The hyperparameters are optimized for both the forward and inverse sub-models, which enables the newly proposed dual-network model to have excellent prediction and design capabilities.

Traditional composite manufacturing via filament winding requires prolonged post-winding thermal curing, often for several hours in an oven or autoclave, resulting in long cycle times, low production rates, and high energy consumption. Here, we present a one-step, rapid, and energy-efficient approach for <em>in-situ</em> curing of composites during filament winding using thermally assisted frontal polymerization (FP). An infrared (IR) heating system is integrated into the winding setup to initiate the FP of a dicyclopentadiene (DCPD)-based resin system to enable composite curing within minutes, directly on the winding machine. The effects of key processing parameters, including the IR input power and rotational speed of mandrel, on temperature evolution and cure behavior are investigated through a combination of thermal profiling experiments and multiphysics simulations. We demonstrate that incorporating a preheating step during winding increases the initial resin temperature and enhances reactivity, leading to more uniform and complete through-thickness curing compared to cases without preheating. This approach is further validated by fabricating a thick composite part (∼1 cm) to demonstrate the scalability of the process through integrated preheating and controlled FP initiation. The results of this study establish practical processing windows for effective, uniform frontal curing in filament-wound composites and offer a pathway toward scalable, rapid composite manufacturing via the filament winding process.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"59 ","pages":"Article 102585"},"PeriodicalIF":7.7,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145060382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While early studies emphasize the importance of controlling ladder–filler interactions, the role of the hybrid interface on interfacial thermal resistance and TC remains underexplored. To address this gap, novel photocurable NCs were developed by incorporating Al₂O₃ nanoparticles (NPs) functionalized with methacrylate (MA) or amino (AA) groups into LPSQs bearing methacrylate and phenyl side chains. Characterizations revealed that methacrylate conversion and crosslinking significantly affect TC. Furthermore, the nature of covalent and non-covalent interactions at the ladder-filler interface influences both LPSQs structural organization and NCs thermal behavior. Among unfilled matrices, methacrylate-rich polysilsesquioxane (LPMASQ) displays the highest TC due to effective crosslinking. MAPSQ(46), with a 40/60 methacrylate-to-phenyl ratio, shows slightly lower TC, where reduced polymerization was offset by π-π stacking that promotes heat transfer. The introduction of MA NPs improves TC in all systems, particularly in LPMASQ, where copolymerization with the matrix reduces interfacial thermal resistance. Conversely, AA NPs, with lower dispersibility and weaker interactions, affect chain organization in LPMASQ, introducing phonon scattering and lowering TC. However, in mixed LPSQs like MAPSQ(64), with a 60/40 methacrylate-to-phenyl ratio, amino groups enhance thermal diffusivity, suggesting that weak interactions can be beneficial in matrices with limited polymerization. These results underscore the critical role of tuning both LPSQs side chain composition and NPs surface functionalization to balance interfacial interactions and maximize thermal performance in polymer NCs for advanced thermal management applications.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"59 ","pages":"Article 102581"},"PeriodicalIF":7.7,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145105102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research indicates that the interface layer is primarily consists of α₂-Ti₃Al phase and β-Ti phase, which have a lower hardness than the two base alloys. The fracture behavior demonstrates that the composite will undergo interface delamination when it expands to the interface layer, which can deflect the main crack and increase the energy release rate, delaying the fracture of the composite. High mechanical stress and soft interfaces are favorable for the occurrence of interface delamination. Simultaneously, the activation of &lt;c+a&gt; dislocations in α₂-Ti₃Al within the interface layer, along with the high accumulation of geometrically necessary dislocations (GND) after fracture, indicates that the interface layer can participate in plastic deformation and coordinate the deformation of the two base alloys.
