title: Flexural properties of lightweight carbon fiber/epoxy resin composite sandwiches with different fiber directions

description: The unidirectional CFRP laminates were prepared using the carbon fiber prepreg (CF, ZFS Materials Co., Ltd) by hot-pressing method. he lightweight pumice/Mg core was fabricated by pressure-infiltration method. In short, the selected pumice particles with the size of 3–4 mm were transferred into a cylindrical mould. Then, the molten magnesium was infiltrated into the gaps between pumice particles under vertical pressure. After solidification, the pumice/Mg core was processed to the required size for subsequent experiments.The length, width and thickness of the core material are 60 mm, 15 mm and 10 mm, respectively. The lightweight pumice/Mg core is between two thin CFRP skins, and the core material and CFRP skins are tightly bonded by epoxy adhesive under low pressure. After 24 h of curing, the composite sandwiches for the test were obtained. Three types of composite sandwiches with pumice/Mg core were obtained by using the CFRP skins with different fiber directions.

title: The original dataset of the thesis, weak coherent light interference heterodyne detection based on time-domain signal analysis
title: 论文《weak coherent light interference heterodyne detection based on time-domain signal analysis》的原始数据

description: We used a weak coherent light source with a central wavelength of 840 nm and a full width at half maximum (FWHM) of 25.429 nm to generate the weak coherent light. A 50:50 fiber coupler split the weak coherent light and directed it toward the optical delay line and simulated sample. A photodetector finally detected the optical signals. A reflecting mirror simulated the sample and generated the weak coherent interference heterodyne detector signal.During detection, the motor moved in a uniform linear motion at a speed of 5.25 mm/s. This caused the optical distance difference between the optical delay line and the simulated sample to change at a speed of 21 mm/s. The heterodyne detection frequency of the cosine component in the interference signal is approximately 25,110 Hz.

title: Microstructure and mechanical properties of SiCf/SiC brazed joints
title: SiCf/SiC钎焊连接微观组织及力学性能研究

description: Background: Continuous SiC fiber-reinforced SiC-matrix composites (SiCf/SiC) can be used as the fuel cladding, control rod sheath, intermediate heat exchanger, and tube components for nuclear reactor, the reliability of its joining would be crucial to the safety of nuclear energy. Purpose: This study aims to connect SiCf/SiC with SiCf/SiC using brazing method. Methods: SiCf/SiC was prepared by chemical vapor infiltration (CVI) method. Active brazing method was used to join SiCf/SiC under 850℃, 870℃, and 890℃ with Ag-26.77Cu-4.4Ti (wt. %) filler metal. The microstructure and interfacial phase of the brazed joint under different temperatures were analyzed for a high joining performance using optical microscopy (OM), scanning electron microscope (SEM), and energy dispersive spectrometer (EDS). The mechanical properties of the brazed joint were analyzed using thermal simulated test machine. Results: The results indicated that AgCuTi filler could realize stable joining for SiCf/SiC, and the surface smoothing of SiCf/SiC was beneficial to improve the shear strength of the joint. Conclusions: When the brazing temperature reached 890 °C, the brittle phase of Ti5Si3 gradually diffused and diffusely distributed to the brazing seam, and the reinforced phase TiC became the main component of reaction layer, which effectively improved the microstructure and significantly increased the strength of the SiCf/SiC brazed joint.

title: "Effect of Nanofiller on the Mechanical Properties of Carbon Fiber/Epoxy Composites under Different Aging Conditions"

description:  The raw materials used in this study were unidirectional carbon fiber fabric (CF, ZFS Materials Co., Ltd., Wuxi, China) and bisphenol-A E51 resin (EP, Nanton Synthetic Materials Co., Ltd., Wuxi, China).The weight of the carbon fiber is 300 g/m2, and the thickness is 0.167 mm. Surface-treated MWCNTs were purchased (Zhongke Nano Materials Co., Ltd., Chengdu,  China), and they were treated with a mixture of sulfuric acid and nitric acid (3:1), which introduced oxidation groups on the CNTs. The MWCNTs were stirred evenly in an  acetone solvent for 2 h to obtain MWCNT acetone dispersion. Then, the MWCNT acetone dispersion was added to an E51 solution to achieve 0.5 wt.% content and sonicated at about 60 Cforanother 2 h under a power of 40 kHz. Surface-treated halloysite nanoclay (Mingchuang Materials Co., Ltd., Xi’an, China) was added to an appropriate amount of epoxy resin to achieve 2 wt.% content under stirring for 2 h at 25 C. Then, the nanoclay-resin mixture was taken out. The resin/nanofiller mixture was infiltrated into CF fabric to prepare a prepreg. The prepreg was placed in the air for 72 h and then dried in a vacuum oven at 60 C for 2.5 h. The unidirectional CFRP laminates were prepared by a molding process at a pressure  of 1.1–1.3 MPa. The thickness of the CFRP laminates is about 2 mm.

title: Improved corrosion resistance of friction stir welded magnesium alloy with micro-arc oxidation/electroless plating duplex coating

description: The bare FSW joint was immersed in a NaCl solution with 3.5 wt% content for 0.5 h at room temperature, and the coated FSW joint was immersed in a NaCl solution for 6 h; the corrosion resistance was analyzed by observing the macro and micro-morphology of the corrosion surfaces. The electrochemical measurements were performed using a Gamry 3000 instruments. The sample was selected as the working electrode and the Pt foil was served as the counter electrode. A saturated calomel electrode (SCE) was used as the reference electrode. The sample reached the potential steady-state after being immersed in a NaCl solution for about 30 min. Electrochemical impedance spectroscopy (EIS) was applied at open circuit potential. The amplitude of the AC potential disturbance was 10 mV, and the frequency of the AC signals ranged from 100 kHz to 0.01 Hz. The EIS measurements for the duplex coatings were performed for passing immersion time of 0.5 h and 26 h. At least five samples were used to ensure the repeatability of the data. The polarization curve from the cathodic to anodic potential was determined at a scanning rate of 1 mV s 1. It should be noted that after polishing, the exposed area of the thermo-mechanically affected zone (TMAZ) was too small for electrochemical measurements. Therefore, no electrochemical measurement was obtained in the TMAZ.

title: Compressive property and energy absorption characteristic of interconnected porous Mg-Zn-Y alloys with adjusting Y addition

description: The pore size of porous Mg-Zn-Y was calculated by the Nano Measure digital photography and image analysis soft-ware. The microstructures of the porous Mg-Zn-Y were ob-served using an optical microscope (OM, MDJ-DM320). The second dendrite arm spacing (SDAS) and the volume fractionof the second phase were counted by the OM image software (Nano Measure and Image J). The phase compositions of the porous Mg-Zn-Y were de-tected with X-ray diffraction (XRD, Cu-K α, D/MAX-2500). The microstructure and phase morphology of the porous Mg-Zn-Y were observed by a scanning electron microscope (SEM, ZEISS EVO-18, TESCAN VEGA3) equipped with an X-ray energy-dispersive spectrum analyzer (EDS, OXFORDModel Link-Isis). The SEM samples were selected from foam struts. These foam struts were ground using many abrasive pa-pers. Afterwards, they were mechanically polished and then etched in a mixed acid solution for approximately 12 s. The details of the microstructure and phase structure were further observed by a transmission electron microscope (TEM, JEOL JEM-2100F). The TEM sample was selected from the foam struts. The foam struts were grinded to make thin foils. These foils were pretreated using the argon ion thinning tech-nique for further TEM observation.
