Technical Fibre Products (TFP) will be showcasing products from their Optiveil, Optimat and Tecnofire ranges at Composites Europe, including the new, extended range of high performance thermoplastic veils; including PPS, PEI, PEEK, polyamide and polyimide.
According to TFP, these materials have been developed specifically to significantly improve the mechanical properties of a composite with minimal modifications to the manufacturing process necessary. The lightweight veils can be interleaved between reinforcement plies to provide a means to significantly improve the interlaminar toughness of a composite structure, increasing resistance to both mode-I and mode-II fracture.
TPF says that the full range of Optiveil and Optimat materials, of which the thermoplastics are just a part, have been specifically designed to provide multiple benefits; enabling a high quality surface finish whilst simultaneously imparting surface functionality such as conductivity, EMI shielding and corrosion & abrasion resistance to a composite structure. Other benefits described include the use of dielectric nonwovens to prevent galvanic corrosion, which occurs when aluminium or other metals come into contact with carbon fibre in a composite structure. The nonwoven provides an extremely uniform, lightweight barrier between the two materials to isolate them, stopping an electrochemical reaction occurring. In addition, the ultra lightweight veils, from 2 g/m², are an effective carrier or support for adhesive films, ensuring a minimum weight addition whilst improving handling and setting the bond line.
TFP’s Tecnofire range of fire protection materials will also be on display. TFP claims that these materials deliver highly effective passive fire protection at the surface of a composite without compromising the integrity of the structure.
The Optiveil, Optimat and Tecnofire materials are just an indication of their capability, explains TFP; the development and manufacture of custom nonwovens to meet specific performance, aesthetic or processing requirements is a key part of its approach. It says it is recognised that in a lot of cases a standard material will not suffice and in order to develop a suitable solution for a specific technical challenge TFP has extensive experience and product development facilities. The latter include a pilot machine, high spec laminator, fibre coating line and nanocoating facility, all of which help to enable both effective material design and scale up from concept to larger scale production.
Technical Fibre Products will be exhibiting in Hall 5, Stand G18.
