20140316063 | THERMOPLASTIC COMPOSITE MATERIAL REINFORCED WITH SYNTHETIC FIBERS AND MANUFACTURING PROCESS - A method for producing a composite material, including an assembly of one or a plurality of synthetic reinforcement fibres, impregnated with at least one thermoplastic polymer having a vitreous transition temperature Tg greater than or equal to 80° C. including: i) a step of impregnating said assembly with a precursor composition in the molten state and including: a) at least one prepolymer P(X)n of said thermoplastic polymer, including a molecular chain P having, at the ends n thereof, identical reactive functions X, said prepolymer having a semi-aromatic and/or semi-cycloaliphatic structure, b) at least one chain extender including two identical functions Y, which are reactive with at least one of said functions X; ii) a step of polymerisation by mass (poly)addition, in the molten state, of said prepolymer with said chain extender, with said thermoplastic polymer of the thermoplastic matrix being the result of said polymerisation by mass polyaddition. | 10-23-2014 |
20150218362 | IMPREGNATION PROCESS FOR A FIBROUS SUBSTRATE, A LIQUID (METH) ACRYLIC SYRUP FOR THE IMPREGNATION PROCESS, ITS METHOD OF POLYMERIZATION AND STRUCTURED ARTICLE OBTAINED THEREOF - 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 mould. 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. | 08-06-2015 |
20150258742 | PROCESS FOR MANUFACTURING A THERMOPLASTIC COMPOSITE PART IN A CLOSED MOULD, WITH INJECTION INTO A COLD MOULD - A process for manufacturing a part made of thermoplastic composite material including a fibrous reinforcement and a matrix of thermoplastic polymer based on a thermoplastic polymer which impregnates said fibrous reinforcement, which process includes: a) a step of impregnating said dry fibrous reinforcement, by injection onto said reinforcement, of a precursor of said polymer, and moulding, with the polymerization step b) being simultaneous with the impregnating and moulding step and with the regulating temperature T2 for said mould being kept constant throughout the moulding cycle, and with reheating of the internal surface of the mould, just before said injection, using a heating means which is external to the mould and removable, with c) demoulding of the part, and d) optional continuation of the polymerization, if said polymerization is partial at demoulding, in a separate step outside the mould, by annealing in an oven at an annealing temperature. | 09-17-2015 |
