Abstract: Polymeric composite composition including two zones (Z1) and (Z2), at least one zone of the zones (Z1) or (Z2) includes a reinforcing material (RM1), while the other zone of the zones (Z1) or (Z2) includes no reinforcing material or a reinforcing material (RM2) that is different from reinforcing material (RM1). In particular, polymeric composite composition including two zones (Z1) and (Z2) that are in direct contact, at least one zone of the zones (Z1) or (Z2) includes a reinforcing material (RM1), while the other zone of the zones (Z1) or (Z2) includes no reinforcing material or a reinforcing material (RM2) that is different from reinforcing material (RM1). Also, a process for manufacturing such a polymeric composite composition and the use. A process for manufacturing articles in form of mechanical parts or structural elements made of composite material including the polymeric composite composition.

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.
