COMPOSITE MATERIAL OF A CONTINUOUS THERMOPLASTIC SHEATH AND OF A CORE WHICH IS SENSITIVE TO THE FUSION TEMPERATURE OF THE SHEATH AND A PROCESS FOR PRODUCING IT

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.
