中文摘要：

石英纤维以铜锌金焊接增强了硅石 composites (QFSC ) 到因钢合金用 Ag-21Cu-4.5Ti 金属 filler 为 10 min 在 1173 K 在真空被执行。实验显示有 CaCO3 micrograins 的 composites prefilled 有好 wettability。在以铜锌金焊接期间分解到 CaO 的 CaCO3。在以铜锌金焊接以后，结构 QFSC/3CaO 的一个关节

英文摘要：

Brazing of quartz fiber reinforced silica composites （QFSC） to Invar alloy was carded out in a vacuum at 1173 K for 10 min using Ag-21Cu-4.5Ti metal filler. Experiments indicated that composites prefilled with CaCO3 micrograins had good wettability. The CaCO3 decomposed to CaO during brazing. After brazing, a joint of structure QFSC/3CaO.2SiO2＋Ti3Os＋Fe2Ti＋NiTi＋Ag（s,s）＋ Cu（s,s）/Invar was established. The shear strength of the brazed joint reached 11.6 MPa at room temperature, which is about five times the shear strength of that obtained without surface filling.
