Fiber bundle reinforced composite material useful for various high temperature structural members having excellent strength, toughness and resistance to oxidation and a process for producing the same. The fiber bundle reinforced composite material is reinforced with fiber bundles each having a plurality of continuous inorganic fibers bundled with medium such as carbon, being oriented in one, two or three directions, or randomly in the matrix which is reinforced with nano-sized particles precipitated. The fiber bundle reinforced composite material has a desired orientation of fibers and enables production of fiber bundle reinforced composite members having excellent strength and toughness.
