Liquid (meth) acrylic syrups for impregnating fibrous substrates and methods for their production, methods for impregnating fibrous substrates, and composite materials produced after polymerization of this pre-impregnated substrate
The invention relates to a liquid (meth)acrylic syrup for impregnating a fibrous substrate. The invention especially relates to a viscous liquid syrup mainly containing methacrylic or acrylic components. The invention also relates to a method for producing such a syrup. The invention relates further to a process for impregnating a fibrous substrate or long fibers with said viscous liquid syrup. The invention also relates to a fibrous substrate preimpregnated with said syrup, which is useful for the production of mechanical or structured parts or products. The invention also relates to a production method for producing mechanical or structured parts or items and to three-dimensional mechanical or structured parts produced by said method. The invention applies to the production of mechanical parts or structural elements made of impact-resistant thermoplastic composite material.
