A multi-layer fabric is prepared from a chopped glass-fiber strand mat, at least one layer of continuous glass-fiber rovings and a porous tissue-paper backing. The tissue paper is disposed on a first lateral surface of the chopped-strand mat. The roving layer(s) overlay an opposed lateral surface of the mat. The layers are stitch-bonded together to form a complex fabric having advantageous resin wet-out when used as a reinforcement in a composite product.
