The exact composition of the Pro Tour 630/280 is High Modulus Graphite and High Modulus Twaron Fiber. Twaron Fiber is a Aramid Fiber similar to Kevlar. Kevlar was developed by DuPont. But Twaron was developed by the Dutch Company AKZO. In 1989 AKZO changed it's name to Twaron BV. In 2000 Twaron BV is bought by the Teijin Group.

This gives a great description of Twaron Fiber.
