Precious metal fibre composites
Precious metal fibre composites are composite materials made up of precious metal fibres and a polymer matrix. The combination of the two materials, metal and polymer, gives the composite material unique properties, making it suitable for a wide range of applications.
Precious metal fibre composites are strong and lightweight, and they are able to resist corrosion and wear, making them ideal for a wide range of industrial and consumer applications. The lightweight nature of the composite makes it particularly attractive for applications such as aircraft and other transportation uses, where fuel efficiency is an important factor. The corrosion resistance makes the material useful for marine and chemical process equipment, where corrosion resistance is a priority.
The composition of the composite is largely dependent on the ratio of metal to polymer used. It is possible to create composites with a range of different ratios, depending on the desired properties of the composite. The most common form is a composite containing two-thirds metal to one-third polymer. This ratio provides the composite with the strength and corrosion resistance required for many applications, while also allowing some flexibility.
The metal used in the composite can be either a precious metal, such as gold or silver, or an alloy of a precious metal. The advantage of using a precious metal is that it can provide the composite with properties such as corrosion resistance and wear resistance. However, using an alloy can also have advantages, as alloying can improve the strength and other mechanical properties of the composite.
The polymer matrix used in the composite can also have a large effect on the properties of the composite. The polymer matrix serves to bind the fibres together, providing stability and strength to the composite structure. Different polymers have different properties, and the choice of polymer can have a large effect on the properties of the composite. Commonly used polymers include polyethylene, epoxy, and polyurethane.
In addition to the polymer and metal, additional materials can be added to the composite in order to provide desired properties. Materials such as carbon fibre or glass fibre can be added to the composite to improve strength or rigidity.
The properties of the composite will depend on a range of factors, including the ratio of metal to polymer and the type of polymer and additional materials used. The benefits of the composite depend on the application – for example, the lightweight nature of the composite makes it desirable for aircraft, while the corrosion and wear resistance makes it suitable for marine use. The flexibility of the material also makes it attractive for applications such as housing components. As such, the range of applications for precious metal fibre composites is broad and expanding.
