At JEC Europe 2014, Technical Fibre Products Ltd. (TFP, Burneside Mills, U.K.) and Technical Fibre Products Inc. (Schenectady, N.Y.) showcased their newest Optiveil carbon fiber surfacing veil, which it claims is one of the lightest nonwovens available, at a weight of only 2 g/m2 or 0.1 oz/yd2. The Optiveil product line ranges in weight up to 400 g/m2 and is used for electrical conductivity, EMI shielding, and stabilization for fragile reinforcements and as an adhesive substrate. Other developments include recycled carbon nonwovens and an extended range of lightweight thermoplastic veils — poyetheretherketone (PEEK), polyamide (PA), polyetherimide (PEI) and polyphenylene sulfide (PPS) — that can be incorporated as interlaminar layers in a composite structure to reduce microcracking and, thus, improve fracture toughness.
