Abstract
Linerless prepreg, composite articles therefrom, and related methods are disclosed. In linerless prepreg according to the invention, matrix material is impregnated into a reinforcement material without the need for any release liners during manufacture or storage thereof. Beneficially, prepreg of the invention is capable of being easily wound into a roll or stacked for storage, without sticking to itself when it is later used in the manufacture of composite articles.
