Abstract Sizing treatment stands out as an indispensable part of actual carbon fiber reinforced polyether ether ketone (CF/PEEK) production for its simple operation and distinct enhancement effects, the recently reported novel waterborne self‐cross‐linkable PEEK derivative sizing agents have achieved tremendous attentions bolstering interfacial bonding CF/PEEK. Nevertheless, key polymer‐precursors utilized in related researches to date are majority rely on petroleum‐based reagents prepared through cumbersome toxic catalytic systems, which become a bottleneck future developments. In this research, sustainable‐minded approach was performed utilizing fully biogenic‐sourced materials. Specifically, magnolol 2,5‐furandicarboxylic‐acid derived 2,5‐bis(4‐fluorobenzoyl)‐furan were elaborate MB‐PEEK. Notably, incorporation CaO catalyst, possessing excellent water absorption properties, allowed eliminating highly azeotropic solvent, thereby achieving green synthetic process. The fastidiously designed full‐bio‐based MB‐PEEK agent conspicuously boosted performances Noteworthy, inherent mechanism during processing stage CF‐(MB‐PEEK)/PEEK encompass self‐crosslinking allyl groups toward stable crosslinked structures with unparalleled resistance solvents unorthodox robustness interphase. Among them, interlaminar shear strength sized‐CF/PEEK improved by 65.71% 55.09%. even after enduring 3 days solvent aging, mechanical integrity preserved at approximately 93%. Our study presents straightforward sustainable outstanding properties that show effect performance solvent‐resistance Highlights A cross‐linkable CF/PEEK prepared. Magnolol 2,5‐furandicarboxylic acid employed substituted reagent. catalyst used replace poisonous systems. ILSS, IFSS, bending significantly increased 55.09%, 65.71%, 34.14%. Treated composites remained over 93% week corrosion.

Abstract This study reveals the impact resistance of shear thickening gel (STG) impregnated four‐layer regular angle interlocking fabrics (AIF) composites. The effects STG parameters, including reaction time, temperature, and ratio, on rheological characterization mechanical properties STG/AIF flexible composites were investigated. results show that increase in parameters accelerated formation BO crosslink bonds within STG. energy storage modulus increased by three orders magnitude for a temperature 230°C, time 9 h, ratio 12.5%. had an obvious effect. coupling effect AIF increases inter‐yarn friction. deformation fabric synergistically absorbed energy, absorption rate reached 95.6%. material surface was not significantly damaged after low‐velocity impact. showed excellent properties. Highlights A new high‐energy composite prepared. Increased promoted its internal reaction. B O atomic interactions enhance improve resistance.

The organic-inorganic interfacial nanostructures between fillers and the matrix play a crucial role in performance of polymer composites. Here we propose an situ cryogenic transmission electron microscope technique (cryo-TEM) approach to directly observe transformation toluene diisocyanate (TDI)-based polyurethane composite during its synthesis process. Elliptical protrusions growing radially outward from filler surface, which serve as critical intermediate interface layer, are observed by cryo-TEM, indicating that layer is formed through curing reaction prepolymer molecules anchored on surface. Both decreasing sizes adding coupling agents can enhance interactions. addition 0.05 wt % agent increases thickness 83.93 129.31 nm improves fracture toughness 75.1%. These findings provide new insights for rationally designing high-performance

Abstract To address the utilization needs of composites under unconventional lubrication conditions, this paper conducted a mixture design experiment utilizing m‐polyphthalazine ether sulfone ketone (m‐PPESK) as resin matrix, along with short‐cut carbon fibers (SCF), polytetrafluoroethylene (PTFE), and graphite (Gr) modified fillers. The mathematical models between each response value (including compressive strength, tensile strength (TS), coefficient friction dry water conditions [ μ ]) filler contents were constructed. impact fillers their synergistic interactions on properties was systematically studied. Combined multi‐objective optimization method, optimal formula m‐PPESK composite determined 70 wt% resin, 9 SCF, 10 PTFE, 11 Gr. Compared to pure optimized demonstrated 25.4% increase in TS, alongside 56.4% 55.9% reduction , respectively. Scanning electron microscopy energy dispersive spectroscopy analyses indicated that multicomponent could synergistically facilitate formation transfer film, thus improving tribological composites. Highlights High‐strength, low‐friction water‐lubricated prepared. increased by 25.4%. reduced 55.9%. regression equations obtained had good predictability. Gr effects properties.
