Yan Composites Invests 150M RMB in Advanced Materials Project

Advanced metal matrix composites (MMCs) are engineered materials comprising a metallic matrix (such as aluminum, magnesium, copper, titanium, or steel) reinforced with a secondary phase, typically ceramic or another metal.

• Matrix Materials: Common metallic matrices include aluminum, magnesium, copper, and titanium.
• Reinforcement Materials: Reinforcements can be in various forms, such as short discontinuous fibers (whiskers), continuous fibers, or particulates. Common reinforcement materials include silicon carbide (SiC), alumina (Al2O3), carbon fibers, and boron.
• Key Properties: MMCs are valued for their enhanced properties over monolithic metals, including high specific strength and stiffness, improved wear and corrosion resistance, high thermal conductivity, and thermal stability.
• Manufacturing Methods: Fabrication techniques for MMCs include liquid-state methods (e.g., stir casting, pressure infiltration, squeeze casting, spray deposition), solid-state methods (e.g., powder metallurgy), and in-situ fabrication techniques.
• Applications: MMCs find extensive use in demanding applications across various industries:
  • Aerospace: For lightweight and high-strength components like engine parts, structural elements, and turbine blades, contributing to fuel efficiency and performance.
  • Automotive: Used in engine parts, brake systems, structural components, and power modules (e.g., IGBTs for new energy vehicles) to reduce weight and improve performance.
  • Electronics: Utilized for high-power devices, 5G base stations, and thermal management systems due to their excellent thermal and electrical conductivity.
  • Defense: Applied in armor and protective materials, as well as in advanced military vehicles.
