Fusion Splicing Experiments of 1060-XP silica fiber with Phosphate Glass fiber

Journal of Wuhan University of Technology(Materials Science) 2007年第B12期22卷 847-849页

作者：杨昌盛杨中民 Institute of Optical Communication Materials South China University of Technology

An asymmetric heating method for fusion splicing of 1 060-XP silica fiber （1 060F） and phosphate glass fiber （PGF） using an electric arc splicer has been proposed. Double joints with the lowest splice loss of 0.6 dB and good bending-resist strength between 1 060 F and PGF has been obtained. The main reasons affecting fiber splice loss and strength have been analyzed.

Science China(Technological Sciences) 2005年第6期48卷 685-691页

作者： QI Gongjin ZHANG Changrui HU Haifeng CAO Feng WANG Siqing JIANG Yonggang State Key Laboratory of Advanced Ceramic fibers and Composites College of Aerospace and Materials EngineeringNational University of Defense TechnologyChangsha 410073China

Perhydropolysilazane,a low viscosity preceramic polymer with good wettability and high char yield,was used to fabricate three-dimensional silica fiber reinforced silicon nitride matrix composites through the repeated infiltration-curing-pyrolysis *** the increase of the pyrolysis temperature from T_(1),T_(2)to T_(3),the density of the composites increased all through,but the flexural strength showed a maximum value at T_(2)followed by a sharp *** composite prepared at T_(2)exhibited a good ceramization of the preceramic polymer,a high flexural strength of 144.9 MPa and excellent dielectric *** high performance of the composite resulted from the good state of the silica fibers,controlled fiber/matrix interfacial microstructures and high-purity dense silicon nitride matrix.
