【摘要】 <正> SiCw/Al复合材料兼有铝的比重和钛的强度,是一种很有前途的新型材料。它在战斗机尾翼结构和汽车发动机中的应用已经引起了世界各国普遍的关注。 对SiCw/Al复合材料的力学性能在文献(1,2)中进行了阐述,本文仅对SiCw/Al复合材料的热膨胀性能和热传导性能的研究结果给予报导。更多还原

【Abstract】 The properties of heat expansion and thermal conduction in a silicon carbide whisker reinforced aluminium (SiCw/Al) composite have been studied by comparative test with 6061 aluminium alloy matrix in the composite. The experimental results showed that the SiCw/Al composite has a good thermal conductivity. Its expansion coefficient is nearly equal to that of the matrix.更多还原
