PURPOSE:To sufficiently infiltrate a resin to the center of a supplied bundle of fibers to pultrusion mold a fiber reinforced resin product superior in strength by a method wherein a thermosetting resin is injected from two points, and the resin is pultrusion molded while a negative pressure is applied between the two points. CONSTITUTION:A pultrusion mold 1 is provided with a hollow 2 restricting a cross sectional shape of a product. In this pultrusion mold 1, a plurality of resin stagnant parts 5, 5 each connecting to a resin injection port 4 are provided in the vicinity of an insertion port 3. A vacuum cavity part 7 is provided between the resin stangant parts 5, 5 through throttle parts 6, 6. A pressure reducing device 8, such as a compressor, is connected to the vacuum cavity part 7. In this embodiment, resin stagnant parts 5 are provided at two points. However, this invention is limited to this embodiment, but resin stagnant parts 5 can be provided at three points or more with two or more vacuum cavity parts 7 provided between through throttle parts 6. |
