Non Metal Spacers

Non-metal spacers are low-cost, high precision components that are used in airframes where there is a requirement to keep parts of the airframe away from other parts. 

An example of this is maintaining a distance between wiring or tubing and the body of the aircraft. Spacers can be made out of metal or non-metal materials.  The choice of material will depend on the specific requirements of the spacer, and its location in the airframe.

Rubber spacers

Rubber is a flexible material with properties that mean that it functions well in low temperatures.  It is also characterised by high tensile strength, excellent resistance to abrasion and to tearing.  It would be less appropriate for environments where it would be exposed to heat, UV light or exposure.

Nylon spacers

Nylon is strong, resistant to abrasion and tough.  With its low-friction properties, it is easy to work with and is therefore a popular choice for spacers in airframe production.

Plastic spacers

Plastic spacers have high levels of electrical and thermal insulation and so can be valuable where this is a requirement.  They are also resistant to moisture and so can be used in environments where humidity is a factor. They can be a low-cost option that are highly appropriate for a range of uses.

Composite spacers

Composite materials can be manufactured to encompass a number of properties that might be essential for safety and efficiency in a range of airframe environments.  They are more costly than some other non-metal options, but are flexible and can be manufactured to meet very specific needs.
