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 ...

A nanocomposite is a multiphase solid material in which one of the phases has one, two or three dimensions of below 100 nm, or structures with nanoscale repeat distances between the different phases ...

Ceramic matrix composite (CMC) materials are made of coated ceramic fibers surrounded by a ceramic matrix. They are tough, lightweight and capable of withstanding temperatures 300-400 degrees F hotter ...

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 ...

Demand continues to increase for ceramic matrix composites (CMC), which enable reduced weight and high performance at higher temperatures versus metals. This increases efficiency in engines, ...

It's taken a long time to tweak ceramic matrix composites (CMCs) so they can be produced in high volumes, but the time has finally come. Aircraft engine leader GE Aviation has broken ground on the ...

CMCs are made up of two major components: a reinforcing material for strength and stiffness and a matrix material to hold the composite together. CMCs have both ceramic reinforcement and matrix. This ...

GE Aviation’s two new plants will help to establish a supply chain for CMCs needed for rapidly expanding jet engine demand, in particular the LEAP turbofan engine. It already is producing super-alloy ...

A second-stage rocket nozzle extension would be fixed and is intended to improve performance and reduce costs. Credit: Firefly The Air Force Research Laboratory (AFRL) has awarded Firefly Aerospace a ...

At GE Aviation's ceramics lab in Newark, Del., workers load molded CMC forms into an autoclave, to set the shape prior to thermal processing, to remove the polymer and leave “a hollow shell” of ...
