    Abstract: PROBLEM TO BE SOLVED: To provide a molding material which gives a molded article having excellent mechanical characteristics, mechanical characteristics in a moisture absorption state, dimensional stability and external appearances without detriment to inherent molding properties, and its manufacturing method. SOLUTION: The pillar-shaped molding material comprises a component (A): a polyamide resin comprising at least (a1) a hexamethylenediamine adipamide unit, (a2) a hexamethylene isophthalamide unit and (a3) a capramide unit, and a component (B): a reinforcing fiber bundle, where the component (B) is arranged nearly parallel with the direction of the axis and has the substantially same length as that of the molding material. The manufacturing method of the molding material comprises the first step; a stranding step where the component (A) is molten and subsequently a continuous component (B) is caused to pass therethrough thereby to give a continuous strand, and the second step; a cutting step where the continuous strand is cooled and subsequently cut to give a pillar-shaped molding material.

    Abstract: PROBLEM TO BE SOLVED: To provide a molding material which can obtain a molded article having well-balanced mechanical properties, particularly impact strength and rigidity and, in addition, has excellent moldability, particularly flowability on molding and high productivity as well, its manufacturing method, and a molded article to be obtained therefrom. SOLUTION: The molding material comprises at least reinforcing fibers and two types of resins (A) and (B), and the resin (A) forms its domain in the matrix of the resin (B) and, simultaneously, has an islands-sea structure having a domain diameter of 0.4-15 mm. Further, the method for manufacturing the molding material comprises previously opening reinforcing fibers, preheating them, and impregnating the bundle of the reinforcing fibers with the resin (A) to form a composite of the reinforcing fibers with the resin (A), then coating the above composite with at least resin (B), and subsequently taking up the coated composite at a rate of >=10 m/min.
