The present invention relates to a (meth)acrylic mixture for impregnating a fibrous substrate, characterized in that it comprises: a) a first dispersion comprising at least one (meth)acrylic polymer obtained by emulsion polymerization of one or more (meth)acrylic monomers, b) a second dispersion comprising at least one flame retardant. The invention also relates to a method for impregnating a fibrous substrate with a (meth)acrylic mixture of this kind, and to a method for manufacturing mechanical parts or structured elements, or articles, from the (meth)acrylic mixture. Another objective of the invention is a mechanical part or a structured element or an article made of composite material, obtained by the implementation of the manufacturing method.

A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an aldehyde or ketone and an amine salt of an inorganic acid. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.
