Mechanochromism, which implies that a material can change color in response to mechanical stimulation, could be a potential tool to solve this problem. However, researches on mechanochromic polymers have primarily focused on elastomers and gels. For rigid epoxy thermosets, it is still difficult to achieve significant mechanochromism, let alone multicolor changes under different mechanical stimuli. In this study, SiO₂ nanoparticles (NPs) are introduced into a rhodamine (Rh)-modified epoxy system to improve its mechanochromic response. When the nanocomposite is mechanically stimulated, concentrated stress around the heterogeneous interfaces induces massive ring-opening reactions of Rh in these areas, resulting in a vivid red color change. In addition, direct observation of the stress-concentration effect near the rigid particles is realized by using the visualization properties of the Rh moiety, and combined with finite element analysis to elucidate the enhancement mechanism of the mechanochromism. Furthermore, how the NPs affect multicolor mechanochromism of epoxy thermosets is also investigated. Nanocomposites with two different mechanochromophores exhibit stress- and time-dependent five-color variations due to the different activation of the Rh and disulfide moieties, whereas samples without NPs only show a triple-color change with lower contrast. This strategy is suitable for use in practical applications owning to its ability to display the stress intensity and stress history of a material through high-contrast multicolor switching. Several proof-of-concept scenarios are presented.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"267 ","pages":"Article 111184"},"PeriodicalIF":8.3,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the high linearity and wide sensing range of strain sensors are difficult to achieve. Herein, a flexible strain/temperature sensor (FSTS) is developed based on arch-inspired bionic structure and multi-walled carbon nanotubes/carbon black/polyaniline/silicone rubber nanocomposites. The prepared FSTS has both strain and temperature sensing capabilities. It functions as a FSTS with a high sensitivity of 3.432 and an ultra-low lower limit of detection (0.1 % strain). The wide linear detection range (0–190 % strain range) and ultra-high linearity (0.996) are realized simultaneously. These properties are attributed to arch-like fingerprint structure and multi-dimensional mixed materials. In addition, the designed FSTS has a resistive temperature coefficient of up to 57.301, a linearity of 0.999 over an ultra-wide temperature range (25–120 °C), and fine repeatability. Due to its improved sensing capabilities, FSTS can be applied to recognize sign language movements and intelligently temperature monitoring.

This research introduces a comprehensive framework using transfer learning that combines data from a mean-field homogenization approach with high-fidelity full-field simulations. In a design space characterized by diverse loading conditions and micro-scale constitutive material properties, the goal is to address the challenges of generating sufficient datasets for training a data-hungry gated recurrent neural network (GRU). Multiple datasets of varying precision are generated and used, containing multi-axial stress–strain responses under two load types: random walking and proportional cyclic loading. Moreover, this study emphasizes the importance of temporal correlations in the dataset, which align with the physically path-dependent behavior of most non-linear materials, and demonstrates that temporal correlations are crucial for training time-series models. These correlations also provide the foundation for data augmentation using a linear interpolation technique within time-series stress analyses, enabling accurate predictions of homogenized meso-scale stresses based on strain trajectories and microstructural properties. Results demonstrate that integrating transfer learning with neural networks successfully incorporates a limited number of high-fidelity data with more accessible but low-fidelity data.

To overcome these limitations, a carbon nanotube (CNT)-based omnidirectional sensing system was developed as a structurally integrated nanocomposite surfacing layer for composite structures. This novel sensor system enables the detection of strain in all directions using a single nanocomposite sensor, while simultaneously measuring temperature to isolate its effects. Experimental results demonstrated that the sensor accurately measured the full in-plane strain tensor under tensile loading, closely aligning with reference data from a 3-element strain gauge rosette. It also exhibited high temperature accuracy, with a maximum error of 0.3%.
