Optimization of the thermosetting pultrusion process.

Goals of the project
- Optimization of the thermosetting pultrusion process in terms of the quality and quantity of the produced profiles (optimization of the die geometry, pulling speed, temperature regime, composition of the resin);
- Prediction of shape distortions and internal defects of pultrusion profiles immediately after the manufacturing process, as well as after their storage.

Results of the project
- Experiments of thermosetting pultrusion manufacturing process at different pulling speeds, using different reinforcing materials, polymer resins and additives were carried out;

- Experiments were conducted to study the influence of the choice of thermosetting pultrusion technological regimes on the occurrence of shape distortions (spring-in, warping) and cracks in the produced profiles;

- Mathematical model accounting for the influence of the pulling speed of the pultrusion process on the value of the spring-in angle was developed.

- Articles have been published in prestigious scientific journals Q1-Q2, and results have been presented at the international conferences:
