J. Cent. South Univ. Technol. (2011) 18: 1833-1837 DOI: 10.1007/s11771-011-0910-4 Dissolution behavior of calcium-magnesium-silicate glass fiber LIU Hao(刘浩), WANG Xi-tang(王玺堂), ZHANG Bao-guo(张保国... Berlin Heidelberg 2011 Abstract: The dissolution behavior of CaO-MgO-SiO2 glass fiber was investigated by scanning electron microscopy (SEM), Fourier-transform infrared spectrometer (FTIR......
through the Faraday angle in the sensing fiber. The mirror attached at the end of the sensing fiber reflects the polarized light. When the reflected light propagates back to the sensing fiber, the second.... And the suppression methods of the major stochastic noise are proposed. Key words: stochastic noise; stray current; optical fiber current sensor 1 Introduction Optical fiber current sensor (OFCS) has drawn wide......

footings adjacent slopes, 2) suggest an optimum number of reinforcement and 3) survey the effect of friction angle in clayey soils reinforced by geogrids. The investigations were carried out... increases with an increase in edge distance. In addition, as the soil friction angle is increased, the efficiency of reinforcing reduces. Key words: geosynthetic reinforcing; numerical analysis; bearing......
J. Cent. South Univ. Technol. (2008) 15(s1): 564-567 DOI: 10.1007/s11771-008-422-z Evaluation of statistical strength of bamboo fiber and mechanical properties of fiber reinforced green... fiber were analyzed, and the tensile strength of green composites was also investigated. The result confirms that the tensile statistical strength of fiber fits well with two-parameter Weibull......
of the flat jet with an inclination angle was investigated by a water model. A mathematical model for the shrinkage and the trajectory of the flat jet with an inclination angle was derived theoretically and verified by experimental data of the water model. The experimental results indicate that the inclination angle (α) has no influence on the shrinkage of the flat jet, the shrinkage of the flat jet along......
angle for woven composite is about 30°. The bending load is smaller than 5 N in the stamping process and decreases with the increase of temperature. The optimal temperature to form the carbon fiber... fiber composite sheet; shear angle; bending; deep drawing 1 Introduction Compared with other commonly used materials such as metals and alloys, fiber composites possess excellent features such as low......
