介绍了一系列复合材料的制备、显微组织和一些力学性能和热性能。所研究的系统包括氧化镁、氧化铝、钠钙玻璃、硼硅酸盐玻璃和含有高模铝硅酸盐微晶玻璃、短切碳纤维和含有短切稳定的氧化锆纤维的氧化镁微晶玻璃。当纤维部分排列时,断裂强度增加,但当纤维随机取向时,断裂强度降低。然而,在所有情况下,与未增强的基质相比,断裂功都有显著的增加。从纤维的体积分数、基质与纤维之间热膨胀系数的不匹配以及界面的性质等方面讨论了观察到的影响。
The fabrication, microstructure and some of the mechanical and thermal properties of a series of composites are described. The systems investigated were magnesia, alumina, soda-lime glass, borosilicate glass and a lithia alumino-silicate glass-ceramic incorporating high modulus, chopped carbon fibres and magnesia containing chopped, stabilized zirconia fibres. Fracture strengths were increased when the fibres were partially aligned, but decreased when the fibres were randomly oriented. In all cases, however, a substantial increase in work of fracture was observed compared to the non-reinforced matrices. The observed effects are discussed in terms of the volume fraction of fibre, the mismatch of thermal expansion coefficients between matrix and fibre and the nature of the interface.
