To research the axial compression properties of unidirectional carbon fiber reinforced epoxy resin composite (UCFREP), experiments at different strain rates were carried out by using MTS universal electronic testing machine and equipment split Hopkinson pressure bar (SHPB). Furthermore, finite element analysis (FEA) was also used to study UCFREP with conditions. The true stress-strain curves in quasi-static dynamic obtained, relationship between yield limit rate coupled. microstructure...
Abstract To analyze the mechanical properties of jet penetration on a single-cell / multi-cell liquid composite closed structure, motion equation penetrating metal target is established, and energy system derived. The simulation results show radial convergence effect in increases with increase height inner cavity structure. also has same phenomenon, but phenomenon disjunction appears, which leads to into segments. pressure appears at bottom cell, last cell. distribution concentrated...
The high-quality (0.78-x)BiTi0.1Fe0.8Mg0.1O3-0.22CaTiO3-(x)Na0.5Bi0.5TiO3 nanoscale-thick thin films were prepared successfully on the Pt/Ti/SiO2/Si substrate via sol–gel method. influence of Na0.5Bi0.5TiO3 doping structure, topography, piezoelectricity, ferroelectricity, and dielectricity BTFM-CTO-NBT was investigated systematically. X-ray diffraction Raman results manifested that NBT induced formation tetragonal phase, which existed between rhombohedral orthorhombic phases, elemental...
Abstract (1− x )Pb(Mg 1/3 Nb 2/3 )O 3 – PbTiO (PMN–PT) has attracted attention due to its excellent electrical properties as a typical relaxor ferroelectric material. High‐quality Mn–Sm co‐doped 0.68PMN–0.32PT thin films were synthesized on the Pt/Ti/SiO 2 /Si substrates by sol–gel based spin coating method. The results show that 1 mol% Mn–2 Sm PMN–PT have high dielectric constant ( ε r ∼ 1895) and relatively low loss (tan δ .039) at kHz. They also superior polarization P max 53.71 μC/cm ,...
The relaxor ferroelectric material (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) has attracted great attention due to its excellent electrical properties. High quality Mn-Sm co-doped 0.68PMN-0.32PT thin films were fabricated on the Pt/Ti/SiO2/Si substrates with less oxygen vacancies by using sol-gel based spin coating method. It was found that 2 mol%Sm-1 mol%Mn doped PMN-PT possess high dielectric permittivity (εr ~ 1895.24) and relatively low loss (tanδ 0.039) at 1 kHz, superior polarization (Pmax...
