Zero-thermal-expansion (ZTE) materials are widely used in precision optics, cryogenic equipment and sensors, where even small ...

Polymer matrix composites (PMCs) are made by reinforcing a polymer-based matrix with glass, carbon, or aramid fibers. PMCs are classified into thermosetting and thermoplastic resins based on the type ...

Carbon fiber reinforced aluminum matrix composites represent a class of advanced materials that integrate the exceptional strength and stiffness of carbon fibres with the lightweight nature and ...

This article was updated May 11, 2023. It was originally published June 1, 2017. Engineers often design structures and components out of metals such as steel and aluminum because of their strength and ...

Metal matrix composites (MMCs) are composite materials containing at least two constituent parts – a metal part and a material or a different metal part. The metal matrix is reinforced with the other ...

The class of materials known as ceramic matrix composites, or CMCs, shows considerable promise for providing fracture-toughness values similar to those for metals such as cast iron. Two kinds of ...

For years, there has been a growing demand for materials that are lightweight with high mechanical strength. Metal matrix composites (MMCs) were developed in order to fulfill this demand and provide ...

Aircraft engine manufacturers have spent years investigating exotic materials, in response to passenger, regulatory and cost pressures, that might reduce engine noise, emissions and specific fuel ...

A quarter-century ago, the Department of Energy began a program to support U.S. development of ceramic matrix composites. In 2016 a new aircraft engine became the first widely deployed CMC-containing ...
