However, conventional polymer matrices used in composite materials exhibit poor oxygen and moisture barrier properties, compromising electrolyte stability. To address this issue, a selective encapsulation strategy was implemented using a liquid thermoplastic polymer and masking techniques. A polypropylene barrier, recognized for its superior moisture and oxygen resistance, was selectively integrated around the electrode regions, while a thermoplastic polymer was applied to the external layers. This advanced design significantly enhanced electrolyte protection. One of the primary challenges in structural battery design is the weak interfacial adhesion between current collectors, electrolyte layers, and separators, which can lead to delamination, increased internal resistance, and reduced charge transfer efficiency. To mitigate these issues, a stitching reinforcement strategy was employed, minimizing electrode spacing between the cathode and anode to optimize ion transport pathways. In a static structural battery, the incorporation of a stitching architecture resulted in up to a 13 % increase in energy density compared to the non-stitched configuration. The stitching architecture effectively maintained a narrow electrode spacing between the cathode and anode under mechanical loads, significantly enhancing capacity retention. The proposed structural battery exhibited a tensile strength of 189 MPa and a tensile modulus of 9.1 GPa, achieving an energy density of up to 39.5 Wh/kg based on the total mass of the structural battery. These findings underscore the substantial potential of stitched structural batteries in high-performance applications, providing an innovative approach to improving both mechanical integrity and electrochemical efficiency in multifunctional energy storage systems.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"303 ","pages":"Article 112583"},"PeriodicalIF":12.7,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900312","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}

Notably, no additional resin was incorporated as a matrix material during this process. The study systematically investigated the influence of reactive dyes and vat dyes on the mechanical properties of the composites before and after decolorization. The results revealed that the mechanical properties of reactive dye-dyed fiber composites (RDFC) were significantly inferior to those of undyed fiber composites (UDFC) and decolorized fiber composites, with reductions ranging from approximately 9.76 %–407.72 %. In contrast, the mechanical properties of vat dye-dyed fiber composites (VDFC) exceeded those of UDFC and decolorized fiber composites, showing improvements between 1.1 % and 29.61 %. Under wet conditions, all types of fiber composites exhibited a mechanical property loss of approximately 20 % after decolorization, indicating that the influence of moisture is manageable. Furthermore, the strength of these composites was found to be comparable to traditional materials such as gypsum boards and logistics wood pallets, among other applications.

Notably, the composite films exhibited exceptional structural stability under 40 keV He ion irradiation compared to their crystalline AlCrFeNi counterpart, which suffered severe lattice damage in the peak irradiation area. The post-irradiation characterization revealed a substantial hardness increase in AlCrFeNi (ΔH = 4.4 GPa), while composite films maintained superior stability with minimal changes (B10: 2.6 GPa; B60: 1.7 GPa). The tribological results showed that for the as-deposited films, the wear rate of the composite films is significantly lower than that of AlCrFeNi films. Molecular dynamics (MD) simulations unveiled that the unique SRO-dominated microstructure could achieve effective shear strain dispersion and enhance the plastic deformation capacity of subsurface. Counterintuitively, the composite films exhibited irradiation-induced wear resistance improvement in wear resistance instead of the degradation of traditional lubricating films. Especially under the high-dose conditions, the wear rate of the B60 films is 5.1 times lower than that of AlCrFeNi films.

The LaRC05 fiber tensile failure criterion was revised based on experimental data, improving the accuracy of the model at higher impact energies.

Impact bending tests based on ISO179-1/2 were performed to assess the mechanical potential of such a novel reinforcement. Two sources of fibre reinforcement were considered for a comparison; glass fibres (E-glass) and high-tenacity viscose filaments. Based on biomimetic considerations, structural features such as yarn twist and a partial impregnation of the yarn were implemented to foster a tough composite failure. A Finite Element (FE) model was proposed to describe the effect of cellulosic reinforcements under dynamic loading, considering the impregnation with different adhesive systems. The results indicated a strong influence of the fibre impregnation. With a mean impact strength of 38.6 kJ/m² cellulose filaments impregnated with epoxy showed only a moderate improvement compared to 34.7 kJ/m² for non-reinforced wood. When impregnated with an emulsion polymer isocyanate, impact strength more than doubled to 88.9 kJ/m². This was traced back to the partial impregnation of the yarn cross-section.
