Wholly aromatic polyester fiber-reinforced high performance thermoplastic and process for preparing same. Self-reinforced polymer composites of 60-5% by weight of an at least partially crystalline high performance thermoplastic polymer and 40-95% by weight of a melt processable wholly aromatic polyester which exhibit anisotropic properties in the melt phase. This wholly aromatic polyester is a liquid crystal polymer... The wholly aromatic polyester is in the form of... unidirectionally oriented continuous fibers, primarily in the range of about 1 to 10 micrometers in diameter, distributed in a matrix of polyether etherketone. The polymer composites of this invention have high tensile strength, high modulus, satisfactory elongation, good impact strength, good flame resistance, good high temperature properties, and good electrical properties which remain stable over a wide range of temperatures and frequencies.  1, record 2, English, - wholly%20aromatic%20polyester

Viewed with the microscope set up as a conoscope, the images of anisotropic crystals as seen with the orthoscope are supplanted by highly informative patterns of interference colors called "interference figures. "These are formed by rays that traveled along different directions while within the crystal being viewed.  1, record 3, English, - interference%20figure
