Overmolded composite structure

Abstract

The invention relates to an overmolded composite structure comprising: i) a first component (C1) comprising at least one fibrous material and a matrix resin composition, said matrix resin composition comprising at least one polyamide, the at least one polyamide having a number-average molecular weight Mn between 3,000 and 35,000 g/mol, preferably between 5,000 and 20,000 g/mol, preferably between 5,000 and 15,000 g/mol, preferably between 5,000 and 10,000 g/mol, and a melt viscosity, measured as capillary rheology, measured at Tf +50° C., Tf being the melting temperature of the at least one polyamide, at a shear rate of 1800 s−1, between 0.05 and 1000 Pa·s, preferably between 0.1 and 1000 Pa·s, preferably between 0.3 and 1000 Pa·s, preferably between 0.3 and 500 Pa·s, more preferably between 0.3 and 250 Pa·s, for example between 0.3 and 100 Pa·s, even more preferably between 0.3 and 50 Pa·s, more preferably between 0.3 and 25 Pa·s, even more preferably between 0.3 and 10 Pa·s, preferably between 0.3 and 5 Pa·s; and ii) a second component (C2) comprising an overmolding resin composition, the first component C1 having at least one surface S, and component C2 adhering to component C1 on at least part of surface S.
