(Cf/SiO2) composite materials have been developed by Guo and Yen[69]. Compared with silica glass, the strength and toughness of Cf/SiO2composite have been greatly improved. The strength has been increased to 11 times and the work of fracture has been increased to two orders of magnitude. ...
glass, and the correlation coefficient γ = −0.29 was determined. After super−polishing, the mechanical properties of the sample surface become significantly uniform with a roughness of Rq = 0.06 nm and Ra = 0.05 nm, and the correlation coefficient becomes γ = −0.02. Moreover, the ...
In the absence of resonances with intermediate atomic states, Formula (5) allows one to directly determine the multiphoton absorption cross-section (see Expression (1)). Similar ideas about the processes of tunnel and multiphoton ionization in dielectrics, which govern the transitions of electrons ...
with 1592 loading cycles when printed with an orientation angle of 15°–75°. The number of loading cycles was 290 and 39 when printed with the same orientation angle for the Flat and Upright printing directions, respectively. This result underscores the importance of orientation in the ...
The warpage and adhesion problems associated with the 3D printing of MDPE-based materials were solved using a HDPE build plate instead of the glass one. Using a HDPE substrate, it was possible to print complex samples due to the low interfacial tension between MDPE and the HDPE build plate, ...
(UTS) of 78.3 MPa and 43.9 MPa in the XY- and Z-directions of 3D printing, respectively. The effect of the filler on the crystallization kinetics, which is a key parameter for the selection of semicrystalline materials suitable for 3D printing, was explained. This work clearly shows that ...
selective surface with full transmission at the resonance frequency. FD-FSCs embedded radar absorbing structure (RAS) demonstrates an excellent microwave absorption and a wide effective bandwidth. At a thickness of 4.3 mm, the 10 dB bandwidth covered the entire X-band (8.2~12.4 GHz) range of ...
The acousto-electric (AE) effect associated with the propagation of Rayleigh and Sezawa surface acoustic waves (SAWs) in ZnO/fused silica was theoretically investigated under the hypothesis that the electrical conductivity of the piezoelectric layer has an exponentially decaying profile akin to the phot...
[54] produced nylon composite material specimens at three different raster directions, i.e., 0, 90, and 45. The performance of the carbon and glass fiber reinforcements was evaluated using three-point flexural testing, with nylon serving as the matrix material. Wu et al. [55] in their ...
