North Thin Ply Technology (NTPT, Penthalaz-Cossonay, Switzerland) has developed a unidirectional prepreg tape with an areal weight of only 15 gsm, producing what is possibly the thinnest prepreg tape on the market. NTPT achieved this by spreading an intermediate modulus carbon fiber and adding the high Tg epoxy resin ThinPreg 120EPHTg – 402. This prepreg can be used to create lightweight sandwich panels to be used for ultralight aircrafts, UAVs, other aerospace applications and rigid wings for racing yachts.
