PURPOSE:To suppress the occurrence of the crack or residual stress of shapes, by providing the spraying mechanism of an abrasive material between the exit of a die and a driving mechanism, and by controlling a fluid containing the abrasive material to preset temperature. CONSTITUTION:There are provided a heated hot die 14 for executing the removing of excessive resin from a fibrous assembly, the shaping of outer shape and the hardening of resin, and a spraying mechanism 16 of an abrasive material for spraying fluid containing the abrasive material controlled to a preset temperature to the surface of a shapes 15 which is set up between the exit of this hot die 14 and a driving mechanism 17. The temperature of the hot die 14 is controlled as having a temperature gradient of 100 deg.C near the inlet and 170 deg.C at the latter half section. Therefore the temperature of the shapes 15 becomes about 160 deg.C just after passing through the hot die 14. This high-temperature shapes 15 passes through the spraying mechanism 16 of the abrasive material, and is sprayed by high-pressure air with a particulate abrasive material, for example an alumina. Thereby it is possible to prevent the internal crack or residual stress, and to simultaneously execute the removal of flash and the abrasive finishing of the surface of the shapes 15. |
