随着现代工程技术的发展,要求工程材料具有更高的综合性能。六十年代初,在碳纤维的研究和生产取得重大进展的情况下,各国相继开展了碳纤维增强金属复合材料的研究。由于碳纤维比重小(1.6～2.0克/厘米~3),强度高(抗拉强度σ_b>200公斤/毫米~2),模量高(2.1～7×10~4公斤/毫米~2,轴向热膨胀系数小(-0.1～-0.23×10~(-6)/℃),用它增强的金属基复合材料既具有高比强度和比模量的特性,又具有导热、导电、高温性能好,尺寸稳定等优良性能。因有这样优异的综合性能,其应用前景广阔,是一种很有发展前途的新型材料。早在1961年,Keppenal和Parikh就尝试用粉末
With the development of modern engineering technology, engineering materials are required to have a higher overall performance. In the early 1960s, with the significant progress made in the research and production of carbon fiber, various countries successively carried out research on carbon fiber reinforced metal composites. Because of the small specific gravity of carbon fiber (1.6 ~ 2.0 g / cm ~ 3), high strength (tensile strength σ_b> 200 kg / mm ~ 2) and high modulus (2.1 ~ 7 × 10 ~ 4 kg / The coefficient of thermal expansion is small (-0.1 ~ -0.23 × 10 -6 / ℃). The metal matrix composites reinforced with it have the characteristics of high specific strength and specific modulus, good thermal conductivity, good electrical conductivity and high temperature performance, Dimensional stability and other excellent performance.Because of such excellent overall performance, its broad application prospects, is a promising new material.As early as 1961, Keppenal and Parikh try to use powder
