Graphite & Carbon uses in the Aerospace Industry

How graphite is used in aerospace and defence

Why graphite is the ideal material

TYPE OF PRODUCT

APPLICATION

Nozzle throats

The nozzle in a rocket engine sends the gases produced by the burning fuel out of the end of the rocket, propelling it to high speeds.

Applications: Rocket and missile components

Why graphite? Can withstand high temperatures, resistant to corrosion/chemicals, resistant to thermal shock, easy to machine, lightweight

Surface tiles

Each space shuttle is covered by tens of thousands of tiles. Where once these were made of silica fibres, now graphite is being used.

Applications: Shuttle tiles

Why graphite? Can withstand high temperatures, lightweight, good insulator

Heating elements

Furnace fixtures

Plates

Nuts and bolts

Used to create precision-machined plates, nuts and bolts, heating elements and fixtures used in the heat treatment of aerospace metals such as titanium and stainless steel. The heat treatment process strengthens the metals and improves their flexibility.

Applications: Heat treatment of metals

Why graphite? Resistant to high temperatures, resistant to thermal shock, easy to machine

Electrodes

Used in certain machining processes to transmit the electrical charges and remove metal from the workpiece to bring about the desired shape.

Applications: Electrical discharge machining (EDM)—passing an electrical current between two electrodes separated by a dielectric liquid to create an intensely hot spark which can then be used to shape a piece of material. Read more about EDM here.

Why graphite? High melting point, resistant to high temperatures, easy to machine

Vanes

Blades attached to a rotating wheel which push or are pushed by wind or water.

Applications: Fuel pumps

Why graphite? Self-lubricating, resistant to high temperatures, chemically inert

Impellers

Rotating devices consisting of blade-shaped vanes around a central shaft that are designed to alter the flow and/or pressure of liquids and gases. When the impeller rotates, it sucks in the liquid or gas and sends it out the other side.

Applications: Gas injection systems

Why graphite? Chemically inert, resistant to wear, resistant to high pressure
