Here, the steel blank may be made of a steel material having strength of 980PMa or less. The prepreg patch is a patch made of a composite material preliminarily impregnated with a resin. The prepreg may be a CFRP (Carbon Fiber Reinforced Plastics) prepreg.

The prepreg patches may be spaced on the steel blank at a smaller size than the steel blank. In this state, the prepreg patches can be partly joined to the steel blank by partially heating to about 50 캜.

Thereafter, the steel blank to which the prepreg patches are bonded is produced by simultaneously molding a side seal by a hot press method. At this time, the steel blank to which the prepreg patches are bonded is supplied to the hot press die. Thereafter, the prepreg patches and the steel blank are pressurized and heated at the same time to form the side seals 110, followed by cooling and curing. At this time, the prepreg patches can be joined to the steel blank when they are melted, cooled, and cured, so that the prepreg patches can be joined to the steel blank to form a part of the side seal 110 without a separate adhesive.

The side seal 110 thus manufactured may have a structure in which the portion 111 formed by the steel blank is resistant to impact and the portion 112 formed by the prepreg patches can absorb the impact. Therefore, compared with the case where the side seal 110 is manufactured by the hot stamping or the roll forming method, the shock absorbing ability can be improved. The side seal 110 may be manufactured by a method of manufacturing a center pillar 120 or a front filler upper 140 to be described later.
