In this paper, a novel synergistic multi-scale modeling approach is proposed to predict the progressive failure of two-dimensional triaxially braided composites. A theoretical-based multi-scale model is integrated with finite element calculation in the user subroutine, <em>VUMAT</em>. The developed multi-scale model enables real-time two-way coupled interactions for mechanical response and damage behavior at meso- and macro-scales, and it shows great computational efficiency and generality because of the theoretical nature of the multi-scale computational framework. The proposed framework is utilized to predict the mechanical responses and failure behaviors of different types of specimens: straight-sided, tube, and notched specimens. The predictions show good agreement with both the meso-scale finite element simulations and the experimental results, while reducing the computational time by more than 10 times as compared to the meso-scale model. The theoretical-numerical integrated multi-scale model provides a fast and reliable solution for modeling the progressive failure behavior of textile composite structures under various loading conditions.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"271 ","pages":"Article 111341"},"PeriodicalIF":9.8,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144879891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Winding tension affects resin flow, porosity formation, fiber alignment, and ultimately the mechanical performance of the composite product. This study investigates the effects of winding tension on the structural integrity of carbon fiber-reinforced polymer composites and identifies the root causes of performance variations. A multiscale approach combining analytical, numerical, and experimental methods is employed. Analytical models describe the relationships between winding tension, resin flow, void growth, residual stress, and fiber bed compaction. Numerical simulations using representative volume element capture the microstructural effects of tension on fiber misalignment (with even a 7.12° fiber misalignment can reduce tensile strength by up to 20 %) and porosity, as well as their influence on stress distribution and overall mechanical behavior. Experimental investigations, including quasi-static tensile testing, X-ray tomography, optical microscopy, and fractography, are conducted to validate the models and examine damage mechanisms. The results reveal that increasing winding tension up to 25 N improves fiber alignment and reduces porosity, thereby enhancing the strength of composite. However, tensions beyond this level lead to higher residual stresses and lower mechanical performance due to fiber damage and incomplete resin infiltration. The study identifies 25 N as the optimal additional winding tension, achieving a porosity of 5.54 % with improved structural performance. These findings contribute to better understanding of process–structure relationships and provide guidance for optimizing the manufacturing of high-performance filament-wound composite structures, such as composite pressure vessels.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"271 ","pages":"Article 111340"},"PeriodicalIF":9.8,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This methodology enables visualization of the fracture process zone (FPZ) and quantitative assessment of interfacial damage evolution. To validate the approach, hybrid joints consisting of short-fiber CFRTP (sCFRTP), continuous-fiber CFRTP (cCFRTP), and 64Ti substrates were fabricated using a modified fused filament fabrication process. A polyimide film was inserted between the sCFRTP and 64Ti substrate to introduce an artificial precrack, which promoted stress localization during lap-shear testing. The joints demonstrated a maximum shear strength of 22.3 ± 0.3 MPa, with fractographic analysis revealing cohesive failure within the sCFRTP layer. These results suggest that the primary bonding mechanism is mechanical interlocking due to melt infiltration into the sandblasted titanium surface. The two-scale simulation revealed an FPZ extending approximately 27 μm along the interface, in agreement with the observed fracture morphology near the precrack tip.

This study investigates the interfacial structure, dynamics, and mechanical properties of MMMs using molecular dynamics (MD) simulations. Models were developed by incorporating polyethylene glycol (PEG), polyvinylidene fluoride (PVDF), poly(methyl methacrylate) (PMMA), and polystyrene (PS) into optimized slabs of UiO-66, ZIF-8, and ZIF-90. While PEG and PVDF are known for their high compatibility with MOFs due to strong surface coverage, the rigid PS typically exhibits poor surface coverage. However, our findings reveal an intriguing exception: PS enhances the mechanical stability of ZIF-8 membranes through geometry interlocking at the interface, driven by interfacial dynamics. This behavior contrasts with PVDF, where mechanical stability is not significantly improved. These results emphasize that beyond surface coverage, the geometrical fit and interfacial dynamics are critical factors influencing membranes performance. We further evaluated the impact of polymer content by doubling the polymer layer thickness, which maintained stable Young’s modulus and tensile strength while enhancing failure strain.

Hence, we designed ZnO/Ti₃C₂T_x MXene heterostructured nanofillers by loading surface-modified ZnO nanoparticles onto large-sized Ti₃C₂T_x MXene nanolayers using electrostatic interactions. Subsequently, PVDF/ZnO/Ti₃C₂T_x MXene (PZM) composites were prepared by blending and hot-press molding process with polyvinylidene difluoride (PVDF) resin. By optimizing the doping ratio of ZnO to Ti₃C₂T_x MXene in heterogeneous interface engineering, the high-frequency microwave absorption and thermal conductivity of the composites were precisely tuned. When the mass ratio of ZnO to Ti₃C₂T_x MXene is 3:2 (PZM-3), PZM shows the best attenuation of electromagnetic waves, with a minimum reflection loss of −47.2 dB at a thickness of only 2.5 mm, and an effective absorption bandwidth of 4.2 GHz (11.12–15.32 GHz). This bandwidth covers almost all operating band of high-frequency microwave communication equipment up to 18 GHz. Meanwhile, its thermal conductivity increases by 120 % compared to pristine PVDF resin. Most surprisingly, when the mass ratio of ZnO to Ti₃C₂T_x MXene is 2:3 (PZM-4), the PZM composites exhibit the best thermal conductivity, which increases by 555 %. Furthermore, radar cross section (RCS) was used to simulate the EMW absorption characteristics of PZM composites in practical application scenarios, confirming that PZM composites have a strong EMW loss capability.
