  • Patent number: 10822452
    Abstract: An object of the present invention is to provide a liquid crystal polyester resin composition in which satisfactory fluidity and excellent mechanical properties as well as flame retardancy are obtained, and the generation of particles is suppressed, and a molded article composed of the liquid crystal polyester resin composition. The present invention relates to a liquid crystal polyester resin composition containing: 100 parts by mass of a liquid crystal polyester (A) including repeating units represented by the formulas (I) to (III), wherein Ar1 and Ar2 each represent one or more divalent aromatic groups, and p, q and r each represent a composition ratio (mol %) of each repeating unit in the liquid crystal polyester (A) and satisfy the following conditions, 35?p?90, 5?q?30, and 5?r?30; and 1 to 150 parts by mass of a fibrous titanium oxide (C).
    Type: Grant

  • Patent number: 10711134
    Abstract: A liquid crystal polyester resin composition includes a liquid crystal polyester (A) including repeating units represented by formulae (I) to (III), a liquid crystal polyester (B) including repeating units represented by formulae (IV) and (V), and surface-treated glass fibers (C) including an epoxy resin on the surface thereof, wherein the mass ratio of (A) to (B) [A/B] is from 90/10 to 45/55, the content of (C) is from 10 to 130 parts by mass relative to 100 parts by mass of the total amount of (A) and (B), and as measured in a bending test using a strip-like molded article (length: 127 mm, width: 12.7 mm, thickness: 0.5 mm), the bending strength and the bending elastic modulus of the liquid crystal polyester resin composition are equal to or more than 330 MPa and equal to or more than 20 GPa, respectively.
