In this study, experiments combined with finite element analysis (FEA) were used to investigate the damage mechanism of transverse low-velocity impacts on three-dimensional woven tubular composites (3DWTC) with different structures. The damage morphology after impact was observed using three-dimensional microscopy and scanning electron microscopy (SEM). Three meso-scale models were constructed based on the authentic structure of the 3DWTC. Additionally, the effects of the structure type on the impact resistance, stress distribution, and damage morphology of 3DWTC were studied. The findings of the study indicate that the shallow cross-linked (SCL) structure exhibits the greatest impact resistance. The through orthogonal (TO) structure exhibits the lowest impact resistance. The greater the straightness of the warp yarns in the structure, the density of the weft, the volume fraction, the greater the cooperative load-bearing capacity of the warp and weft yarns, and the greater the speed of stress propagation. The weft and inner warp yarns are subjected to tensile forces at the point of impact. The outer warp is subjected to compression. The stresses are distributed in a cross-shaped pattern. The straightened warp and weft parts of the TO play an important structural role in load-bearing. The warp yarns of the SCL and the shallow-crossed curved joint (SCCJ) structure play a significant role in the load-bearing capacity of the structure. © 2024, The Authors. All rights reserved.

Pushing the thickness of two-dimensional (2D) metal films to below 10 nm means higher transparency and better flexibility, which will help improve the response sensitivity of flexible electronic devices based on 2D metals. However, lattice distortion and void cracks are facile occurred in the 2D metal film due to the island structure growth mechanism on the traditional solid substrates, which greatly weakens the transparency and conductivity of ultra-thin 2D metal films. Here, we innovatively proposed an air–liquid interface deposition (ALID) method to address this dilemma, in which ultrathin 2D metal films with continuous conductivity were deposited on liquid substrates. Thanks to the shallow injection and the Brownian motion of the liquid substrate, 2D metal (Au, Ag, Cu, Bi, Pt, etc.) films with dimensions up to φ 90 mm × 3.5 nm were obtained through the above method with continuous conductivity in only 5 s. More importantly, compared with the metal film prepared by traditional air–solid interface deposition method, the metal film prepared through ALID has lower surface roughness (0.207 nm), better transparency (85 %), and stronger wear resistance since metal atoms can be arranged almost freely on the isotropic liquid surface. Furthermore, the fabricated resistance sensor based on these 2D metal films can realize flexible sensing such as bending, hitting and stretching motions with ultrafast response time (t = 60 ms) and robust response sensitivity (R/R0 = 800 %). On the one hand, it provides a new solution for the large scale preparation of ultra-thin continuous conductive films, and on the other hand, it enriches the growth mechanism of thin films on the liquid surface. © 2025 Elsevier Ltd

The pursuit of biomimetic fibers with simultaneous high toughness and strength persists, despite their inherent ***, for artificial spider silk based on gel fiber, it is still unclear for the molecular chain attributes related to the improvement of the strength and toughness. Here, a hydrogel fiber was prepared by mimicking the molecular structure of natural spider silk, and we delved into the molecular chain structure characteristics related to the strength, toughness and damping capacity of gel fiber, such as crosslinking density, molecular chain orientation and hydrogen bond interaction. The results indicate that a certain increase in crosslinking density and molecular chain orientation contributes to the enhancement of tensile strength, while the toughness and damping remain essentially unaltered. The thermal dissociation of hydrogen bond could enhance the toughness in a specific range, while the humidity destruction of hydrogen bond would reduce the *** well-regulation control of the weight ratio of polyacrylamide （PAM） to poly（acrylic acid）(PAA), the PAM@PAA gel fibers could reach maximum breaking strength of 1.02 GPa, maximum toughness of 149 MJ m-3, and damping capacity of 95%.PAM@PAA gel fiber has demonstrated excellent wound healing performance and biocompatibility in vivo evaluation as a surgical suture, which indicates its potential in biomedical applications.
