Technical Fibre Products (TFP) will be exhibiting several nonwoven developments at composite show CAMX.
The first of these is a nano-functionalized nonwoven, which has been created on TFP’s commercial nanocoating line. The incorporation of nanomaterials such as carbon nanotubes or nanofibers into or onto a nonwoven can provide multiple benefits including improvement of surface conductivity, EMI shielding, thermal management and structural properties, the company says. TFP will also be exhibiting its Tecnofire nonwovens, which provide composites with built in fire protection. Fabricated from high temperature resistant fibers, the resin-infusible materials are incorporated at the surface of a composite, imparting fire protection where it is needed. A new development in this range is a Tecnofire grade which can be activated on demand, without heat. The intumescent mat has been designed for use in a remotely activated fire protection system and, due to the presence of conductive fiber, can also act as an EMI shield.
Another recent development on display will be TFP’s extended range of high performance veils made from thermoplastic fibers, including polyphenylene sulphide (PPS), polyether imide (PEI), Polyether ether ketone (PEEK), polyamide and polyimide. These lightweight materials are designed for use in carbon fiber reinforced plastics (CFRP) as interleaves. The company claims that they can improve mode-I and mode-II fracture toughness, by up to 160% and 430% respectively, whilst adding minimum weight to the final composite part.
