of 0.15-0.2 mm. Fig.1 Optical image of as-prepared sheet-like short carbon fiber preform The compositions of the mixture for sample preparation are listed in Table 1. A typical processing route...J. Cent. South Univ. Technol. (2009) 16: 0881-0886 DOI: 10.1007/s11771-009-0146-08 Thermal-mechanical properties of short carbon fiber reinforced geopolymer matrix composites subjected......
in the optical fiber is lower than the strain of host material. Parametric study shows that a long bonding length and high modulus of protective coating would increase the percentage of strain transferring into the optical fiber. Experiments were conducted by using Mach-Zehnder interferometer to measure the strain of the surface bonding optic fiber induced by the host structure. Good agreements......
glass fiber was fabricated by rotation and rod-in-tube technologies. The ther-mal stability and optical refractive index of the core and cladding glasses were determined by DTA and optical coupler, respectively. The av-erage background loss of tellurite glass fiber was 1.8 dB/m at 1310 nm. Optical microscopy and field emission scanning electron microscope (FESEM) were used to study structural......

Effect of fiber angle on LYP steel shear walls behaviorFarzad Hatami1, Ali Ghamari2, Farshad Hatami3(1. Structure and Earthquake Center, Amirkabir University of Technology, Tehran 15916-34311, Iran;2... exhibits higher properties compared to SSW in both elastic and inelastic zones. It is also concluded that the addition of CFRP (carbon fiber reinforced polymers) enhances the seismic parameters......
