<p>Provided are: a method for manufacturing a fiber-reinforced resinous vehicular floor structure in which a floor-forming material and a side-forming material of which the transverse cross-section is formed into a closed cross-section are integrated, the side-forming material being created as a pre-molded compact or a preliminary compact, the side-forming material being disposed in a predetermined position inside a mold, a reinforcing fibrous substrate constituting the floor-forming material being disposed inside the mold so as to be in contact with the side-forming material in at least two different surfaces, and a resin being poured into and impregnated in the reinforcing fibrous substrate to integrate, by bonding, the side-forming material and the floor-forming material impregnated with the resin; and a fiber-reinforced resinous vehicular floor structure manufactured by this method. A side portion having a closed cross-section is integrally bonded reliably and firmly with a floor portion, and high mechanical properties can be achieved in the entire fiber-reinforced resinous vehicular floor structure.</p> |
