ACCIS CDT industrial seminar: Enhancing composite structures using multifunctional nonwovens

26 April 2017, 4.30 PM - 26 April 2017, 5.30 PM

There is a growing demand in the aerospace and other advanced composite sectors to obtain lightweight, functional materials to enhance a wide range of composite properties such as Fire Resistance, Electromagnetic Interference (EMI) Shielding and composite survivability. This presentation will highlight recent advances in the use of a unique wet-laid process at Technical Fibre Products (TFP) to manufacture multifunctional nonwovens for such applications. For example, an overview of the development of very lightweight nonwovens from high performance thermoplastic fibres for use as ‘enhancing’ interleaves in carbon fibre reinforced plastics (CFRP) will be summarized. Additionally, the development of nonwovens with carefully controlled electrical conductivity will be described and the use of these materials to control composite electrical properties will be outlined using example applications. Finally, a novel electrically conductive, intumescent fire protection mat, which can be readily incorporated into composite structures will be discussed.
