Technical Fibre Products (TFP, Burneside, UK) will feature several new products, including an extended range of thermoplastic veils. These include PPS, PEI, PEEK, polyamide and polyimide. The primary use for these veils is to improve the mechanical properties in composites. TFP says the lightweight veils can be interleaved between reinforcement plies to improve the interlaminar toughness of a composite structure, increasing resistance to Mode I and Mode II fracture.
In addition to the new range of thermoplastic veils, TFP showcased an array of products from its Optiveil, Optimat and Tecnofire ranges. The Optiveil and Optimat ranges have been specifically designed to enable a high-quality surface finish while simultaneously imparting surface functionality such as conductivity, EMI shielding and corrosion and abrasion resistance to a composite structure. Other benefits include their potential to act as a resin flow medium, providing enhanced resin transportation in interlaminar and surface regions, removing the need to use additional flow media. The ultra lightweight veils, from 2 g/m2, are also said to be an effective carrier or support for adhesive films, ensuring a minimum weight addition while improving handling and setting the bond line.
