Context: My postdoctoral fellowship is the contribution of the LTN Laboratory (Laboratoire de Thermocinétique de Nantes) to the "STIICPA" project formed by several industrial and academic partners. The global objective is to reduce CO2 emissions of cars by decreasing their weight. Hence, metallic parts are replaced by composites ones.
Target: Study of the thermoplastic composite parts’ adhesion: the fusion bonding case.
Completed tasks:
Identification of factors influencing the adhesion quality.
Preparation of an experimental device that permits the full control of process conditions (temperature, pressure and cycle time).
Realization of adhesion tests according to a design of experiments.
Characterization of adhesion by peeling tests.
Mechanical calculation of the adhesion and analysis of the factors’ impact.
Calculation of a model representing the bonding force evolution in function of process factors.
Thermo-kinetic simulation confronted to the experimental tests.
