The GWP offers materialographic investigations of polymer materials and fiber-reinforced plastics using transmitted light microscopy on thin sections. This technique is particularly suitable for analyzing the structural composition of these materials. Thin sections or microtome sections are transparent, so they can be viewed in polarized transmitted light.
By using polarized light, important details in the material can be made visible, including:
- Impurities: Foreign substances and inclusions in the material can be identified.
- melt fronts and weld structures: The quality of weld seams and the orientation of the melt fronts can be analyzed.
- grain boundaries: These are crucial for understanding the material structure and mechanical properties.
- spherulites: The crystalline structures in certain polymers can be investigated and evaluated.
Transmitted light microscopy of thin sections is a valuable method to precisely analyze the microstructure of polymer materials and to draw conclusions about their manufacturing process and quality.
