In this article, the slender 316L stainless steel tube was first ground by magnetorheological fluid and then coated with the slurry, which can not only increase the contact area between the coating and the substrate but also prevent the generation of new substances that have adversely affected the adhesion of the coating. The properties of the samples were characterized and analyzed; the results showed that the substrate ground by magnetorheological fluid is more favorable for bonding with coating under the grinding conditions that the speed of the tube is 210 rpm, magnetic induction intensity is 40.83 mT, and mass ratio of micron and submicron magnetic particles is 2.3. The coating prepared under the above conditions has uniform thickness, flat surface, and can better inhibit the diffusion of Cr of the substrate to its surface. It can be obtained from corrosion resistance analysis that the coating has the highest self-corrosion potential of −0.016 V and the lowest corrosion current density of 0.491 μA/cm2, which indicate that the coating has the strongest corrosion resistance. According to the composition analysis of the coating, the composition of the corroded coating is similar to that of the coating itself, but accompanied by a small amount of Fe, which indirectly indicates that the coating is relatively compact, the coating is well bonded with the substrate, and the coating can protect the substrate; thus, the service life of 316L stainless steel instrumentation tubes is extended.","PeriodicalId":21480,"journal":{"name":"Science and Engineering of Composite Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45164937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to study the influence of high-frequency vibratory mixing on the performance of concrete more accurately, ordinary concrete C40, C50 steel fiber concrete, and C60 high-strength concrete are selected to make reach experiments in the article. After determining the optimum mixing ratio, the contrast experiment on forced mixing and high-frequency vibratory mixing (which at a given frequency) was operated first, which is for studying the improvement of workability and mechanical properties of concrete by vibratory mixing and then exploring the change of concrete performance under different vibration frequency in slump test, compressive strength test, and freeze–thaw test. The results indicate that compared with forced mixing, the compressive strength and splitting tensile strength of concrete all have been proposed in different ages (3 days, 7 days, and 28 days) with vibratory concrete mixing, and C50 steel fiber concrete has the highest compressive strength improvement rate. There is a deviation in the mechanism of concrete in different ages, which is affected by high-frequency vibration. But in the context of the whole test, high-frequency vibratory mixing is helpful for the working properties, mechanical properties, and durability of the concrete. Within the scope of the frequency values in the test, the best vibration frequency for C40 ordinary concrete is 190 Hz, and in 212 Hz, C50 steel fiber concrete and C60 high-frequency concrete present the best performance.","PeriodicalId":21480,"journal":{"name":"Science and Engineering of Composite Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47130741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the flexural damage behaviors of CFRP composites by using a combination of acoustic emission (AE) and X-ray micro-computed tomography (micro-CT). Four specimens with different delamination defects and 0.1 wt% cellulose nanofibers (CNFs) were subjected to three-point bending tests. AE was employed to monitor the loading process, and then, micro-CT was utilized to detect the internal damage. The results showed that for the specimens with preset delamination defects near the surface, CNF-reinforced specimen exhibited no obvious enhancement effect on bending strength, and its cumulative acoustic energy decreased by 28% compared with that of CFRP specimens. For the specimen with preset delamination damage in the middle position, CNFs had an obvious enhancement effect on mechanical behavior, and the cumulative acoustic energy decreased by 43%. No obvious kink band was observed in the CNF-reinforced specimens, and during crack propagation, causing cracking and delamination damage was difficult. The results of micro-CT are consistent with those of AE. The results combined the combination of AE and micro-CT reflect the superiority of the hybrid detection system.","PeriodicalId":21480,"journal":{"name":"Science and Engineering of Composite Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42367051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the serviceability of concrete structures has been significantly reduced owing to a variety of durability issues, especially when serving in a non-ideal environment and exposed to internal/external attacks such as chloride penetration, carbonation, sulfate, and so on. Several scholars have performed numerous studies on the strength and microstructure features of volcanic ash (VA) concrete and have discovered encouraging findings. However, since the information is spread, readers find it difficult to evaluate the benefits of VA-based concrete, limiting its applicability. As a result, a detailed study is required that offers the reader an easy approach and highlights all essential facts. The goal of this article (Part Ц) is to conduct a compressive review of the physical and chemical aspects of VA and its impact on concrete durability and microstructure properties. The findings demonstrate that VA considerably improves concrete durability owing to pozzolanic reaction and micro-filling voids in concrete materials. Cost–benefit analysis shows that 10% utilization of VA as cement decreased the overall cost by 30%. The assessment also notes a research gap that must be filled before VA may be utilized in practice.","PeriodicalId":21480,"journal":{"name":"Science and Engineering of Composite Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43088736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emerging capsule-based self-healing system provides a new strategy for repairing the cracks, effectively delaying the potential damage of the matrix, and prolonging the service life of composite materials. Determining the optimal size and dosage of microcapsules required to repair cracks in the matrix is essential for the development and design of capsule-based self-healing materials. This paper presents a novel two-dimensional capsule-based self-healing model composite material whose surface is paved by reproducible and random cells and some microcapsules are randomly dispersed in those cells to investigate the rupture behavior of microcapsules forced by growing cracks. An analytical model is proposed from the viewpoint of geometrical probability to express the probability characteristics of the embedded microcapsules stimulated by linear cracks in a two-dimensional capsule-based self-healing model composite. Additionally, the effect of the size and dosage of the embedded microcapsules on the intersection probability is analyzed, and the maximal probability is also found to improve the self-healing efficiency. Finally, the accuracies of these probability values and theoretical solutions are verified via computer simulation, and the results show that the developed model of the geometrical probability of the crack intersection with microcapsules randomly distributed in the cells of the matrix will help to provide a theoretical basis for the quantitative design of capsule-based self-healing materials.","PeriodicalId":21480,"journal":{"name":"Science and Engineering of Composite Materials","volume":"30 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67051194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
