Abstract
The embodiments are directed to a method and apparatus for preferably producing a two layer off-axis composite prepreg material in tape form that has fiber direction at angles such as plus or minus five degrees to the longitudinal direction of the backing paper. The use of such off-axis prepreg composite material tape is primarily for fabricating high length-to-width ration parts such as composite wing stringers or spars for aircraft.
