Flax bundles exhibit the same non-linear behaviour under mechanical stress as elementary fibres. Video recorded tests revealed that during tensile loading, fibre bundles undergo a coupling between tension and rotation. Three different scenarios were identified: pure tension, tension-torsion coupling to failure, and partial tension-torsion coupling ending before specimen failure. Elementary fibre decohesion was also observed during fibre bundle tensile tests. Overall, the tensile behaviour of fibre bundles is influenced by their initial morphology, especially the degree of twist, and the mechanical efficiency of the lamella between the elementary fibres (middle lamella). In addition, the influence of the geometric model used to represent the cross-section on the mechanical properties was investigated using circular and elliptical models. The results show a significant dependence on the geometrical model considered. Therefore, a standardised method for measuring the cross-sectional area of plant fibres is required to enable comparison of results from the literature.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"308 ","pages":"Article 112955"},"PeriodicalIF":14.2,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004807","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 influence of PVA fiber orientation on ECC's strain hardening and failure process was analyzed, and stress-strain models were developed for different casting methods and fiber contents. The internal energy evolution was analyzed, and fiber orientation was quantitatively assessed using image analysis and CT measurements. Pore characteristics of ECC were evaluated through MIP and CT 3D reconstruction. Oriented samples showed higher tensile strain in the strain hardening stage, with the tensile strain of O2 increasing from 3.92 % in R2 to 5.18 %, compared to randomly cast specimens. Directed casting significantly improved compressive strength, energy release rate, and dissipation capacity, enhancing the tensile performance, elastic strain energy, and fracture energy of ECC. The stress-strain relationship model demonstrated a strong correlation, offering valuable insight for optimizing and applying ECC's performance in engineering. Furthermore, the fluorescent immersion method showed that the fiber inclination angles of oriented casting samples ranged from 20° to 40°, with an orientation factor of 0.85, compared to below 0.75 for randomly cast samples. CT scans confirmed that PVA fibers in oriented casting aligned with the tensile direction, significantly increasing in quantity. MIP analysis revealed that most PVA-ECC pores were smaller than 100 nm, primarily in gel and transition pores, with higher sphericity and more regular shapes.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"308 ","pages":"Article 112967"},"PeriodicalIF":14.2,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144922701","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}

Against this background, extensive research has been conducted on the durability of FRP bars at both material and component levels, aiming to promote the application of this high-performance structural material. This paper presents a comprehensive review on the accelerated aging tests (AAT) related to FRP bars, FRP bar-concrete bonded joints and FRP-reinforced concrete beams subjected to various environmental conditions (e.g., solution immersion, wet-dry cycles, freeze-thaw cycles, high temperature, UV radiation) and/or loading conditions (i.e., with and without sustained loads). Critical parameters influencing the durability issues are extensively discussed based on three databases that were collected by the authors containing over 15,200 test specimens. The findings indicated that the mechanical properties of FRP bars were particularly sensitive to direct solution immersion. A significant dispersion in the test results for bond strength, closely related to bar surface treatment, was observed compared to other mechanical properties of FRP bars. The coupled actions of environmental conditioning and sustained loading were found to have a significantly detrimental impact on the tensile strength of FRP bars, while sustained load tended to reduce the load capacity and overall behavior of FRP-reinforced concrete beams, regardless of exposure conditions.

Therefore, dispersing GNP in water-based elastomers (WBE) such as WPU was one of the problems addressed in this work by employing a novel water-bath technology. In addition, WCL was synergistically employed with GNP for the first time as a reinforcement in WPU. The research presents robust enhancement in mechanical properties realised through thorough static and dynamic mechanical analysis. With GNP/WPU and GNP/WPU/WCL nanocomposites achieving ∼13–25 % and ∼2.5–fold enhancement in modulus respectively across loadings of 0.05–1 wt% at low-strain, which is extremely crucial for high-performing elastomers. Interestingly, the effective toughening in mechanical properties achieved via GNP-alone was realised without loss in elongation, contrary to the result obtained for WCL-infused nanocomposites. As the unfunctionalised GNP showed only a slight crosslinking effect, in contrast to the huge crosslinking observed for the WCL-infused nanocomposites. Hence, the GNP-alone reinforced nanocomposites appear to offer effective recycling potential over those of WCL-infused nanocomposites, which is highly desirable for sustainable industrial applications.

During melt crystallization, spherulite-shaped homocrystals form in the 50/50 PLLA/PDLA phase leading to a primary segregated structure with the MWNT nanoparticles localized in the PLA phase. The generated homocrystals are then reformed into stereocomplex crystals upon annealing at elevated temperatures. Thus, a refined segregation of the MWNTs is achieved forming a conductive pathway via enhanced volume exclusion. The SC crystals formed through melting and recrystallization of homocrystals at a high temperature, where there is enough chain mobility, can effectively compact the segregated network which enhances the electrical conductivity and electromagnetic shielding performance. As a consequence, the electromagnetic shielding effectiveness of this sample is double that of samples re-crystallized at a lower crystallization temperature.
