Composite material composed of a continuous thermoplastic jacket and of a core being sensitive to the fusion temperature of the jacket, and method of manufacturing the composite material

摘要

1. A composite material constituted by a continuous thermoplastic sheath and a core chosen from compounds of which the melting point, or in default of this the decomposition temperature, is below the melting point of the sheath, characterized in that the core is at least partially in the form of a powder.
