In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic (such as alumina or silicon carbide) or another metal (such as steel). They are typically classified according to the type of reinforcement: short discontinuous fibers (whiskers), continuous fibers, or particulates. There is some overlap between MMCs and cermets, with the latter typically consisting of less than 20% metal by volume. When at least three materials are present, it is called a hybrid composite. MMCs can have much higher strength-to-weight ratios, stiffness, and ductility than traditional materials, so they are often used in demanding applications. MMCs typically have

  • Un composite à matrice métallique (CMM) est un matériau réunissant deux éléments : * une matrice métallique, par exemple en aluminium, magnésium, zinc,… * un renfort métallique ou céramique, tels que des fils d’acier, particules de carbure de silicium (SiC), fibres de carbone, alumine,… Les composites à matrice métallique ayant de la céramique comme renfort sont appelés cermets. Le sigle MMC constituent l’acronyme de « Metal Matrix Composite », i.e. « Composite à matrice métallique » ou CMM en français. (fr)
  • 金属基复合材料（Metal Matrix Composite，MMC）一般是以金属或合金为连续相而颗粒，晶须或纤维形式的第二相组成的复合材料。目前其制备和加工比较困难，成本相对较高，常用在航天航空和军事工业上。现在复合材料生产加工技术已经相对比较成熟，民用，商用领域均有使用。 (zh)
  • مركب معدني هيكلي (بالإنجليزية: (metal matrix composite (MMC) هو مادة مؤلفة تتكون من عضوين على الأقل ويكون أحدهما معدن. وقد يكون العضو الآخر معدن آخر، أو مادة أخرى مثل خزف أو مركب عضوي.ويسمى المركب المتكون على الأقل من 3 مواد مركب هجيني. ويتكون المركب المعدني الهيكلي من هيكل معدني مدعم في داخله بمواد مقوية من السيراميك أو مادة عضوية تكون عادة في صورة ألياف. وقد وجدت تلك المواد التطبيق أول مرة في بناء مكوك الفضاء عام 1975. حيث ابتكرت مواد خفيفة، تبلغ كثافتها بين 8و1 - 5و3 جرام/شمنتيمتر مكعب، لا تنفرط بسهوله، وتتميز بتوصيل حراري مرتفع ومعامل تمدد حراري منخفض.

  • Metallmatrix-Verbundwerkstoffe (engl. metal matrix composite, MMC) bestehen aus einer zusammenhängenden Metallmatrix mit einer diskontinuierlichen keramischen oder organischen Verstärkung in ihrem Inneren, häufig in Form von Fasern oder Whiskern. Auch so genannte Preform-MMCs, bei denen beide Phasen kontinuierlich sind, werden häufig als MMCs bezeichnet. Eine der ersten Anwendungen war der Einsatz im Space-Shuttle-Programm ca. 1975. Dabei handelte es sich um einen sehr leichten (ca. 1,8–3,5 g/cm³), schwer zerspanbaren Werkstoff mit guter Wärmeleitfähigkeit und geringer Wärmeausdehnung. Auch andere Eigenschaften lassen sich bei der Herstellung den Anforderungen entsprechend gezielt einstellen. (de)
