  • Patent number: 9567462
    Abstract: The present invention relates to reinforced polyamide molding materials with high notch impact strengths, comprising low viscous polyamides and flat glass fibers as a reinforcing medium, characterized in a polyamide matrix, comprising the following components: (A) 0 to 60 wt.-% of at least one aliphatic, partly crystalline polyamide with a solution viscosity, measured in m-cresol (0.5 wt-%), of ?rel less than 1.9, (B) 0 to 60 wt.-% of at least one amorphous or microcrystalline polyamide based on aliphatic, cycloaliphatic or aromatic diamines, dicarboxylic acids, lactams and/or aminocarboxylic acids, preferably with 6 to 36 carbon atoms, or a mixture of such homopolyamides and/or copolyamides, wherein the components (A) and (B) fulfill the condition: (A)+(B)=20 to 60 wt.-% and that, in the case of a mixture of components (A) and (B), at least 50 weight parts aliphatic blocks (A) are present in the mixture, and a filler component, comprising: (C) 40 to 80 wt.

  • Patent number: 6842574
    Abstract: The car industry increasingly uses plastic optical fibers whose protective sheathing (4) is made of a polyamide. As unmodified PA poorly adheres to the fluoropolymers often used as the material for the fiber cladding (3), the plastic optical fiber (2, 3) moves in relation to the protective sheathing (4) when the temperature varies. To suppress this effect referred to as “pistoning”, the connectors and holders of the optical fibers must apply very large clamping forces to the protective sheathing (4) and the plastic optical fiber (2, 3) arranged therein, resulting in an increased signal attenuation. The use of a modified PA can clearly improve the adherence of the protective sheathing (4) to the cladding (3) of a plastic optical fiber which is made of a fluoropolymer.
