Let’s reimagine aerospace
Lightweight, strong, and carbon-negative at scale
The aerospace industry has long faced the challenge of how to build the most lightweight aircraft. But what if lightweight also came with superior strength, carbon-negative benefits at scale, as well as the security that comes with a material that is abundant and recyclable–hello, circular supply chain!
Galvorn’s properties make it suitable for cabling and wiring applications where light weight, strength, and durability are critical. Not every application requires the 58 MS/m conductivity of copper, for example, as cable shielding or conductors in twisted shielded pair cables. Galvorn CNT shielded cables are at least 40 - 60% lighter than commercial cables and have comparable shielding performance. Galvorn CNT wire is up to 90% lighter than copper wire with significantly better resistance to flex fatigue: Galvorn wire has over 100x longer flex life than the same diameter copper wire.
Electromagnetic interactions in aerospace electrical systems are of growing concern due to the increasing susceptibility of system components to electromagnetic interference (EMI). Galvorn CNT film is flexible and conductive, and can provide lightweight EMI shielding for both cables and enclosures. Galvorn has demonstrated its ability to act as a faraday cage, blocking calls and other signals from reaching a smartphone wrapped in just two layers of 50 μm thick CNT film.
Did you know
Copper wiring makes up as much as one-third of the weight of a 15-ton satellite
Half of this wire weight is typically in the EMI shielding. Wiring and connectors are particularly vulnerable to electromagnetic interference. Historically there’s been a significant trade off between EMI shielding effectiveness and weight. By substituting products that offer comparable shielding effectiveness customers can achieve dramatic results in weight-savings with minimal insertion risk to the application.
Did you know
Galvorn is 6x stronger, 6x less dense, and has >25x higher flex life than copper
This is a winning combination for conductors in aerospace applications. Left: a standard copper braid cable shield compared to a Galvorn CNT shield for an RG-316 cable. Galvorn CNT film shields are 95% lighter than the copper double braid shields, while offering comparable shielding effectiveness and insertion loss properties.
Did you know
But wait, there’s more...
Galvorn RG-316 CNT film shielded cables also have the following advantages :
- Overall cable weight reduction of CNT shielded vs. Cu double braid shielded cable without connectors is over 50%
- CNT film shield is 100 microns thick compared to 500 micron thick Cu double braid shield
- It is easy to apply CNT film to coaxial cables as well as twisted pair type cables
- CNT film shielded cables survive at least 1000 flex cycles with a minimum bend radius of at least 7.5X the jacketed cable diameter
Today composite materials are providing a lightweight alternative for aircraft wings, but they still rely on metals for lightning strike protection. With its combined conductivity, lightweightness, and strength Galvorn has the potential to not only solve for this critical aerospace tradeoff, but simultaneously minimize environmental impact.
