Abstract

fetched live from OpenAlex

This work presents the development of a comprehensive model to describe the cure kinetics and viscosity behaviour of polyester-based resin systems used in liquid composite moulding applications. The model accounts for both inhibition and diffusion effects, providing a unified equation that simplifies the complex integral expressions often required in sequential or piecewise approaches. Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC), and rheological characterization were performed to assess the thermal stability, curing behaviour, and viscosity changes over a range of isothermal temperatures. Time-temperature graphs generated by the model highlight critical regions for processing, including the processability window and the rapid crosslinking region. These insights are crucial for optimizing process parameters in the large-scale manufacturing of composite parts, particularly for complex geometries. • A novel cure kinetics model that accounts for inhibition and diffusion effects. • A viscosity model coupled with the cure kinetics model and inhibition effects. • Processability maps show the available injection time vs. process temperature. • Simulation compares HPRTM of polyester with inhibitor vs. highly reactive resin.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
