CTG: Crompton Technology Group

What we do

Based in a brand new 137,000 square foot Composite Centre of Excellence, CTG has a fully flexible production capability, ranging from one-off problem-solving and bespoke projects to meet specific customer requirements, to volume manufacturing. Its design, development, and testing facilities allow for new techniques and concepts to be created and fully tested in-house to ensure products meet the highest quality standards. The company has ISO 9001, AS 9100, and ISO 14001 accreditations for its quality and environmental management.

Collins Aerospace designs, manufactures and services integrated systems and components for the aerospace and defense industries. For further information on Collins Aerospace go to:

Fluid Transfer

Fluid Transfer

Composite pipes and tubes for aerospace fluid transfer are fitted within the aircraft fuel and hydraulic systems to prevent the effect of a lightning strike, while still facilitating dissipation of a static charge. CTG has developed a robust method of joining the composite tube/pipe with various metal fittings. The composite pipes and tubes allows the precise tuning of electrical resistivity and fly on aircraft today.



CTG’s structural technology can transfer load in several different conditions with a number of joining solutions. One of the composite to metallic interfaces is designed to be pre-loaded, resulting in a fatigue proof component and can withstand large loads up to >1000KN. Others rely on a similar joint to the transmission shafts providing a lower costs and weight solution. Depending upon the application, these components are structurally designed to resist compression, tension, bending and torque loads.



CTG realised that the aerospace market would not favour reliance upon adhesives joining the metal flange to the composite structure. Therefore the company developed a patented composite to metal interface which allows the reliable transfer of torque with zero reliance upon adhesives, reducing risk of failure. CTG has also developed other elements for a transmission shaft system, including universal joints and TORQdisc couplings; these further contribute to part reduction and weight savings.



CTG's composite products are exceptionally strong, long-lasting, lightweight and, in many applications, require little maintenance. As an alternative to metals and alloys, they can deliver significant operating cost savings, reduce energy use and carbon emissions, and open up new possibilities in design by being easier to form into complex shapes, without compromising strength or durability.
