Abstract (en)
[origin: CA2971543A1] The invention relates to a method for impregnating a fibrous substrate consisting of long fibres with a liquid (meth)acrylic mixture mainly containing methacrylic and/or acrylic components. The invention also relates to such a (meth)acrylic mixture and the composition thereof, said (meth)acrylic mixture comprising a (meth)acrylic syrup and an aqueous dispersion of a radical initiator. The invention further relates to a method for producing mechanical parts of structured elements or items in a composite material by impregnation of the fibrous substrate with the (meth)acrylic mixture followed by polymerisation of said (meth)acrylic mixture, and to such parts produced according to said production method and used in different fields such as the automobile, aeronautics or construction industries.
