VIBRATION CONTROL

AN EVOLUTION IN INHERENT VIBRATION SUPPRESSIVE MATERIALS

We are developing composites that have similar performance as carbon-fibre composites – but with better strength-to-weight ratios.

Using a production process similar to that used in carbon fibre components, we cure multiple layers of graphene-infused polymer, aerogels and other materials into a strong, lightweight material. This provides a higher degree of shock/impact resistance than other composites.

How GC composite technology can be used

For stronger, lighter, more resilient composites

FRICTIONLESS DESIGN

Low friction of the graphene top surface reduces drag

DISPERSING ENERGY

Aerogel provides thermal insulation, whilst the graphene disperses energy due to its high electrical conductivity

DAMPENING VIBRATIONS

Aerogel layers will dampen vibrations

THERMAL PERFORMANCE

Our GC composite will have a significantly lower coefficient of thermal expansion – crucially important in aeronautics

Superior vibration-dampening and strength

The platform technology forming the basis of this technology is easily modified to enable the modulation of a wide range of vibrational frequencies within composite structures.

Our resultant composite structures have been shown to exhibit the strength of an aluminium alloy whilst having the loss co-efficient (the ability to absorb vibration) of an elastomer e.g. polyurethane.

With the added ability to process these materials with standard machining equipment, the new GC range of composite structures under development could be a solution to current materials engineering challenges.

Evolution in Inherent Vibration-Suppressive Materials

In this video, Dr Steve Devine examines the evolution of composite materials for extreme vibration suppression (ballistic events) as developed by GC.

The influence of material properties, such as auxetic structured materials and the addition of graphene-based additives, is discussed and how they influence the final material properties.

The author will also discuss how this technology can be modified to utilise these materials in other market areas. Combining polymeric materials into a composite structure can wield strong, lightweight materials with excellent vibration-damping characteristics without compromising mechanical properties.
