A composite shaping apparatus (1B; 1C; 1D; 1E) comprising: at least one first roller configured to load a prepreg with pressure; at least one second roller configured to load the prepreg with pressure; and at least one motor configured to rotate at least one of the at least one first roller or the at least one second roller, wherein the at least one first roller and the at least one second roller are rotated while at least one of rotation speed, roller diameter, or presence/absence of rotating power is made different between the at least one first roller and the at least one second roller in order to control the speed of the outer surface thereof in contact with the filler; the at least one first roller comprises a first plurality of subsidiary rollers configured to clamp the prepreg; the at least one second roller comprises a second plurality of subsidiary rollers that clamp the prepreg at a position different from a clamping position of the first roller; the first plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical third roller (2A_1) that is rotatable about a first axis and two circular disc-shaped fourth rollers (2B_1, 2C_1) that are rotatable respectively about two second axes (AX2, AX3) that are inclined with respect to the first axis, and the third roller (2A_1) and the two fourth rollers (2B_1, 2C_1) are disposed so that a space that corresponds to a cross-sectional shape of a filler is formed between the third roller (2A_1) and the fourth rollers (2B_1, 2C_1); and the second plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical fifth roller (2A_2) that is rotatable about a third axis and two circular disc-shaped sixth rollers (2B_2, 2C_2) that are rotatable respectively about two fourth axes (AX2, AX3) that are inclined with respect to the third axis, and the fifth roller (2A_2) and the two sixth rollers (2B_2, 2C_2) are disposed so that a space that corresponds to a cross-sectional shape of the filler is formed between the fifth roller (2A_2) and the sixth rollers (2B_2, 2C_2). at least one first roller configured to load a prepreg with pressure; at least one second roller configured to load the prepreg with pressure; and at least one motor configured to rotate at least one of the at least one first roller or the at least one second roller, wherein the at least one first roller and the at least one second roller are rotated while at least one of rotation speed, roller diameter, or presence/absence of rotating power is made different between the at least one first roller and the at least one second roller in order to control the speed of the outer surface thereof in contact with the filler; the at least one first roller comprises a first plurality of subsidiary rollers configured to clamp the prepreg; the at least one second roller comprises a second plurality of subsidiary rollers that clamp the prepreg at a position different from a clamping position of the first roller; the first plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical third roller (2A_1) that is rotatable about a first axis and two circular disc-shaped fourth rollers (2B_1, 2C_1) that are rotatable respectively about two second axes (AX2, AX3) that are inclined with respect to the first axis, and the third roller (2A_1) and the two fourth rollers (2B_1, 2C_1) are disposed so that a space that corresponds to a cross-sectional shape of a filler is formed between the third roller (2A_1) and the fourth rollers (2B_1, 2C_1); and the second plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical fifth roller (2A_2) that is rotatable about a third axis and two circular disc-shaped sixth rollers (2B_2, 2C_2) that are rotatable respectively about two fourth axes (AX2, AX3) that are inclined with respect to the third axis, and the fifth roller (2A_2) and the two sixth rollers (2B_2, 2C_2) are disposed so that a space that corresponds to a cross-sectional shape of the filler is formed between the fifth roller (2A_2) and the sixth rollers (2B_2, 2C_2).
