Advanced nonwovens at China Composites Expo

 TFP’s nonwovens are specially designed to fulfil a wide range of applications in advanced composites, 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. Technical Fibre Products (TFP) will be exhibiting its innovative nonwoven solutions for advanced composites at the forthcoming China Composites Expo which takes place in Shanghai from 6-8 September. The UK company’s novel multifunctional materials provide solutions for a variety of challenging applications, ranging from aerospace to sporting goods and construction.

TFP’s nonwovens are specially designed to fulfil a wide range of applications in advanced composites, 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, 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,” the company says.

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, according to the company.

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 % and 430 % respectively, whilst adding minimum weight to the final composite part, TFP explains.

They are also used for providing a lightweight, effective carrier or support for adhesive films, ensuring a defined and consistent film thickness whilst improving handling and resilience. Other applications include 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 is an additional application. Optiveil and Optimat remove the need to use additional flow media and ultimately lower resin usage and scrap.

Delivering highly effective ‘built-in’ passive fire protection at the surface of a composite is another application. 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.
