Technical Fibre Products (TFP) will be exhibiting innovative nonwoven solutions for advanced composites at China Composite Expo during September 6-8 alongside their exclusive agents in China, BluDot Asia. The novel multifunctional materials provide solutions for a variety of applications, ranging from aerospace to sporting goods and construction.

TFP's nonwovens are specially designed to fulfill a wide range of applications in advanced composites such as improving performance, properties and fabrication. They are used extensively to provide a high quality resin rich surface finish, particularly in industries such as aerospace, automotive and sporting goods. The exceptional quality of the fibre distribution in the veils makes them ideal for this purpose, producing a smooth surface and ensuring even resin uptake and distribution. A layer of heavier weight Optimat nonwoven can also further reduce print through from the underlying reinforcement fabric if interleaved between the fabric layers close to the surface.

As well as providing a high quality finish, TFP's nonwovens simultaneously impart valuable surface functionality such as EMI shielding, corrosion resistance, abrasion resistance, electrical conductivity and static dissipation, increasing the performance of the composite structure.

Other key performance and property enhancements include improving interlaminar fracture toughness by acting as enhancing interleaves - TFP's lightweight thermoplastic veils significantly improve mode-I and mode-II fracture toughness, by up to 160 per cent and 430 per cent respectively, whilst adding minimum weight to the final composite part, providing a lightweight, effective carrier or support for adhesive films.

TFP's nonwovens also ensure a defined and consistent film thickness whilst improving handling and resilience, preventing galvanic corrosion. TFP's dielectric nonwovens act as an electrically isolating layer between dissimilar conductive materials, such as carbon composite and metal, to prevent the electrochemical reaction that causes galvanic corrosion, acting as a resin flow medium to provide enhanced resin transportation in both inter-laminar and surface regions.

Optiveil and Optimat remove the need to use additional flow media and ultimately lower resin usage and scrap.

TFP's nonwovens also deliver highly effective 'built-in' passive fire protection at the surface of a composite. Tecnofire protects the underlying composite structure from fire and improves the fire smoke toxicity (FST) without the structural compromises or time consuming application associated with alternative technologies.
