Thirty years ago, GE Aerospace transformed commercial aviation with a material swap that most ...

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 ...

Polymer matrix composites are highly susceptible to damage when used in various environmental extremes. This susceptibility results from a number of physical factors common to polymers in general and ...

Polymers are composed of very large molecules formed by a combination of different monomers (smaller and simpler molecules), which can be natural or synthetic. Polymers are the basis of many ...

Liquid electrolytes enable fast ion transport but can raise safety concerns, and lithium metal anodes—despite their high capacity—can grow dendrites that trigger short circuits and rapid failure.

Ceramic matrix composites (CMCs) and metal matrix composites (MMCs) have long played an important role for the military and aerospace in protecting military vehicles, as well as spacecraft and space ...

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 ...

Individuals from many disciplines confront the challenge to understand the full range of factors surrounding the evolution of micro- and macrostructure of a PMC during its lifetime in extreme ...
