, thereby determining the crystal structure and composition of the material.
Infrared Spectrometer
The infrared spectrometer measures the absorption and emission of infrared radiation by the material, which is used to determine the molecular structure and chemical composition of the material.
Thermal Analysis Instrument
The thermal analysis instrument includes Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA), which measure the changes in thermal performance of the material under different temperature conditions, thereby determining the thermal stability, coefficient of thermal expansion, and other properties of the material.
Steady-State and Transient Thermal Conductivity Tester
The steady-state and transient thermal conductivity tester is used to measure the thermal conductivity of materials, evaluating the thermal insulation performance of the materials.
Destructive and Non-Destructive Testing Equipment
Destructive and non-destructive testing equipment, such as tensile testing machines, impact testing machines, and hardness testers, are used to measure the mechanical properties of materials, evaluating the strength and reliability of the materials.
SEM and TEM
The Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) are used to observe the surface morphology and internal microstructure of materials.

Characterization of Thermal Performance of Fiber Insulation Materials for Building Applications
Tilioua, Amine, Laurent Libessart, and Stéphane Lassue. Applied Thermal Engineering 142 (2018): 56-67.
Fiber insulation materials can effectively control temperature and humidity in building applications. Such materials can minimize the energy input required to maintain a constant temperature. Therefore, the low-density fiber materials exhibit behavior similar to a semi-transparent medium, with the ability to effectively absorb strong anisotropic scattering and emit thermal radiation. The semi-transparent behavior of fiber insulation materials at room temperature has been the subject of extensive research, aiming to describe their thermal performance.
The inverse method is adopted, as it can investigate complex fibrous materials with various fiber sizes, compared to the Mie theory. Through the inverse method based on the experimental measurements of hemispherical reflectance and transmittance, the radiative properties (reflectance, optical thickness, phase function) can be determined. Furthermore, this medium has an optical thickness, and the Rosseland approximation can be used to calculate the radiative thermal conductivity by using the hemispherical measurements with an isotropic phase function.
