Tension-tension fatigue behavior of basalt composite hybrid joints

The tension–tension fatigue behavior of pseudo-ductile hybrid bonded-bolted double lap basalt composite joints, composed of pseudo-ductile adhesives and adherends with multi-directional fiber architecture, was experimentally investigated. The fatigue damag ...

Spectroscopic Confirmation of CEERS NIRCam-selected Galaxies at z similar or equal to 8-10

Michaela Hirschmann, Xin Wang

We present JWST/NIRSpec prism spectroscopy of seven galaxies selected from Cosmic Evolution Early Release Science (CEERS) survey NIRCam imaging with photometric redshifts z(phot) > 8. We measure emission line redshifts of z = 7.65 and 8.64 for two galaxies ...

Effect of fiber architecture on tension-tension fatigue behavior of bolted basalt composite joints

Thomas Keller, Lulu Liu, Xin Wang

The effect of fiber architecture, i.e., unidirectional (UD) vs. multi-directional (MD), on the tension-tension fa-tigue behavior of bolted double-lap basalt composite joints was experimentally investigated. The fatigue load-life (F -N) curves of MD and UD ...

Tension-tension fatigue behavior of ductile adhesively-bonded FRP joints

Thomas Keller, Lulu Liu, Xin Wang

The tension-tension fatigue behavior of ductile adhesively-bonded double-lap FRP joints was experimentally investigated. An acrylic adhesive, which was in the rubbery state at ambient temperature, provided the joint ductility. The fatigue degradation of th ...

Optimization of multi-directional fiber architecture for resistance and ductility of bolted FRP profile joints

Thomas Keller, Lulu Liu, Xin Wang

In view of the low structural efficiency of bolted joints in pultruded fiber-reinforced polymer (FRP) profiles with mainly unidirectional (UD) fiber architecture, off-axis plies were considered as an effective way to improve bolted joint performance. An ex ...

Resistance and ductility of FRP composite hybrid joints

Thomas Keller, Lulu Liu, Xin Wang

An experimental investigation of the load-bearing behavior and ductility of FRP hybrid double-lap joints composed of both adhesively-bonded and bolted connection parts was conducted. Amongst other things, the effects of the adherends’ fiber architecture (u ...

Temperature effect on fatigue behavior of basalt fiber-reinforced polymer composites

Thomas Keller, Anastasios Vassilopoulos, Xing Zhao, Xin Wang

In this study, the temperature effect on the static and tension–tension fatigue behavior of basalt fiber‐reinforced epoxy polymer (BFRP) composites is investigated. The S–N curves, energy dissipation, stiffness degradation, and displacement increment with ...

Effects of co-doped barium cerate additive on morphology, conductivity and electrochemical properties of samarium doped ceria electrolyte for intermediate temperature solid oxide fuel cells

Yongpeng Liu, Meng Xia, Xinchao Wang, Jianing Li, Chiara Bonati, Xin Wang

The composite of samarium doped ceria (Sm0.2Ce0.8O2-delta, SDC) and co-doped barium cerate (BaZr0.1Ce0.7Y0.1Yb0.1O3-delta, BZCYYb) is prepared by mechanical mixing and investigated as electrolyte for intermediate temperature solid oxide fuel cells (IT-SOFC ...
