Beschreibung: It is well known that composite materials used in modern armor systems, especially polymers, are prone to ageing effects. This becomes a crucial subject when ageing causes a loss in the mechanical performance, which could also result in a loss in the ballistic protection performance.
Here we propose a study of the different parameters (e.g., temperature, humidity, UV, etc.) that are main factors of ageing. The work will focus on a selection of protection materials that are commonly used, and the chosen materials will be artificially aged in-house.
The characterization, analysis and comparison of the aged and non-aged materials will be performed. Therefore, materials are physically and chemically characterized in a thorough way with traditional methodology (RAMAN, SEM-EDX, Microscopy, SAXS/WAXS, thermal analysis, etc.) but also with a very promising ISL non-destructive-approach THz-TDS/millimeter-wave FMCW technique and Synchrotron experiments. Moreover, the mechanical and ballistic performance of non-aged and aged materials will be investigated.
The student will work at the ISL (French-German Research Institute of Saint-Louis) and the IS2M (Institute of Material Science of Mulhouse). This highly interdisciplinary project will allow the student to get a broad knowledge in different techniques and work in an international environment.

Knowledge requirements:
- Polymers and/or composites
- Data analysis (PCA etc.)
- Basic knowledge of RAMAN and SAXS/WAXS is an advantage
Methoden: The work will be articulated in the following work packages:
1) Establishing a characterization methodology.
2) Investigation of the ageing effects caused by each of the parameters considered.
3) Study of the ageing effects through a combination of the different parameters considered.
4) Data analysis (PCA, Chimiometry etc).
5) Ballistic performance evaluation.
6) Classification of the ageing sensitivity/causes of the materials considered.
