This approach aimed to enhance transverse strength while addressing size limitations. The obtained transparent bamboo had excellent transparency effect. Furthermore, by optimizing the weaving structure, the anisotropy of transparent bamboo can be adjusted to isotropy, and the absolute error of longitudinal and transverse tensile strength was reduced from 29.9 to 0.7 to obtain homogeneous materials. Finally, the lattice interlocking structure was designed to fabricate a transparent bamboo measuring 2300 mm in length, 530 mm in width, and 1 mm in thickness, which was 66.9 times that of the previously reported transparent bamboo.

In this study, PEEK-based composite filaments filled with nanoscale silicon dioxide (SiO₂) and microscale short carbon fibers (SCF) were successfully fabricated using melt compounding and 3D printing using FFF.

Thermal and structural analysis confirmed that the chemical integrity of the PEEK matrix remained intact during the filament processing and 3D printing. Nano-SiO₂ enhanced the thermal decomposition temperatures and improved the crystallization behavior of SCF-PEEK. Multiscale composites exhibited up to 40 % and 11 % increments in stiffness compared to neat PEEK and SCF-PEEK, respectively.

In this study, interfacial pulley structures were strategically engineered through the development of branched polynaphthalamic acid-based polyrotaxane (BPP), thereby enabling simultaneous enhancement of interfacial toughness and strength in CFRPs. Molecular dynamics simulations combined with comprehensive chemical structure characterization validated the rational molecular design and successful synthesis of BPP. Comparative analysis demonstrated that the BPP-modified carbon fiber/epoxy composites (BPPCF/EP) displayed a substantially increased interphase thickness of 412.50 nm compared to unmodified CF/EP (UCF/EP), along with a gradual modulus transition and a notable 78.15 % decrease in interfacial residual stress. These improvements stem from the synergistic effect of the naphthalimide anchor, which facilitates modulus gradient regulation, and the unique molecular pulley mechanism inherent to the BPP architecture.

Traditional methods, mainly depending on empirical correlations and accelerated aging tests, struggle to generalize across real-world conditions and isolate individual degradation mechanisms, undermining the reliability of their predictions. Machine learning (ML) presents a compelling alternative, with the ability to manage non-linear relationships among numerous variables. Recent advancements in FRP durability testing have produced extensive data, creating opportunities for ML-driven predictive modeling.
