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 ...

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 ...

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 ...

Toughening has always been an important research direction of structure ceramics. The addition of secondary phases to the ceramic matrix to prepare composite ceramics is an effective toughening ...

Composite materials are engineered by fusing different materials, typically consisting of a matrix (a polymer, metal, or ceramic) and a reinforcement (such as fibers, particles, or flakes) that ...

Carbon fiber-reinforced ultra-high-temperature ceramic (UHTC) matrix composites are extensively used in space shuttles and high-speed vehicles. However, these composites suffer from a lack of ...

Engineers at the National Composites Centre (NCC) have completed a European first by manufacturing Ceramic Matrix Composites (CMCs) using Automated Fibre Placement (AFP) technology, paving the way for ...

As the chip manufacturing industry continues to expand in New York, one company in Saratoga Springs is hoping to carve out its own niche — silicon carbide production. Free Form Fibers has been ...

Decarbonization goals call for advancing high-impact energy technologies. The U.S. has pledged to achieve net-zero emissions by 2050, a goal that presents both challenges and opportunities in the ...
