  一、鋁基復合材料概述
  1、 Overview of Aluminum Matrix Composites
  鋁板生產廠家向您介紹鋁基復合材料的知識:
  The aluminum plate manufacturer introduces you to the knowledge of aluminum matrix composite materials:
  1、自20世紀60年代以來,碳纖維、硼纖維、碳化硅纖維、芳綸纖維等高性能纖維得到了發展。以它們為增強材料,以金屬為基體制備復合材料是現代復合材料研究和發展的一個重要課題。

  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、鋁基復合材料和樹脂基復合材料,除了小密度、強度和模量高,線膨脹系數小,和其他特征,也耐高溫、熱導率和電導率高,不易燃,適用于航空航天工業、軍事工業、汽車工業和其它民用行業。
  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、鋁基復合材料的分類
  2、 Classification of Aluminum Matrix Composites
  鋁基復合材料可分為纖維增強型(包括短纖維)、顆粒晶須增強型、層狀型(交替層壓型)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.
  纖維增強鋁基復合材料具有良好的綜合性能。但長纖維價格高,制備工藝復雜,成本高,發展和應用有限,主要用于航天、軍工和少數民用行業。
  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.
  顆粒增強鋁基復合材料制備工藝簡單,顆粒增強材料價格不高,成本低。顆粒增強鋁基復合材料的力學性能雖不如纖維增強鋁基復合材料高,但與基體鋁合金相比,其硬度、模量、耐磨性、疲勞性能、高溫屈服強度和熱穩定性都有較大提高。由于增強體均勻分散在鋁基體中,復合材料各向同性,因此復合材料具有很大的應用潛力。該材料是國內外研究開發的熱點,實際應用范圍不斷擴大。
  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.
