This study addresses this challenge by employing three-dimensional spacer woven glass fiber fabric (GF-3D-SF) to reinforce both rigid (TEOS-based) and flexible (MTMS-based) silica aerogel matrices. The effects of fabric geometric parameters (spacer density and height) on the microstructure, mechanical properties, and thermal insulation performance of the composites were systematically investigated. Results reveal two distinct reinforcement mechanisms tailored to matrix stiffness. For rigid TEOS-based composites, strong interfacial bonding enables effective stress transfer and fiber bridging, significantly enhancing compressive/flexural strength with increased density. However, higher spacer height induces Euler buckling and thus degrades structural stability. For flexible MTMS-based composites, although weak interfacial bonding limits strength enhancement, the inherent elasticity of the matrix endows the composites with exceptional elastic recovery and cyclic fatigue resistance, which is complemented by the structural support of the 3D spacer fabric. Thermal conductivity increases with spacer density but decreases with spacer height.

The bistable QZS cell comprises hard-magnetic asymmetric beams (positive stiffness) and a bistable buckled beam (negative stiffness). Magnetic actuation deflects the asymmetric beams, triggering the buckled beam to snap between stable upward and downward states.

Therefore, this study investigates the potential of Scholte modes, which are nondamping modes of guided waves, for the nondestructive inspection of underwater CFRP plates. The Rayleigh-Lamb equations for a free plate are generalized, and the governing equations of guided waves are derived for an orthotropic CFRP plate immersed in water. The propagation properties of the excitable Scholte modes are revealed by solving the derived equation. First, it is observed that in the fiber (0°) direction, one symmetric and one anti-symmetric mode are excitable, whereas in the 90° direction that is perpendicular to the fiber, infinitely many modes can be excited. Furthermore, it is shown that, unlike in aluminum, where most power propagates in water at high frequency, a larger portion of power flux is confined within the plate in the CFRP case: approximately 35% in the 0° direction, 72% for the lowest modes in the 90° direction, and nearly 100% for the higher modes in the 90° direction. Owing to the superior confinement of the Scholte mode in CFRP plates, Scholte modes are inferred to be promising for damage detection, such as matrix cracks of the plate. This is in contrast to the case of aluminum, where the higher-frequency Scholte modes are not sensitive to cracks because of the lower confinement of the power within the plate.</div></div>","PeriodicalId":281,"journal":{"name":"Composite Structures","volume":"391 ","pages":"Article 120561"},"PeriodicalIF":7.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148525966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores the acoustoelastic effect on the propagation of Lamb waves in composite laminates. Firstly, a quasi-one-dimensional (1D) finite element (FE) model was developed, incorporating a 14-constant hyperelastic constitutive model, to simulate the acoustoelastic effect on longitudinal bulk waves propagating in transversely isotropic materials. The results were compared with the corresponding theoretical results for validation purposes. Subsequently, the validated FE method was applied to a three-dimensional (3D) FE model to investigate the acoustoelastic effect on the propagation of Lamb waves in unidirectional, bidirectional and quasi-isotropic (QI) CFRP laminates. Both uniaxial and biaxial stress-induced acoustoelastic effects on the propagation of Lamb waves in composite laminates are investigated. Furthermore, a uniaxial tension experiment was conducted to investigate the feasibility of in-situ stress monitoring for composite laminates using Lamb waves. The results indicate that the acoustoelastic effect can be utilised for in-situ stress monitoring in composite laminates.

The present work focuses on the relationship between the clamped length of the specimen and the validity of Linear Elastic Fracture Mechanics (LEFM). For the joint subjected to sliding conditions with a relatively short clamped length, local damage formed close to the clamp, resulting in the invalidity of LEFM. This was due to the absence of sufficient boundary constraints as LEFM became valid again under the scenario of the specimen end being perfectly fixed. Furthermore, the validity of LEFM could be restored by extending the clamped length of the specimen. Additionally, a numerical approximation of the crack length, including the contribution from accumulated microcracks, is proposed to evaluate the equivalent crack length determined by LEFM.
