(JP9170138-A)       A triaxial fabric of fabric weight (metsuke) 40-75 g/m3 is made from an optical anisotropic pitch as raw material, which has a tensile elastic modulus of 35-60 tf/mm2 , tensile strength 300 kgf/mm2, tensile breakage stretchability 0.6%, fibre diameter 7.0 m, and additionally is constituted by or using a bundle of fibres with thermal conductivity in the fibre axis direction of the carbon fibre of 80 W/mk and yarn size 40-75 g/km. Also claimed is a process for producing the 3-axis fabric which is woven from a basic system with cloth density of 9.25 bundles/inch.    USE -   The triaxial fabric is especially used as the skin material of honeycomb panel like antennae and solar cells in space structures including satellites.    ADVANTAGE -   The material is simple to make and has light weight, as well as high elastic modulus, tensile strength and thermal conductivity, and extremely small thermal expansion coefficient, with no need for laminating, and little peeling of the layers.
