  • METHOD FOR IMPREGNATING A FIBROUS SUBSTRATE WITH A (METH)ACRYLIC MIXTURE, COMPOSITION OF SAID (METH)ACRYLIC MIXTURE, AND COMPOSITE MATERIAL PRODUCED AFTER POLYMERISATION OF SAID (METH)ACRYLIC MIXTURE
    Publication number: 20180002503
    Abstract: The present invention relates to a process for impregnating a fibrous substrate consisting of long fibers by a liquid (meth)acrylic mixture mainly containing methacrylic and/or acrylic components. The invention also relates to such a (meth)acrylic mixture and its composition, said (meth)acrylic mixture comprising a (meth)acrylic syrup and an aqueous dispersion of radical initiator. The invention also relates to a process for manufacturing mechanical parts or structured elements or articles made of composite material by impregnating the fibrous substrate with the (meth)acrylic mixture then polymerizing said (meth)acrylic mixture, and also such parts obtained according to said manufacturing process and used in varied fields such as the automotive industry, aeronautics, or else construction.
