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 present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least three initiators. In particular the present invention relates to a liquid composition comprising a monomer, a (meth)acrylic polymer and at least three initiators that have a different half life time. That liquid composition can be used as a syrup and especially as a syrup for impregnation of fibres or fibrous material. Also concerned is a thermoplastic material obtained after polymerization of the liquid composition. The invention also relates to a process for manufacturing such a liquid composition. The invention also relates to a process for impregnating a fibrous substrate of long fibres with said liquid composition. The invention also relates to a fibrous substrate impregnated with said liquid composition which is useful for manufacturing composite parts. The present invention also relates to a process for manufacturing mechanical parts or structural elements made of composite material and to mechanical parts or structural elements made of composite material obtained via a process using such a liquid composition.

Abstract: The present invention relates to a (meth)acrylic composition suitable for (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites, its method of preparation, its use and obtained (meth)acrylic polymeric compositions and (meth)acrylic polymeric composites. In particular the present invention relates to a (meth)acrylic composition that is crosslinked once polymerized and that is suitable for (meth)acrylic composites and more particular for reinforcing elements or fibre reinforced polymer (FRP) rebars. More particularly the present invention relates to a (meth)acrylic composition suitable for producing reinforcing elements or FRP rebars, preparing such a (meth)acrylic composition, composite reinforcing elements or rebar comprising it after polymerization and method of preparing such a composite reinforcing elements or FRP rebar. The present invention also relates also to the use of such a (meth)acrylic composition and the use of reinforcing elements or FRP rebars for concrete.
