Why Choose
Carbon Hinge

01
No metal = no rust
Carbon fibre and Kevlar aramid are resistant to the harshest conditions. Saltwater and UV kill all metal hinges over time — not carbon hinge, because there is no metal to corrode and no coating to maintain.
1,000 hr ASTM B117 salt spray — zero mass change
02
Co-moulding with a composite structure
Carbon Hinge can be laid into a CFRP layup and cured in the same autoclave cycle as the panel itself. The result is a monolithic composite structure with no bond line, no fasteners and no stress concentration from hardware. No metal hinge can do this.
Co-cure compatible — same cure cycle as standard CFRP prepreg
03
Cost is comparable to stainless
The price of Carbon Hinge is in line with 316 stainless marine-grade piano hinge. Engineers switching from metal get better corrosion resistance, lower weight and zero galvanic interface with no cost premium. The upgrade costs nothing.
≈ 316 stainless marine-grade pricing · No composite premium
04
Non-magnetic, no galvanic and No RF interference
All of our hinges contain no metal, meaning they are completely free of magnetic signatures. We are also able to provide options that can suit a variety of applications to adhere to galvanic and Radio Frequency needs.
No application is too exotic — Carbon Hinge can do it all

FAQ

Frequently
asked questions

Hinge wings are produced in a range of thicknesses. The overall strength of the hinge is determined more by the number of Kevlar layers than by the thickness itself. Hinges under 3mm are intended for bond only installation, while hinges 3mm and above can be installed using countersunk screws.
Our website lists hinges up to 2.2 metres, but we have also produced custom hinges as long as 6 metres. Hinges can be supplied cut to length, typically with a ±1mm tolerance.
A standard hinge contains one Kevlar layer. Heavy duty versions use two layers, and we have produced custom designs with up to five. As the number of layers increases, the hinge becomes stronger but its available rotation decreases.
With no metal components, the hinge is highly resistant to corrosion. Kevlar can degrade under UV exposure, so all hinges are coated with a flexible black UV protective layer. For applications exposed to extreme UV conditions, we recommend testing to confirm suitability.
The hinge has been cycle tested to one million cycles. After testing, only a slight increase in Z axis flexibility was observed.
Each hinge is supplied with a peel ply surface on one side. This provides an excellent bonding surface and requires no additional preparation. For critical installations, the peel ply can be left attached for removal on site.
Yes. We produce a wide range of custom hinge configurations. Wings can be made larger, smaller, or asymmetrical, and we can mould complex shapes directly into the carbon fibre. Where galvanic isolation or RF transparency is required, we can produce all glass hinges.
For cutting, fine tooth metal cutting blades work best; hacksaws and band saws are ideal. For drilling, a standard twist drill is suitable, though tungsten carbide drills are recommended for repeated or high volume work. Cutting through the Kevlar layer may leave a soft, furry edge — this is normal. It can be trimmed cleanly with a very sharp knife. Avoid carbon dust and ALWAYS use appropriate PPE.
