Impact of Crystallization Rate on Mechanical Properties of Thermoplastic Composite

The main objective for this student team is to assess the effect of Crystallinity degree on mechanical properties of a thermoplastic composite structure. The project is going to be articulated in different steps: -The first step will consist in manufacturing panels in press consolidation with different parameters to change crystallization rate. Time and temperature will be changed - During the 2nd Step: Panels will be checked by carriyng out non destructive control (visual and UT control) - Then DMA tests and DSC will be done to assess thermal transition temperature and degreee of crystallinity. - Flexural specimen will be extracted from panels. Care has to be taken for extraction to ensure no delamination or damages occur during extraction. If necessary, panel could be kept in furnace around 250°C during a defined time and samples will be tested. The deliverable of the project is a report giving impact of crystallization on the material properties.
