Abstract

A method for orienting fiber in a matrix, characterized in that it comprises dividing a matrix containing discontinuous fiber and forcing it through a die channel that has internal and external surfaces that diverge from the axis of the die so that the distance of each surface with with respect to said axis it is greater at the channel output than at the channel input and Ao/A1 is 2 or more.
