  • Composite material the characteristics of which can be modulated by preimpregnation of a continuous fiber
    Patent number: 5275883
    Abstract: A composite material the characteristics of which can be modulated by preimpregnation of a continuous fiber.It is characterized in that it is comprised of a sheath and a core consisting of continuous fibers, a powder and a filler the melting temperature of which is higher than at least the highest melting temperature of the other constituents of the material.Applicable notably in the radioelectric fields and to radomes in particular.

  • Apparatus for producing flexible composite material
    Patent number: 4713139
    Abstract: Composite material comprising a flexible sheath covering a roving of fibers impregnated to the core with a finely powdered thermoplastic, the melting point of which thermoplastic is equal to or greater than that of the sheathing material, together with process and apparatus for producing same by using an extrusion coating technique, the coating die being mounted on a leakproof powder fluidization tank via a blowing chamber thermally insulated from the tank.
