“STTC ApATeCh-Dubna” competence in pultrusion is based on the methods of mathematical simulation. Mathematical model allows to optimize the necessary parameters of this process in order to get a high quality product with minimal cost price. Simulation gives an opportunity to estimate modes of the pultrusion process (speed of pulling out, temperature) according to the shape and the section area of the pulled-out glass-fiber structures, thus achieving the set goal.

Tasks and objectives of mathematical simulation

• No production defects
• To keep the required geometry
• Curing
• Heat expansion analysis
• Analysis of the curing process
• Defining the fields of stress and deformation
• Thermal and mechanical properties of a die and resin
• Kinetic parameters of curing
• Temperature of the die
• Speed of pulling out
• To combine the curing process with the speed of pulling out
• To adjust the components ratio in a composite product
