    Abstract Cracks induced by internal stresses compromise the structural integrity of ceramic laminates. Such stresses can be classified into thermal stress derived from thermal expansion mismatch and shrinkage stress derived from shrinkage mismatch. Analytical models have been proposed for the former, whereas only numerical predictions have been explored for the latter. In this study, an equation is constructed to predict the shrinkage stress by modifying an elastic solution proposed in previous studies. We fabricated laminates with three‐layer sandwiched structures using only alumina specimens with high and low densities to control the shrinkage and avoid thermal mismatch. Surface cracks were initiated when the shrinkage stress exceeded the flexural strength of the surface layer. Although the original strength of the surface layer was 308.8 MPa, the laminates’ flexural strength was lower than that because of shrinkage constraint. Our results demonstrate that the shrinkage stress was successfully estimated analytically using a few material properties measured in an ordinary environment. This study will ensure the structural integrity of ceramic laminates in laminate designs.

    In this article, the stress/stress sensing capability of FeSiB thin films is demonstrated and discussed. The sensing relies on the change in permeability by the application of stress, compressive and tensile, and the application of DC magnetic field. This susceptibility/permeability was tested by the exciting field (AC) being in the same direction with the applied stress. The susceptibility was shown to exhibit a maximal value at a given applied stress, the critical stress. Moreover, this maximal amplitude and position was changing with the application of an external DC magnetic field. For the DC field applied in the direction of the exciting field (AC) and longitudinal to the stress, the critical stress was shifted toward negative values and for the DC field applied perpendicularly, the critical stress was shifted toward larger positive values. This was experimentally demonstrated, and a model was constructed for a better understanding.

    In this study, the inverse magnetostrictive properties of twisted Fe–Co alloy wires and the twisted Fe–Co alloy wire integrated epoxy resin matrix composites were evaluated using free and forced vibration and compressive tests. The inverse magnetostrictive properties of the twisted Fe–Co alloy wires were higher than those of the untwisted wires, with the highest values obtained for the 8-times-twisted Fe–Co alloy wires. However, no clear relationship was observed between the output voltage values and the number of twists. These findings suggested that twisting the Fe–Co alloy wire resulted in residual stress, which may have improved the inverse magnetostrictive properties.

    The magnetostrictive materials are widely used in various fields such as sensors, actuators, energy harvesting devices and so on [1]. Among several magnetostrictive materials, Terfenol-D is widely used for various applications due to its largest magnetostriction at room-temperature while Terfenol-D is expensive. Therefore, we have focused on Fe-Co alloys [2, 3], which are lower cost, have better workability, and higher strength compared with Terfenol-D. It is highly expected that Fe-Co fibers/epoxy composites can be put into practical use as lightweight magnetostrictive materials with an excellent flexibility and a toughness. In this study, we fabricated discontinuous Fe-Co fibers/epoxy composite sheets and investigated its magnetic properties. Fig.1 shows the fabrication process of discontinuous Fe-Co fibers/epoxy composite sheets. The fabricated Fe-Co fibers/epoxy composite sheets of length 70 mm, width 25 mm and thickness 0.45 mm were cut to approximately 6 60.45 mm3 and their magnetic induction vs magnetic field and strain vs magnetic field curves were evaluated. It was revealed that the discontinuous Fe-Co fibers homogeneously dispersed epoxy matrix composite sheets has magnetostrictive properties.

    Silkworm silk is gaining significant attention from both the textile industry and research society because of its outstanding mechanical properties and lustrous appearance. The possibility of creating tougher silks attracts particular research interest. Cellulose nanofiber (CNF) is widely studied for its use as reinforcement for its excellent mechanical properties combined with relatively low density, and also promising biocompatibility. In this study, we demonstrated that CNF dispersed silk fibers had outstanding tensile properties compare to silk without CNF.

It is required a joint technic with excellent mechanical properties to fabricate glass fiber reinforced plastic (GFRP) components. However, it is well-known that the mechanical jointing often causes the fracture of fiber reinforced plastics. It seems that the adhesive bonding is suitable to joint GFRPs, and it is necessary to develop an adhesive with outstanding mechanical properties. Recently, cellulose nanofibers (CNFs) have been obtained from plants by mechanical and chemical methods and it has been reported that CNFs have remarkable mechanical properties. In this study, we inserted epoxy resin with CNFs between GFRP and investigated its bending behavior, to estimate the capability of epoxy resin with CNFs as an adhesive for GFRPs. The flexural behavior and modulus of GFRP was similar regardless of the inserted part of epoxy resin with CNFs layer in GFRP. The flexural strength of GFRP was drastically increased (up to 600 MPa) by the insert of epoxy resin with CNFs of 5 or 10 wt.%, although that of GFRP was decreased by the insert of epoxy resin with CNFs of 25 wt.%. Therefore, it seems that the epoxy resin with CNFs is available as an adhesive for GFRP. However, it is required the observation of CNFs dispersion in epoxy resin to understand the strengthening mechanism of epoxy resin with CNFs.

