The development of practical and efficient electromagnetic wave (EMW) absorbing materials is a challenging research problem. A mussel-inspired molecular structure regulation strategy using polydopamine to increase the roughness functional groups basalt fiber (BF) surface, which can improve interfacial adhesion. Herein, novel BF-Fe3O4/CNTs heterostructure synthesized through dip-coating adsorption process. three-dimensional network Fe3O4/CNTs hybridin situanchored on surface BF, endows...
With the rapid increase in scale and number of tunnels cold regions, frost damage problems, such as cracking lining structure under action freeze–thaw cycles are becoming increasingly prominent. This review article collects sorts out phenomena that occur regions freezing thawing cycles, classifies into structural non-structural damage, proposes research on mechanism its prevention measures should focus cracking. According to degree cycle influence tunnel operation, mode stage introduced. The...
ABSTRACTABSTRACTBasalt fibers (BF)-reinforced double-layered resin composite with excellent absorption performance in X band (8.2–12.4 GHz) has been designed, choosing carbon black (CB) and nano-Fe3O4 as absorbent for absorbing layer matching layer, respectively. The electromagnetic parameters of the composites were measured by vector network analyzer using waveguide method. calculated result suggests that an increased amount could significantly improve microwave absorbability single-layered...
Abstract In this paper, rice husk (RH) was used as raw material to prepare white carbon black, and the key technological parameters of preparing black from RH were studied through single‐factor test, orthogonal experiment, response surface analysis. Meanwhile, characteristic also analyzed. Through experiment analysis, it confirmed that order factors affecting purity calcination temperature > alkali treatment time final pH surfactant. Based on optimization optimum for preparation follows:...
The microstructure, pore structure and changes in electromagnetic parameters of cement paste prepared with nano carbon black (CB) were analysed. results showed that the addition CB significantly influenced paste, increasing content pores less than 100 nm improving overall structure. use dispersant further enhanced dispersion increased its filling effect. also had a significant impact on compressive strength presence certain agglomerates reducing strength. However, when (CBC) was 0.5 wt%,...
To study the variation laws and effects of asphalt mastic under cooperative interaction different temperatures humidities, cyclic conditions for temperature ranges were set to conduct indoor experimental simulations thermal–humidity coupling cycles. Firstly, macroscopic performance changes in styrene butadiene polymer (SBS)-modified evaluated by penetration test, softening point ductility Brookfield rotational viscosity double-edge notched tensile (DENT) test; then, mechanism was explored...
The objective of this study is to investigate the damage mechanism a multi-beam steel–concrete composite bridge under car explosion. widely used in expressways and urban viaducts. Explosives are distributed multiple locations above deck avoid stress concentration. explosion analysis carried out with equivalent trinitrotoluene 50 kg, which represents state full oil tank. multi-Euler domain method based on fully coupled Lagrange Euler models adopted for structural process commercial software...
When processing marine controlled-source electromagnetic (CSEM) data from a rugged seafloor, enhancing the reservoir response and suppressing topographic effect other interference are significant issues, especially in shallow water. We simulated CSEM responses specific to these issues using an efficient finite-difference (FD) code. The synthetic aperture technique was applied steer EM field toward high-resistivity target on seafloor. A weighted 2D source constructed by imposing real...
<p indent="0mm">Earthquake-resilient underground structures can reduce earthquake-induced damage, protect life and property, maintain their functions with minor or no repair after an earthquake. As earthquake-resilient cities are increasingly developed, improving the seismic resilience of has become a popular topic in research on structure earthquake engineering. This paper systematically summarizes progress improved urban structures. The principle is first introduced. Then, latest...
Health assessment and defect mechanism analysis of four-row roller bearings (FRRBs) in high precision rolling mills is a challenging task. This due to the opaque information environment surrounding complex conditions encountered during operation. Imprecise health fuzzy FRRBs often resulting rapid growth defects sudden shutdown mill. Despite their crucial role process, relevant methods, models improvement measures have not been thoroughly explored. The operators industrial plant mostly rely...
