The key idea of the proposed approach is to insert the anisotropic plate between an eddy current (EC) probe and a test piece for controlling the electromagnetic field. Distribution of the space magnetic field and induced current density was numerically investigated. The simulation results showed that deformation of the magnetic field distribution occurs in the case of inserting an anisotropic plate. Meanwhile, it makes the magnetic field distribution directional and its direction will be changeable and controllable by rotating angle θ of the anisotropic plate. Furthermore, redistribution of the induced current density can be observed in the test piece, which results in two identical peak areas, and they are symmetric with respect to an axis perpendicular to the rotation angle. Subsequently, output voltage of the EC probe was calculated to quantitatively analyze the sensitivity for identifying crack orientation. Findings show that the output voltage from the probe was affected by the angle between the conductivity angle θ of the anisotropic plate and the crack orientation.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":"32 1","pages":"163 - 181"},"PeriodicalIF":2.9,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49078251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past two decades, there has been extensive research on the development of multifunctional fibre reinforced composite structures which can fulfil several secondary functions besides its structural role. As a result, structural energy storage composites have been developing rapidly which can sustain electrochemical energy storage as well as structural load-bearing. Among the many structural energy storage composites, structural supercapacitor composites (structural supercapacitors) have attracted the attention of many researchers. This article provides an up-to-date review on the development of structural supercapacitors, which can be integrated into structural fibre reinforced polymeric components. Specifically, an outline is given of the development of carbon fibre fabric based structural supercapacitors, with the focus on various surface activations for performance improvement. Moreover, the recent development in critical components of structural supercapacitors, such as solid electrolytes and separators, is also highlighted. The limitations and challenges for the development of structural supercapacitors are also incorporated.

The impacts were performed with energies from 18.4 to 59.2 J using a drop-tower apparatus, and a post-mortem analysis after each impact was employed to assess the impact response. A damage index was used to describe the changes in impact response due to repeated impacts. Finite element simulations considering both interlaminar and intralaminar failure modes were performed. The results showed that the impact force and bending stiffness decreased with the number of impacts, while impact duration and maximum central displacement increased. The shape of the damaged area was also affected. The numerical results showed that interlaminar damage initiated at most interfaces during the first impact, followed by in-plane propagation in the next impacts. Also, intralaminar damage initiated at the backside of the laminate, and then in-plane and through-thickness propagations followed until penetration occurred.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":"1 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42000824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest fatigue strengths have been recorded for composites with 0°/90° glass fiber ply orientations. Composite with ±45° alignment has the lowest fatigue strengths in S-N curves. Stiffness degradation of the composites with 0°/90° and 0°/90°/±45° at medium fatigue stress levels was calculated and showed higher degradation for stacking having more off-axis plies, i.e. 0°/90°/±45° alignment. Temperature increase during fatigue testing was measured using an IR camera for a medium fatigue stress level for 0°/90°/±45° alignment. Temperature increases were calculated for all stress amplitudes for composites with 0°/90°/±45° and 0°/90° alignment cross-ply sequences. The temperatures obtained were all below the glass transition temperature of the material.

Although the experimental section in both works were identical, the reported numerical values of the linear buckling loads differed. In addition, all the specimens were manufactured using an identical process by employing silicone rubber mold and filament winding technique, and outer skin layers and stiffeners consisted of a fixed number of plies. Nonetheless, different shell thicknesses and stiffeners cross-sectional areas were reported for the specimens. Since the buckling behavior of cylindrical shells is highly sensitive to their thickness, the difference in the reported numerical linear buckling loads of the mentioned studies could be due to different thickness values used as inputs for their numerical analyses. In order to address this subject, the present study aimed to provide complete and comprehensive data on the buckling behavior of unstiffened and grid-stiffened cylindrical shells with the same material properties and geometrical dimensions but various thicknesses.

However, ply discontinuities can introduce stress concentrations, potentially damaging the material and adversely affecting its mechanical properties. Evaluating the impact of ply discontinuities on the mechanical properties of CFRP laminate is, therefore, crucial. Extending the applicability of a variational stress analysis based on Hashin’s original approach, this study presents a method to predict local Young’s moduli in unidirectional CFRP laminate with ply discontinuity. The complementary energy for the specific length of the laminate in the longitudinal direction was used to derive the local Young’s moduli. An experimental study and a finite element analysis (FEA) were conducted to validate the results. In the experimental study, strain gauges of various lengths were placed on the ply discontinuity area; the measured Young’s moduli varied with the gauge length. The numerically derived local effective Young’s moduli showed a relatively positive agreement with the experimental and FEA results, especially for lower values of applied stress. For more accurate predictions, future analyses should consider the impact of delamination on the Young’s moduli.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48820945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyamide 6 (PA6) nanocomposites with scCO2-treated EG and MWCNT were prepared by twin-screw extruder-based melt compounding. In the PA6 nanocomposites, the EG sheets were homogenously dispersed, while the MWCNTs were located between the EG sheets, thereby acting as a bridge for the EG. Subsequently, the 35 wt.% imbedding in PA6 nanocomposite had an effective heat transfer pathway and high thermal conductivity (2.12 W m−1 K−1).
