aluminum fiber is a high strength, rigid material with very good mechanical properties. It can withstand high and low temperatures. It is also able to absorb shock, which makes it ideal for aerospace applications.
Compared to carbon fiber, it has lower specific tensile strength and stiffness but more thermal expansion and conductivity. Moreover, aluminum has greater corrosion resistance and is able to handle higher temperature ranges than carbon fiber.
It can be welded, soldered and machined in different shapes. It can be used in industries that require a combination of high strength and weight such as aviation, automated machines and professional bicycles. It is easy to work with and can be molded into complex shapes. However, it is prone to corrosion in some environments, and must be treated with care.
A component made from standard carbon fiber can offer up to 31% more stiffness than an aluminium one but weigh 42% less. This can make it a viable alternative to steel, especially for components that have high structural requirements.
In order to prevent galvanic corrosion, a layer of fiberglass or epoxy can be applied over the area where the carbon fiber meets the aluminum. This barrier will prevent any contact between the two materials and protect them from moisture in the air, which would otherwise cause corrosion. Other barriers include painting the carbon fiber or encapsulating the entire area where aluminum and carbon fiber meet. These processes will help to ensure that water and oxygen cannot get to the bonded areas of the composite, which may result in galvanic corrosion.
