  • Patent number: 7664564
    Abstract: A setting area is stored in association with the external shape of a knitted fabric, and the setting area is altered as the external shape is altered. A unit pattern is vertically copied repeatedly in the setting area. When setting patterns exist on both sides of the boundary between front and rear knitted fabrics, the boundary being a start point of circumferential formation, the setting pattern on the start section side is shifted upward by one course. The range for providing the setting pattern therein can be altered automatically when the external shape of the knitted fabric is altered. Furthermore, the setting pattern does not become discontinuous in a course direction at the boundary between the front and rear knitted fabrics.

  • Patent number: 6596373
    Abstract: The present invention relates to an epoxy resin composition for a fibre reinforced composite material, which is thermosetting resin composition where the glass transition temperature Tg of the cured material obtained by heating for 2 hours at 180° C. is at least 150° C., and the modulus of rigidity G′R in the rubbery plateau in the temperature region above the aforesaid Tg is no more than 10 MPa. In accordance with the present invention, it is possible to provide a fibre-reinforced composite material which is outstanding in its resistance to hot-wet environmental condition, impact resistance, and strength characteristics such as tensile strength and compression strength, and furthermore it is possible to provide a thermosetting resin composition and a prepreg outstanding in terms of their peel strength to a honeycomb core.
