  一、铝基复合材料概述
  1、 Overview of Aluminum Matrix Composites
  铝板生产厂家向您先容铝基复合材料的常识:
  The aluminum plate manufacturer introduces you to the knowledge of aluminum matrix composite materials:
  1、自20世纪60年代以来,碳纤维、硼纤维、碳化硅纤维、芳纶纤维等高性能纤维得到了发展。以它们为增强材料,以金属为基体制备复合材料是现代复合材料研究和发展的一个重要课题。

  1. Since the 1960s, carbon fiber, boron fiber, silicon carbide fiber, aramid fiber and other high-performance fibers have been developed. It is an important subject for the research and development of modern composite materials to prepare composite materials with them as reinforcement materials and metal as matrix.
  2、铝基复合材料和树脂基复合材料,除了小密度、强度和模量高,线膨胀系数小,和其他特征,也耐高温、热导率和电导率高,不易燃,适用于航空航天工业、军事工业、汽车工业和其它民用行业。
  2. Aluminum matrix composite materials and resin matrix composite materials, in addition to small density, high strength and modulus, small coefficient of linear expansion, and other characteristics, also have high temperature resistance, high thermal conductivity and conductivity, and are not flammable. They are suitable for aerospace industry, military industry, automobile industry and other civil industries.
  二、铝基复合材料的分类
  2、 Classification of Aluminum Matrix Composites
  铝基复合材料可分为纤维增强型(包括短纤维)、颗粒晶须增强型、层状型(交替层压型)和定向凝固共晶型。
  Aluminum matrix composites can be divided into fiber-reinforced type (including short fiber), particle whisker reinforced type, layered type (alternating lamination type) and directional solidification eutectic type.
  纤维增强铝基复合材料具有良好的综合性能。但长纤维价格高,制备工艺复杂,成本高,发展和应用有限,主要用于航天、军工和少数民用行业。
  Fiber reinforced aluminum matrix composites have good comprehensive properties. However, the long fiber with high price, complex preparation process, high cost and limited development and application is mainly used in aerospace, military industry and a few civil industries.
  颗粒增强铝基复合材料制备工艺简单,颗粒增强材料价格不高,成本低。颗粒增强铝基复合材料的力学性能虽不如纤维增强铝基复合材料高,但与基体铝合金相比,其硬度、模量、耐磨性、疲劳性能、高温屈服强度和热稳定性都有较大提高。由于增强体均匀分散在铝基体中,复合材料各向同性,因此复合材料具有很大的应用潜力。该材料是国内外研究开发的热点,实际应用范围不断扩大。
  The preparation process of particle reinforced aluminum matrix composite is simple, the price of particle reinforced material is not high, and the cost is low. The mechanical properties of particle reinforced aluminum matrix composite are not as good as that of fiber reinforced aluminum matrix composite, but compared with the matrix aluminum alloy, its hardness, modulus, wear resistance, fatigue performance, high temperature yield strength and thermal stability are greatly improved. Because the reinforcement is uniformly dispersed in the aluminum matrix and the composite is isotropic, the composite has great application potential. This material is a hot spot of research and development at home and abroad, and its practical application scope is expanding.
