Abstract: The invention relates to a molding device (1) and a method for the manufacture of structured or semistructured composite components comprising a polymer resin (50) and a fibrous substrate (51). According to the invention, the device comprises a mold (2) comprising a bottom and a lateral surface, a part (10) that is movable along the lateral surface of the mold, comprising a compression surface (14) forming a cavity (7) with the bottom and the lateral surface (5) of said mold (2), characterized in that the movable part (10) comprises a vacuum-drawing channel (13, 23) opening into a chamber (25, 42) located above the cavity and communicating with said cavity (7).

Abstract: The present invention relates to an impregnation process for a fibrous substrate, a liquid composition for implementing this process and the obtained impregnated fibrous substrate. The impregnated fibrous substrate is suitable for manufacturing mechanical or structured parts or articles. In particular the present invention deals with an industrial process for impregnating a fibrous substrate or long fibers with a viscous liquid composition containing mainly methacrylic or acrylic components. This viscous composition is called hereafter liquid (meth) acrylic syrup. The invention concerns also a fibrous substrate pre-impregnated with said syrup which is useful for manufacturing mechanical or structured parts or articles. More particular the impregnation of fibrous substrate with the (meth) acrylic syrup is achieved in a closed mold. The present invention concerns also manufacturing process for manufacturing mechanical or structured parts or articles and three-dimensional mechanical or structured parts obtained by this process.

Abstract: The invention relates to a (meth)acrylic composition comprising:



(a) 100 parts by weight of a liquid (meth)acrylic syrup comprising:

(a1) from 10% by weight to 50% by weight of one or more (meth)acrylic polymers P1, and
(a2) from 50% by weight to 90% by weight of one or more (meth)acrylic monomers M1 comprising only one (meth)acrylic function per monomer,


(b) from 20 parts by weight to 300 parts by weight of a mineral filler C,
(c) from 0.01 part by weight to 5 parts by weight of a (meth)acrylic monomer M2 comprising at least two (meth)acrylic functions per monomer,
(d) from 0.01 part by weight to 5 parts by weight of a (meth)acrylic monomer M3, the monomer M3 being:

either a (meth)acrylic monomer M31 comprising only one (meth)acrylic function per monomer and being different from the monomer(s) M1,
or a (meth)acrylic monomer M32 comprising at least two (meth)acrylic functions per monomer and being different from the monomer M2, and


(e) from 0.01 part by weight to 5 parts by weight of a polymerization initiator.

The invention also relates to a composite material obtained from this (meth)acrylic composition, to a process for manufacturing this composite material and to the uses of the (meth)acrylic composition and of the composite material.
