However, carbon fiber's chemical inertness results in weak interactions with the polymer matrix, which hinders the overall performance of the composites. Improving the interfacial properties has been a longstanding challenge in CFRPs development. Introducing nanomaterials along with chemical agents at the interface can enhance both physical and chemical interactions, facilitating better load transfer and more uniform stress distribution. Despite this, surface modification remains a complex process, and the lack of anchor bonds limits the effectiveness of chemical interactions. In this work, inspired by the crack-resistance mechanism of byssal cuticle through metal coordination bonds, we introduce a metal-phenolic network comprising ferric iron (Fe³⁺) and tannic acid (TA) onto the carbon fiber surface using a simple one-pot deposition method. This approach significantly enhances the interfacial properties of the composite. The Fe³⁺-TA complex forms nano-sized aggregates on the fiber surface, with their morphology controllable by adjusting the precursor concentration and pH. The multiple reactive groups on TA allow for the incorporation of a silane coupling agent, effectively creating a chemical bridge between the carbon fiber and the matrix, further improving interfacial properties through synergistic chemical and physical interactions. This metal-phenolic network not only simultaneously strengthens and toughens the interface by promoting mechanical interlocking but also provides multiple chemical anchor sites to bridge the two components, offering new insights into strategies for interfacial strengthening and regulation.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"300 ","pages":"Article 112466"},"PeriodicalIF":12.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746748","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}

The damage evolution mechanism of CFRP laminates under sand erosion is quantitatively analyzed, while residual mechanical performance is also assessed. The experimental results show that continuous sand erosion typically results in erosion pits at the impact center and abrasion bands on the surface of CFRP laminates. It is found that as the erosion velocity increases, both the material strength and stiffness decrease significantly, with peak reductions of 64.7 % in tensile strength and 46.2 % in elastic modulus observed at the maximum tested velocity (200 m/s). An analytical model was developed to characterize the relationship between residual tensile strength and erosion damage parameters, which demonstrates good agreement with experimental results, with an average error below 7 %.

However, the specific electric double layer (EDL) between the Si anode and electrolyte causes severe hydrogen evolution corrosion, resulting in a significant deviation of the specific capacity from its theoretical value. To address this issue, a low-cost and high-efficiency additive strategy was developed. By introducing a small amount of dodecyl dimethyl benzyl ammonium bromide (DDBAB), which features a (C₂H₅)₂N⁺ group that strongly interacts with OH⁻, and a hydrophobic C₁₂H₂₅ and C₂H₅, the EDL is altered and an <em>in-situ</em> hydrophobic protective layer is formed. This layer effectively repels active H₂O from the Si anode/electrolyte interface and increases the barriers to hydrogen evolution reactions (HER). As a result, the hydrogen evolution inhibition efficiency of Si anode reached 99.36 %. The aqueous silicon-air batteries (SABs) lasted from 173 h to 500 h, and the energy density and specific capacity enhanced by 2.6-fold and 2.7-fold, respectively. Due to the temperature-insensitive binding energy between DDBAB and the Si anode, the quasi-solid-state SABs (QSSSABs), using PAAK-M gel electrolyte, as a proof of concept, exhibit a high specific capacity of 324.54 Ah kg⁻¹, excellent stability across a wide temperature range (−10 °C to 60 °C), and great application potential.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"300 ","pages":"Article 112456"},"PeriodicalIF":12.7,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746848","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}

The findings reveal that colloidal particles tend to cluster into either homogeneous or heterogeneous aggregates, mediated by the surrounding liquid. This clustering aids the formation of desired phases during pulsed laser processing. Temperature-dependent thermodynamic phase transitions, combined with pulse-driven heating-cooling dynamics, promote copper oxidation and magnetite reduction, achieving both compositional control and microstructural surface activation.

As both the friction and conductive layers in a triboelectric nanogenerator-based sensor, the composite ionogel's output performance is significantly enhanced by the synergistic effects of Cu(NO₃)₂ and multi-walled carbon nanotubes (MWCNTs), resulting in a 4.23-fold increase in output voltage.

Furthermore, the incorporation of MWCNTs imparts exceptional thermal sensitivity (0.456 % °C⁻¹) to the sensor, allowing accurate real-time body temperature monitoring.

The shock response of SPLTC with different fillers at impact velocities ranging from 50 to 200 m/s is analyzed using FSI simulations. The results show that STF-filled SPLTC (SPLTC-STF) significantly improves shock resistance and energy dissipation, absorbing 1.6 times more energy than the empty SPLTC. Additionally, the effect of STF thickening properties on the shock behavior of SPLTC-STF is analyzed, revealing that higher STF viscosity reduces deformation, enhances energy absorption, and increases buckling resistance. A two-stage energy dissipation process is identified, consisting of the shock wave attenuation stage and the FSI dissipation stage. While the specific energy absorption (SEA) increases with STF viscosity, it decreases beyond a critical viscosity threshold due to reduced fluidity and weaker FSI effects. These findings underscore the potential of SPLTC-STF for impact-protection applications and highlight the importance of optimizing STF parameters for maximum energy absorption.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"299 ","pages":"Article 112449"},"PeriodicalIF":12.7,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725839","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}

PolyJet 3D printing technique is employed to fabricate the studied HLCPR and HLRSM samples with lattice of PR from -0.8 to 0.8, and tensile tests were conducted with the help of DIC method to obtain their mechanical properties and capture the fracture behaviors. Numerical results agree well with the test results in terms of effective Young’s modulus, strength and fracture behaviors. Results show that coupling between the soft matrix and the HLCPR due to deformation mismatch leads to significant enhancement of mechanical properties, and such coupling effect varies with the PR of the HLCPR. The HLCPR of PR -0.8 leads to the strongest coupling effect, while that of PR 0.4 exhibits the weakest. The soft matrix delays fracture initiation in the HLCPR and transforms the fracture mode from sudden rupture to a progressive failure. Results also demonstrate that HLRSM with HLCPR of -0.8 exhibits superior performance compared to that with an uncontrollable PR or breaking hard lattices.
