Inspired by plant root structures, titanium pins were fabricated using selective laser melting (SLM) to achieve intricate geometries and enhanced surface roughness for improved interlocking. Pullout testing demonstrated significant improvements in load-bearing capacity and energy dissipation, with −45° branched pin joints showing the highest performance. In these joints, fibres beneath the pin engaged with the branches during pullout, preventing slippage until the branches bent to a positive angle or fractured. Pullout strength increased by 94 % in 90° fibre-oriented laminates (fibres perpendicular to the pin and branch plane), 34 % in 0° laminates (fibres parallel to the plane), and 47 % in 45° laminates (fibres at 45° to the plane), compared to unbranched pins. Overall, branched pins increased pullout strength by 22–94 % depending on fibre orientation, demonstrating the combined effect of branch geometry and laminate anisotropy. Micro-computed tomography (µCT) and scanning electron microscopy (SEM) revealed key failure mechanisms, including branch rupture, fibre pullout, matrix cracking, and composite crushing. These findings highlight the influence of both branch geometry and fibre orientation on joint performance. This bio-inspired approach introduces a new design paradigm for hybrid joints, offering a practical pathway to enhance durability, energy absorption, and structural efficiency in aerospace applications.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"200 ","pages":"Article 109315"},"PeriodicalIF":8.1,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensing layer was fabricated by a bionic template method using Arundo donax leaves as the template in a fast and cost-effective way, in which composites of multi-walled carbon nanotubes (MWCNT) and polydimethylsiloxane (PDMS) were synthesized with excellent flexibility and piezoresistive properties.

The hierarchical ridge-like microstructures with parallel primary ridges and secondary ridges contributed to enhance contact area and deformation capacity, and maintain continuous contact between the sensing layer and electrodes.

Nanocomposites offer an alternative to balance flame retardancy with overall properties. Despite progress with halogen-free systems and graphene-based fillers, challenges remain in achieving uniform dispersion in epoxy and maintaining mechanical integrity at low loadings. These limitations reduce char quality and flame-retardant efficiency under realistic heat flux, highlighting the need for sustainable, ultra-low-dose solutions that deliver UL-94 V-0 and high LOI without sacrificing strength or toughness. In this work, bio-based phytic acid (PA) and tannic acid (TA) dual-modified graphene oxide frameworks (GOFs) were used to prepare multifunctional epoxy nanocomposites. At only 0.75 wt% PA–TA@GOF, the composites achieved an LOI of 30.0 % and UL-94 V-0 rating. Cone calorimetry showed substantial reductions in peak heat release rate (41.2 %), total heat release (13.9 %), and total smoke production (41.6 %) compared with neat epoxy. These improvements arise from the ability of PA–TA@GOF to effectively restrict heat, oxygen, and volatile fuels. Notably, the enhanced fire resistance was achieved without compromising mechanical strength or toughness. This study presents a green, scalable route that simultaneously enhances flame retardancy, mechanical performance, and EMI shielding effectiveness at ultra-low filler loadings.

In this paper, we develop a method to quantify the <em>three–dimensional</em> irradiance envelope for a Xenon-arc flash lamp (XFL) and link that envelope quantitatively to the thermal evolution of Carbon Fiber/Low Melt Polyaryletherketone (CF/LM-PAEK) tape. A robot-mounted Gardon gauge acquired more than 1000 flux measurements that were interpolated with radial-basis function (RBF) to estimate the 3D flux field. A third-order power–scaling law enabled the prediction for multiple lamp power levels. Ex-situ measurements in which the lamp traversed a stationary ten-tow panel at 35–500 mm/s revealed (i) a measurable thermal lag between the moving irradiance peak and the peak surface temperature that widens with speed, (ii) non-unique power–speed pairs able to deliver the same radiant exposure, and (iii) a monotonic but location-sensitive relationship between radiant exposure (0.05–0.15 MJ m⁻²) and peak temperature (<span><math><mrow><mn>240</mn><mo>−</mo><mn>40</mn><msup><mrow><mn>0</mn></mrow><mrow><mo>∘</mo></mrow></msup><mi>C</mi></mrow></math></span>).
