Electrical Conductivity
Tunable and easy to integrate, our nonwovens impart electrical conductivity for composite structures and resistive heating.
Properties
Conductive composites
Imparting function as well as enhancing finish
Our conductive nonwovens are used to impart electrical conductivity to composite parts or component housing. They can be used as supplied or readily incorporated into a composite structure to provide a conductive surfacing layer. Compatible with composite and aircraft assembly techniques, our veils are easy to work with, offering good conformability and resistance to flex fatigue and can be incorporated directly into a composite without additional time-consuming process steps. The level of conductivity is tunable, enabling them to be used in a broad range of applications including conductive tapes or carriers, providing de-icing by resistive heating and the dissipation of static charge.

Applications
Resistive Heating
Our nonwovens have a long track record in enabling resistive or joule heating technologies. The range of conductive nonwovens we offer, coupled with the capability to precisely adapt the electrical properties to deliver a specific level of electrical resistance, make them an ideal candidate for heating applications.
Resistive heating nonwovens work when an electrical current is passed across the structure, when this occurs energy is released in the form of heat. The heat generated is then utilised effectively in a range of different applications including heating panels and de-icing of bridge structures and other components.

Typical Applications
Portable electronics
Our conductive nonwovens can act as conductive tapes and deliver the electrical conductivity necessary for connectors.
Bridges, panels and flooring
Our nonwovens have a long track record in enabling resistive or joule heating technologies, as the electrical resistance of the veil can be adapted to meet the technology requirements. Resistive heating nonwovens work when an electrical current is passed across the structure; when this occurs energy is released in the form of heat. The heat generated is then utilised effectively in a range of different applications including heating panels and de-icing of bridge structures and other components.
Defibrillators
Our conductive nonwovens are used in portable defibrillator pads to ensure the uniform distribution of charge, improving the device effectiveness and preventing electrical burns to the patient.
Mould Heating
Our nonwovens have a long track record in enabling resistive or joule heating technologies. In wind turbine blade manufacture this technology is used in mould heating in order to cure the composite blade structure; conductive nonwovens are incorporated into the mould and heat up when a current is passed through them in order to cure the part.
