The unique properties of our knitted wire mesh make it an ideal choice for many demanding aerospace applications where few materials will withstand the challenging installed and environmental conditions typically encountered.
The flexibility (ability to be bent without breaking) and malleability (the ability to withstand plastic deformation without fracture) of our products can be designed according to customer needs. Through a careful selection of materials, mesh structure, and tooling design, we can produce mesh components in an almost limitless range of shapes including sheets (blankets), highly flexible hollow mesh tubes, and 3-dimensional rigid structures such as prisms, cubes, spheres and doughnuts, etc.
Depending on the design of the mesh and the materials used, knitted wire mesh structures can absorb energy elastically i.e. with no permanent deformation unless its elastic limit is exceeded. Typical applications include oven door seals where the mesh is behaving as a tubular spring compressed along its length. Plastic energy absorption occurs where the energy absorbed by the mesh structure is dissipated as heat. For example, in bump stops and vibration isolators applications (see also High Resilience).
Resilience can be defined as the ability of a material to absorb energy when deformed and to release that energy on unloading. The feature is particularly beneficial in applications such as seals (often incorporating resilient cores), gaskets and vibration isolators for use in both high and low temperature environments. Our engineers can work with customers to select the materials and manufacturing methods required to configure a product that will perform to the most exacting specifications.
Knitted mesh is used to form an enclosure that acts as Faraday Cage to block electromagnetic fields. This phenomenon is used to screen (protect) sensitive electronic equipment from external radio frequency interference (RFI) and enhance electromagnetic compatibility (EMC). Faraday Cages are also used to enclose devices that produce RFI, such as radio transmitters, to prevent their radio waves from interfering with nearby electronic equipment. These knitted mesh screens can be produced from a wide range of materials including tin-plated copper or copper-plated steel and formed as cooling vents, flexible cable jointing ‘bandages’, and resilient joint seals with elastomer cores for inspection hatches or doors and windows, etc.
Materials can be selected and processed, in any of a huge number of possible variants, to produce knitted mesh components that will withstand the conditions experienced in the most arduous of operational environments. Corrosion resistance and fatigue tests at up to 1,000°C can be conducted on-site with products typically being used in aerospace, automotive, refractory, cryogenic and marine environments.
Encapsulates & Protects
Knitted mesh can be used to encapsulate and protect fragile materials such as the ceramic bricks used in catalyst applications. We also specialise in the ‘over-knitting’ of special materials such as graphite or mica, that are produced to deliver properties against specific customer requirements such as fluid seals or self-lubricating gaskets.
KnitMesh Technologies all-metal resilient wire cores are used in the aerospace and marine industries as well as in high temperature sealing gaskets on furnace and oven doors.
Commercial, military and general aviation aircraft all use wire mesh in their critical systems. For example, our all-metal knitted mesh components provide excellent protection from vibration and shock and can be used wherever adverse environmental conditions would damage or destroy conventional elastomeric or polymeric components. Our knitted mesh has multiple applications within the aviation sector, including filtration for aviation castings, incorporation in composite materials, temperature resilient cores for airframe door, window and hatch seals, support bushings for engine fuel injector pipes as well as a wide range of anti-vibration, electromagnetic compatibility, and electrical screening applications.
We have the capability to knit mesh from virtually any metal, mineral or man-made filament or yarn and then add value further by fabricating in a wide variety of simple or complex shapes and forms to meet specific customer needs. The unique combination of low weight and high tensile strength, coupled with its structural integrity, renders mesh an ideal choice for aviation designers looking for the ultimate in material versatility.
