CD Tow is composed of two fiber types

1st - Discontinuous tow segments of a structural fiber like carbon, glass or ceramic.

2nd - Continuous axial yarns and an overwrap yarn to allow handling of the CD Tow in textile
operations.  The continuous yarns can be removed after weaving leaving only the
discontinuous textile or they can serve as the matrix precursor of a composite material.
