This composite resin consists of UV-curable aliphatic urethane acrylate oligomers and monofunctional acrylate monomers-based resin along with expandable microsphere and fumed silica nanoparticles. Vat photopolymerization process (VPP) is used to fabricate a stable crosslinked matrix that accommodates volumetric expansion in the subsequent steps of thermal and microwave heating. Microwave heating of the samples attains full expansion in under 2 min, compared to 30 min with thermal heating. The degree of curing reached 70.9 % for microwave activation and 36.8 % for thermal, while both the methods exhibited identical density (137 kg/m<sup>3</sup>) but with noticeable differences in internal pore morphology. Thermally foamed samples exhibited higher compressive modulus (6.69 MPa), specific energy absorption (SEA 6.18 J/g), and yield strength of (1.08 MPa) whereas microwave-foamed samples showed higher energy absorption in tension (SEA 1.26 J/g) and faster processing. ANSYS LS-DYNA was used to validate the experimental compressive behavior of the expanded foam activated by both methods. This dual-energy-responsive foam resin enables the digital fabrication of lightweight foams with tunable morphology and mechanical properties.

A key challenge in designing TPV-based components is controlling and predicting the local stress and plastic strains induced during processing. This study examines the application of machine learning (ML) to identify key injection molding parameters that influence TPV mechanical properties and to predict stress–strain behavior for optimized component design. A full factorial design of experiments (DOE) was conducted to produce 32 TPV plaques under varying conditions. Dumbbell-shaped specimens were extracted from the middle and end regions of each plaque in both transverse and longitudinal flow directions. Cyclic tensile tests were performed to measure two target properties: the stress at 30% strain and the plastic strain, or permanent set, after unloading from the 30% strain cycle, yielding a dataset of 128 samples. ML models of varying complexity and interpretability (decision trees, random forests, gradient boosting, and neural networks) were rigorously evaluated using cross-validation and group-splitting. Given multicollinearity among features, optimal feature sets were selected, simultaneously maximizing accuracy and interpretability. While neural networks achieved the highest predictive performance, decision trees provided full interpretability, a valuable trade-off for industrial adoption. Feature importances and SHapley Additive exPlanations (SHAP) revealed that dosage volume and specimen orientation with respect to the flow direction are the most influential parameters.

By integrating Cycle Generative Adversarial Network (CycleGAN) for image enhancement and YOLOv8 for pixel-level segmentation, this method enables comprehensive and automated analysis of Micro-CT scan data, outperforming traditional thresholding, thereby laying the groundwork for high-fidelity numerical simulation. A statistical mean–based reconstruction method is proposed to reconstruct a high-fidelity 3D4DCs RVE model. Numerical results demonstrate significantly improved predictive accuracy, with simulated stress-strain curves showing close alignment with experimental data. It is found that the pressurization process during curing significantly alters the fiber orientation distribution within the composite material, transforming the material from the originally designed approximately transverse isotropy to orthotropic anisotropic composite material. Furthermore, geometric uncertainty systematically reshape the mechanical response landscape: each deformation mode activates distinct micro-structural feature, causing the same spatial variability to impact elastic constants with notably different intensity. As a result, certain properties exhibit high sensitivity while others remain largely unaffected, implying that the degree of dispersion is inherently property-specific. This work not only establishes a “geometry-property” relationship for braided composites but also introduces a novel deep learning-assisted modeling method.
