用Nicalon SiC纤维进行SiC/Al复合材料研究的结果表明,Al对该纤维的润湿性很差。其次,该纤维会与Al发生化学反应损伤纤维从而使其强度下降。因此,寻找一种低温固态复合工艺,如粉浆法,是必要的。粉浆法可避开液态Al不润湿SiC纤维的不利因素,又可降低化学反应速度,从而减少对纤维的化学损伤;此法可在常温下预成形因而可将玻璃 The results of SiC / Al composites with Nicalon SiC fibers show that Al has poor wettability to the fibers. Second, the fiber chemically reacts with Al and injures the fiber, thereby reducing its strength. Therefore, looking for a low-temperature solid-state compounding process, such as the slurry method, is necessary. The slip method avoids the unfavorable factors that the liquid Al does not wet the SiC fiber, but also reduces the chemical reaction speed and thus reduces the chemical damage to the fiber. The method can be preformed at normal temperature so that the glass
