Powerful by Nature Ref: TDS- FLAXPLY© – 27 February 2010 - V01 LINEO – FLAX PREPREG PrePreg made of Flax Fibers / Epoxy Resin General information Description LINEO FLAX PREPREG is a range of pre-impregnated material based on an Epoxy Resin system and pre-treated Flax Fibers using the LINEO patented sizing technology. This range of flax prepreg, named FLAXPLY©, has been developed to mainly enhance the vibration absorption qualities of the final composite parts. It also allows the development of greener material. Applications: High performance composite parts • Sporting equipments (bike frames, hockey sticks, tennis rackets, skis, baseball bats) • Marine, especially sailing boats • Transport (body panels, interiors) • Aerospace (secondary parts, interiors) Main Advantages • High Vibration Absorption • Electrical Insulation • CTE near 0 • Low density (1.3) • Tg from 115°C to 150°C depending on curing cycle • Easy and ready to use • Made from natural and renewable resources • Long Shelf life Conact Europe LINEO n.v info@lineo.eu +33 232 431 367 Contact US/Asia LINEO North America benoit@lineo.eu +1 514 531 3453 www.lineo.eu
