Spread Tow Technology

NTPT's thin ply prepregs are manufactured using proprietary spread tow technology. This involves the spreading of untwisted fibre tows into thin, flat unidirectional (UD) tapes which are then combined with resin to create pre-impregnated (prepreg) tapes. The evenly distributed, very straight fibres in these spread tow, thin ply prepregs result in composite laminates with a much more uniform microstructure than those produced using conventional multiaxial or woven fabric prepregs.

NTPT's technology enables efficient spreading of all types of fibres in untwisted yarns or tows, including PAN and pitch carbon, glass, aramid, quartz, and other fibres.
