The first ever JEC Forum DACH for the composites industry will be opening its doors on November 23rd in Frankfurt and Technical Fibre Products (TFP), of Burnside, UK,  will exhibit its advanced nonwovens on booth C6. On display will be materials from the Optiveil and Tecnofire ranges.

TFP’s Optiveil nonwovens provide a number of solutions for composites including surface finishing, adhesive carriers or supports, providing fracture toughness improvement or as resin flow media. The latest additions to this range are lightweight veils designed for high temperature performance in composites. They include a polyimide veil, which is the highest temperature stable polymer veil that TFP manufactures, with a maximum service temperature of above 260°C – significantly higher than other polymers such as polyester and PPS. The material was developed as a high performance insulation material for space applications, designed to offer the temperature stability necessary to withstand missions in the direction of Mercury and the Sun, where spacecraft experience extreme temperatures. The other new veil, made from basalt fibre, is stable up to 850°C and retains its integrity when in contact with an open flame. Basalt, like glass, also has a high resistance to acid and alkali, which makes it ideal for use in corrosive environments.

Other Optiveil nonwovebs have been developed specifically for composites, with proven results in aerospace, automotive, sporting goods, marine and energy applications. The veils deliver a high quality resin rich surface, with a dual function of enhancing resin flow and/or adding functionality such as EMI shielding, electrical conductivity, galvanic corrosion protection and abrasion resistance.

TFP’s Tecnofire lightweight intumescent fire protection materials work by expanding from 4 to 35 times their original thickness when exposed to heat, protecting the underlying structure from heat energy. The materials have been specified for use in bridges, fire doors, buses, trains, trams and structural panels following successful fire testing. Specially developed resin infusible grades for incorporation at the surface of a composite provide effective fire protection where it is required, without compromising structural integrity.
