| Abstract: | The coefficlent of thermal expansion and tensile bebavior of three kinds of states and test temperature of SiC_p/LC4 composites fabricated by the compocasting method have been measured and researched Its structure and fractograph have been observed and analysed. It is found that SiC_p/LC 4 composites with oven particulates distribution can be made by the compo-casting method.Its properties are improved and increased.The situation of SiC_p/LC4 interfaces is good. |
