TFP Launch Nonwovens to Improve Composite Fracture Toughness at JEC Europe 2015

Technical Fibre Products (TFP) will be exhibiting their advanced nonwoven materials and new products including an extended range of thermoplastic veils; PPS, PEI, PEEK, polyamide and polyimide at JEC Europe 2015.

According to TFP, the primary use for these veils is in improving the mechanical properties in composites. Business Development Director Adam Black comments that “JEC is an excellent opportunity to introduce the full range of these nonwovens to the international composites market. 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.” A study by the University of Manchester, which discusses the influence of nonwoven veil architectures on interlaminar fracture toughness, will be presented at the show on 10th March, as part of the ‘Mechanical Behaviour of Composites’ section of conference programme.

As well as the new range of thermoplastic veils, TFP will be showcasing an array of products from it’s Optiveil, Optimat and Tecnofire ranges. The Optiveil and Optimat ranges 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 include their potential to act as a resin flow medium, providing enhanced resin transportation in both inter-laminar & surface regions and removing the need to use additional flow media. The ultra-lightweight veils, from 2g/m², are also an effective carrier or support for adhesive films, ensuring a minimum weight addition whilst improving handling and setting the bond line.

Also on display will be TFP’s Tecnofire range of fire protection materials. According to TFP, these materials deliver highly effective passive fire protection at the surface of a composite without compromising the integrity of the structure.

These Optiveil, Optimat and Tecnofire materials are just an indication of TFP’s capability, the development and manufacture of custom nonwovens to meet specific performance, aesthetic or processing requirements is a key part of TFP’s approach. It is recognised that in a lot of cases a standard material will not suffice and in order to a develop a suitable solution for a specific technical challenge TFP have 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.

TFP will be exhibiting in Hall 7.3 on stand C35.
