Summary

 
Object and purpose of research. This paper studies thermophysical characteristics of sphere-plastic and kinematic parameters of its binder polymerization. Being applied in FEM-based simulation packages, these data will make it possible to calculate optimal parameters for safe thermal conditioning and cooling of large sphere-plastic blocks
Subject matter and methods.Thermophysical and kinematic characteristics of sphere-plastics obtained through dynamic mechanical analysis and differential scanning calorimetry techniques described in ANSYS Composite Cure Simulation user guide.
Main results. Comparison of analytical and experimental data for polymerization and cooling conditions of given sphereplastic composition based on multi-component epoxy binder.
Conclusion. This work explains and demonstrates calculation of optimal polymerization and cooling conditions for a large sphere-plastic block, with determination of time histories for temperature, conversion and internal stresses. The study included the processing of a real block (weight 353 kg) according to the obtained optimal conditions. Direct temperature measurements on the block have shown satisfactory correlation between calculation data and experimental results.
