The present invention provides a mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The mat includes a primary, supporting layer having a plurality of randomly oriented essentially continuous glass fiber strands. The primary layer has about 1 to about 10 weight percent of the mat on a total solids basis. The mat also includes a secondary layer positioned upon and supported by a surface of the primary layer, the secondary layer including a plurality of glass fiber strands. The mean average length of the glass fiber strands of the secondary layer ranges from about 20 to about 125 millimeters. The strands of the primary layer are entangled with the strands of the secondary layer by needling the primary layer and the secondary layer together.

L'invention concerne un mat conçu pour renforcer une matière matricielle thermodurcissable pour former un composite, des composites constitués de la sorte, et des procédés correspondants. Le mat comporte une couche de support primaire présentant une pluralité de faisceaux de fibres de verre essentiellement continus et orientés de manière aléatoire. La couche primaire représente, en poids, de 1 % environ à 10 % environ du mat, sur une base de solides totaux. Le mat comprend aussi une couche secondaire disposée sur la couche primaire, portée par une surface de celle-ci et comprenant une pluralité de faisceaux en fibres de verre. La longueur moyenne des faisceaux de la couche secondaire oscille entre 20 mm environ et 125 mm environ. Les faisceaux de la couche primaire sont enchevêtrés avec ceux de la couche secondaire par aiguilletage des deux couches en question.
