序言当在实际中发现用连续长的金属纤维和陶瓷纤维来强化金属越来越得到应用的时候,短纤维强化金属的工艺还处于发展阶段。发展较晚的原因,一方面由于缺乏相应短而且均匀的强化纤维。另一方面由于发展定向嵌入短纤维在技术标准上可实现的工艺不完善。除此之外,由于短纤维或品须具有特殊的抗张强度和弹性模量,因此它们的价格还相当高。这对于顺利地发展一种较为理想的晶须是有困难的。碳化硅晶须的质量目前有了显著的提高,是由于近几年来关于晶须长大方法和分类方法得到改进。制取工艺在相应发展的情况下,晶须价格比目前市埸上出售的陶瓷纤维(连续的)有了显著的下降。 INTRODUCTION The practice of short fiber-reinforced metal is still in its infancy, as it has been found in practice that reinforcing metals are increasingly used with continuous lengths of metallic and ceramic fibers. The reason for the later development, on the one hand, is due to the lack of corresponding short and uniform reinforcing fibers. On the other hand due to the development of directional embedded short staple technology standards can be achieved imperfect. In addition, they are still relatively expensive due to their special tensile strength and modulus of elasticity. This is difficult for the smooth development of a more desirable whisker. The quality of silicon carbide whiskers has now been significantly improved due to improvements in methods and classification of whiskers in recent years. In the case of corresponding developments, the price of whiskers has dropped significantly from that of ceramic fibers (continuous) sold on the market today.
