A functionally graded material (FGM) example is ceramic-metal composites. These materials transition from ceramic to metal, providing high thermal resistance on the ceramic side and mechanical strength on the metal side, ideal for applications like thermal barrier coatings and aerospace components.

FAQs & Answers

  1. What are functionally graded materials (FGMs)? Functionally graded materials (FGMs) are advanced composite materials with a continuous distribution of composition and properties, allowing them to have varying characteristics, such as thermal resistance and mechanical strength, tailored for specific applications.
  2. What are the applications of functionally graded materials? FGMs are used in various applications, including thermal barrier coatings in aerospace components, biomedical devices, and automotive parts, where different properties are required in different sections of a material.
  3. How do functionally graded materials differ from traditional composites? Unlike traditional composites that consist of distinct layers or phases, functionally graded materials have a gradual transition in properties, which enhances performance and allows for better handling of thermal and mechanical stresses.
  4. What are some examples of functionally graded materials? Examples of functionally graded materials include ceramic-metal composites, polymer-metal composites, and gradient-structured alloys, each designed to maximize specific properties suitable for their intended use.