    © 2018 Trans Tech Publications, Switzerland. TiB whisker reinforced Ti alloy matrix (Ti–TiB) composites have attracted attention as the aerospace materials with their high specific mechanical properties for long time. However, strengthening mechanism of Ti–TiB composites has not been revealed because of the agglomeration and incomplete precipitation of TiB whiskers in the Ti alloy matrix yet. In this study, we addressed to fabricate fully-dense TiB whisker reinforced Ti-6Al-4V alloy matrix (Ti6Al4V–TiB) composites via powder metallurgical process, which have the microstructure to discuss their tensile properties with the theories for composite materials. The Young’s modulus and ultimate tensile strength of Ti6Al4V– 10 vol% TiB composite were 130 GPa and 1193 MPa, respectively. Note that the elongation of Ti6Al4V–10 vol% TiB composite was approximately 2.8% although the elongations of Ti–TiB composite have been reported are few (; less than 1%) due to the agglomeration of TiB whiskers in Ti matrix.

    © 2015 International Committee on Composite Materials. All rights reserved. The development of the aviation industry requires the use of new metallic materials with superior specific mechanical properties compared to existing materials. In particular, the metal matrix composites (MMC) reinforced by nano-particles draw attention due to their excellent machinability. However, it is well-known that handling nanoparticles in industry is problematic due to respect of safety rules regarding nanomaterials. In order to overcome this problem, we have demonstrated the feasibility to fabricate nanocomposite materials without using any starting nanoparticles. We studied the ternary system aluminum/carbon/titanium for which we have shown the possibility to create the nanoparticles of titanium carbide by a flash sintering. So, we fabricated the titanium carbide (TiC) nano particles reinforced aluminum matrix (Al−nano TiC) composite, and demonstrated that the size of TiC nanoparticles could be controlled by both heating rate and dwell temperature. We observed a very narrow size distribution of particles, ranging from 25 to 90 nm. Observation by transmission electron microscopy revealed that the TiC nanoparticles were individually distributed in Al−nano TiC composite and that the Al/nano TiC interface was intimate. Tensile tests have been performed on specimens with various TiC contents. It was found that the ultimate tensile strength of the Al−34 vol% nano TiC composite was higher than 600 MPa with a failure elongation of 4.2 %. The observed ridge of pure Al on the fracture surface implies that pure Al contributes to the conservation of a remarkable failure elongation of the Al−nano TiC composite. The elongation reaches 7.2 % with the TiC volume fraction of 27 %.

    First, this study showed that the enhanced mechanical properties of the cellulose nanofiber (CNF)/silk fibers are attributed to the improved alignment and enhanced dispersion of CNFs inside the silk fiber. Then, PEGDMA/silk fibroin (SF) hydrogels with varying concentrations of SF were developed by digital light projector. The elastic compressive modulus of the printed hydrogel had a wide range of values, suggesting that it could be a good substitute for various stem cells from cartilage, muscle tissue, fat, and bone.

    A magnetostrictive material is deformed by an external magnetic field (i.e. magnetostrictive effect) and changes the surrounding magnetic field by a load (i.e. inverse magnetostrictive effect). Because magnetostrictive material generates electrical power from mechanical impact and vibration using a coil, magnetostrictive material attracts attention as an energy harvesting material. Terfenol-D (Tb-Dy-Fe alloy) and Galfenol (Fe-Ga alloy) are well-known as magnetostrictive materials, However, these materials are brittle (i.e. low workability) and expensive. Hence, magnetostrictive particle dispersed polymer matrix composites have been considered in previous studies. In this study, we focus on Fe-Co alloy and fabricated Fe-Co alloy particle dispersed cellulose nanofiber (CNF-FeCo) paper and investigated their magnetostriction. Few CNF-FeCo paper showed higher magnetostriction (close to 200 ppm) than that of Fe-Co thin film (70 ppm).

    In this research, the thermal energy harvesting and piezoelectric response behavior for the lead-free piezoelectric composite materials were studied from both numerical simulation and experiment. Specifically, piezoelectric/Cu unimorph and piezoelectric nanoparticle dispersed polymer films were fabricated, and output voltage measurement due to temperature change and piezoelectric response evaluation were performed. Moreover, multi-physics numerical simulation was carried out and theoretical examination was added to the experimental result. Furthermore, the material and structure optimization of piezoelectric composites was discussed.
