摘要 |
A method of making a microsphere-filled wet-laid veil involves forming a non-woven fibrous veil, contacting the veil with an impregnation binder composition having a binder and microspheres, and impregnating the microspheres of the impregnation binder composition into the veil to form a microsphere-filled wet-laid veil. The microsphere-filled wet-laid veils produced according to the method of the present invention are useful to make molded composite articles.
