1.    Material state and mathematical modelling of thermoplastic prepreg forming, including draping simulation with taking into account phase transition.

This project models manufacturing processes of composite parts made of thermoplastic prepregs. The growing market of thermoplastic composites demands the development of solutions to model the deformation process of soft thermoplastic prepregs and its crystallization process and phase transition into solid state. New constitutive equations are going to be developed, as well as related experimental and verification approaches.

2.    Development and modelling of advanced structures based on new materials and new technologies.

The project is supposed to develop new models for new materials with specific features for manufacturing. The project will estimate strength characteristics of advanced composites parts and develop certification standards based on new mathematical models. Optimization of manufacturing parameters to increase the quality of produced composite structures is going to be performed.
