PURPOSE:To produce a resinous composite material free from voids or air bubbles, densely impregnated with a resin and having good quality and high strength. CONSTITUTION:In the production of a resinous composite material, many fine hollow fibers are arranged in a preform 5 composed of a dry fiber so that the leading end parts of them are dispersed and this preform 5 is introduced into a mold 7 to be impregnated with a resin and, at the same time, the air component enclosed by the inflow resin is discharged through the fine hollow fibers in the preform 5 or the gap between the preform 5 and the mold 7 to perform molding. |
