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 ...

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 ...

Copper matrix composites (CMCs) are engineered materials in which a copper matrix is reinforced by ceramic particles, carbon-based nanomaterials or other high-strength inclusions to enhance mechanical ...

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 ...

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 ...

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 ...

Ceramic matrix composites (CMCs) have emerged as a critical class of materials for demanding high-temperature applications due to their unique combination of properties, including: However, ...

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 ...

An extruded wood polymer composite (WPC) green body that has then been carbonized into a porous preform and then processed via silicon melt infiltration into a high-performance silicon carbide (SiC) ...
