These characteristics, in turn, determine the composite's macroscale mechanical performance. In carbon fiber-reinforced low-melt polyaryletherketone (LM-PAEK™) composites, the influence of processing conditions was systematically examined by producing three distinct sample types through automated fiber placement and post-processing: (1) fast cooling followed by cold crystallization, (2) controlled cooling from melt at 2 °C/min, and (3) fast cooling at rates exceeding 10,000 °C/min. Interfacial mechanical properties and interphase size were characterized using cyclic nanoindentation push-out tests and force-modulation atomic force microscopy, revealing that specimens cooled at 2 °C/min exhibit an interphase region approximately three times thicker than that of rapidly cooled specimens, with enhanced interfacial fiber–matrix strength and fracture toughness. These findings highlight the importance of controlling the interphase thickness in thermoplastic composites.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"299 ","pages":"Article 112444"},"PeriodicalIF":12.7,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725956","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}

A high Zr/Si containing near-α titanium alloy is developed by decreasing-temperature multidirectional forging (DMDF) and subsequent heat treatment, yielding a trimodal microstructure consisting of lamellar primary α-phase (α_l), equiaxed primary α-phase (α_e) and transformed β-phase (β_t). This microstructure features a hierarchical dispersion of dual-scale silicides, where submicron-scale silicides are preferentially distributed along grain/phase boundaries, while nanoscale silicides are uniformly dispersed within grains. After DMDF followed by solution treatment at 950 °C/40min (HT2), the alloy achieves superior room-temperature mechanical properties (UTS = 1306.6 MPa, EL = 7.5 %), primarily attributed to synergistic strengthening effects involving multiscale precipitates (α_S and dual-scale silicides), dislocation networks and activated slip systems. The alloy maintains excellent strength at elevated temperature up to 650 °C, demonstrating a UTS of 799.8 MPa paired with an elongation of 16.2 %. This sustained strength originates from strain gradient formation at α/β interfaces combined with dual-scale silicides pinning mechanisms. Additionally, the enhanced ductility at 650 °C arises from the slip bands within the α-phase and additional &lt;c+a&gt; dislocation activation.

However, the energy absorption performance of these STF related materials is not fully exploited due to the low coupling efficiency between the STF and the structure. In this paper, the dynamic compressive behavior of STF filled star-shaped honeycombs (SSH) with significant negative Poisson's ratio (NPR) effect was studied using modified SHPB experiments and finite element (FE) simulations. The coupling mechanism between the NPR effect and the shear-thickening behavior of STF is analyzed. The dynamic mechanical performance of the STF-filled SSH (SSH-STF) under initial velocity impact and constant velocity compression loading, including stress distribution, energy dissipation, and coupling strength, is comprehensively analyzed. The results indicate that SSH-STF enhances energy absorption efficiency by the mutual extrusion effect of SSH and STF, which limits local deformation and modifies the unstable deformation mode of SSH, while also expanding the energy absorption region. The shear thickening effect of STF limits 82 % of the in-plane rotation behavior of SSH-STF unit cells compared to unfilled SSH under high-velocity impact, promoting uniform and sufficient contraction deformation across the unit cells, which enhances the mean crushing force by 253 %. Meanwhile, the shear thickening behavior of STF leads to faster stress transfer within SSH, significant enhancement of the local deformation stability and effectively increasing the critical impact velocity of the SSH-STF. In this paper, the significant enhancement of energy absorption performance of the STF-SSH composite provides valuable insights for the design of STF-filled auxetic honeycomb structures in practical applications.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"299 ","pages":"Article 112415"},"PeriodicalIF":12.7,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685515","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}

In this study, we propose SUM-1(Zr), a two-dimensional layered MOF that effectively captures C₂H₂ molecules by utilizing electronegative oxygen as hydrogen bond donors and separates C₂H₂/CO₂ mixtures by competitive adsorption between C₂H₂ and CO₂ molecules. The adsorption capacity of SUM-1(Zr) for C₂H₂ was measured to be 3.07 mmol g⁻¹ at 298 K and 1 bar, with an IAST selectivity for C₂H₂/CO₂ reaching 3.33. Kinetic studies demonstrated faster diffusion rates of C₂H₂ and CO₂ molecules in hexagonal channels with larger pore sizes. The electronegative oxygen atoms and –NH molecules in SUM-1(Zr) create a favorable adsorption environment for the guest molecules, while the –NH moiety in SUM-1(Zr) is oriented towards the narrow triangular channels, and the wide hexagonal channels contains numerous electronegative oxygen atoms that act as hydrogen bond donors, selectively trapping C₂H₂ molecules. Theoretical calculations indicate that C₂H₂ prefers to adsorb near the oxygen atoms in the wide hexagonal channels, forming multiple hydrogen bonds with the oxygen atoms in the two adjacent parallel layers. It is worth noting that the binding energies of these two types of channels for C₂H₂ are significantly higher than those for CO₂, resulting in competitive adsorption between C₂H₂ and CO₂.
