A host of high-technology applications require materials that have specific and unusual properties that cannot be met by any of the monolithic conventional metals, ceramics, and polymers. Some of these requirements have been met through the judicious combination of two or more distinct materials into composite materials that possess materials properties better than those found in the monolithic classes of materials. In this lesson, we will organize the composites into four main classifications and explore the strengths, as well as many of the current applications of these materials.
By the end of this lesson, you should be able to:
- Define and contrast the use, cost, and ease of fabrication of polymer-, ceramic-, and metal-matrix composites.
- List and define the four main classifications of composite materials.
- Note the three common fiber reinforcements used in polymer-matrix composites and, for each, cite both desirable characteristics and limitations.
- Cite the desirable features of metal-matrix composites.
- Note the primary reason for the creation of ceramic-matrix composites.
- Name and briefly describe the two sub-classifications of structural composites.
