North Thin ply Technologies

They developed a process to spread reinforcement fibers and make thin Uni-Directional prepreg tapes. A wide range of fibers can be processed (carbon, glass, quartz, aaramid, etc.).They develop in-house developed epoxy or cyanate ester resin systems.

FIBERSThin ply = up to 4 fibres diameters in the prepreg thickness (~18 microns).Use of PAN (Polyacrylonitrile) systems. Fibres use to get standard carbon fibres (starting compound/parent element).Use of Pitch systems. (specific molecular structures). Very high conductivity fibers.

RESINResin quantity = About 38% of the prepreg in mass. Up to 60% if the resin is to be used for other purpose (e.g to fix the prepreg to the core).Tg from 110°C to 300°C.Glue layers up to 15µm seems to be feasible.

COREDevelopment of Carbon cores with an expected mass optimisation of 33%.
