  "abstract": "The heat resisting fiber-reinforced composite material of the invention is a heat-resisting fiber-reinforced composite material used for a product or a part that generates temperature distribution; wherein the thermal expansion coefficient at a portion corresponding to a medium to low temperature range is greater than the thermal expansion coefficient at a portion corresponding to a high temperature range, and the boundary between the portion corresponding to medium to low temperature range and the portion corresponding to the high temperature range is a transition region.",
  "claims": [
    "1. A heat-resisting fiber-reinforced composite material used for a product or a part that generates temperature distribution, comprising: a first portion having a first thermal expansion coefficient corresponding to a medium to low temperature range and; a second portion having a second thermal expansion coefficient being less than the first thermal expansion coefficient corresponding to a high temperature range and laminated to the first portion, wherein a boundary between the first portion corresponding to the medium to low temperature range and the second portion corresponding to the high temperature range is a transition region where facially opposing surfaces of the first and second portions are connected together.",
    "2. A heat-resisting fiber-reinforced composite material used for a product or a part that generates temperature distribution, comprising: a first portion corresponding to a medium to low temperature range is heat-resisting fiber-reinforced glass having a thermal expansion coefficient greater than that of heat-resisting fiber-reinforced ceramics, and a second portion corresponding to a high temperature range is heat-resisting fiber-reinforced ceramics and laminated to the first portion, wherein a boundary between the first portion corresponding to the medium to low temperature range and the second portion corresponding to the high temperature range is a transition region of heat-resisting fiber-reinforced glass and heat-resisting fiber-reinforced ceramics where facially opposing surfaces of the first and second portions are connected together.",
    "3. The heat-resisting fiber-reinforced composite material of claim 1 or 2, wherein the heat-resisting fiber is a ceramic fiber.",
    "4. A method of manufacturing a heat-resisting fiber-reinforced composite material used for a product or a part that generates temperature distribution, wherein a first portion corresponding to a medium to low temperature range is heat-resisting fiber-reinforced glass having a thermal expansion coefficient greater than heat-resisting fiber-reinforced ceramics, a second portion corresponding to a high temperature range being heat-resisting fiber-reinforced ceramics, and a boundary between the first portion corresponding to the medium to low temperature range and the second portion corresponding to the high temperature range is a transition region of heat-resisting fiber-reinforced glass and heat-resisting fiber-reinforced ceramics where facially opposing surfaces of the first and second portions are connected together, comprising the steps of: pre-forming a molding in a desired shape through weaving and subjecting the pre-formed molding to matrix forming treatment in order to obtain a heat-resisting fiber-reinforced composite material in a desired shape.",
    "5. The method of manufacturing a heat-resisting fiber-reinforced composite material of claim 4, wherein weaving of glass fiber and ceramic fiber is performed while properly adjusting the mixing ratios of both fibers.",
    "6. the method of manufacturing a heat-resisting fiber-reinforced composite material of claim 4, wherein weaving of ceramic fiber impregnated with glass powder at a specified ratio is performed."
