Machine Learning‐Assisted Design of Multilayer Thermoplastic Composites: Robust Neural Network Prediction and Feature Importance Analysis
Bibliographic record
Abstract
Abstract Multilayer thermoplastic composites offer sustainable alternatives to traditional thermoset and metal materials. However, their design is inherently complex, involving numerous interdependent parameters that render conventional processes both expensive and time‐consuming. While machine learning‐assisted methods provide a potential solution, they typically require large datasets that can be costly to obtain. This study explores a robust neural network, specifically, an Advanced Multilayer Perceptron (AdvMLP) Regressor, to predict the peel strength of multilayer thermoplastic composites. Through architectural enhancements, the AdvMLP is effectively trained on a limited yet authentic manufacturing dataset, yielding robust predictions validated by benchmark metrics and k‐fold cross‐validation. The model captures the intricate interplay between manufacturing processes and composite properties, enabling comprehensive feature importance analysis and dimensionality reduction. Overall, this study establishes a robust and generalizable machine learning‐assisted methodology to guide and accelerate the design and optimization of multilayer thermoplastic composites.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
