Composite shaping apparatus and composite shaping method

A composite shaping apparatus,

• 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, or presence/absence of rotating power is made different between the at least one first roller and the at least one second roller,
• wherein the at least one first roller comprises a first plurality of subsidiary rollers configured to clamp the prepreg,
• wherein 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 at least one first roller,
• wherein the first plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical third roller that is rotatable about a first axis and two circular disc-shaped fourth rollers that are rotatable respectively about two second axes that are inclined with respect to the first axis, and the third roller and the two fourth rollers are disposed to form a space among the third roller and the fourth rollers, the space corresponding to a cross-sectional shape of a filler to be formed from the prepreg by the composite shaping apparatus,
• wherein the second plurality of subsidiary rollers comprises a cylindrical or hollow cylindrical fifth roller that is rotatable about a third axis and two circular disc-shaped sixth rollers that are rotatable respectively about two fourth axes that are inclined with respect to the third axis, and the fifth roller and the two sixth rollers are disposed to form a space among the fifth roller and the sixth rollers, the space corresponding to the cross-sectional shape of the filler to be formed from the prepreg by the composite shaping apparatus,
• wherein the at least one motor rotates a rotation shaft of the third roller at a first rotation speed, rotation shafts of the fourth rollers at a second rotation speed that is faster than the first rotation speed, a rotation shaft of the fifth roller at a third rotation speed that is slower than the first rotation speed, and
• wherein the sixth rollers are rotatable by friction force produced between the sixth rollers and the prepreg, instead of motive power transmitted from a motor to rotation shafts of the sixth rollers, and
• wherein the at least one first roller and the at least one second roller is configured to rotate so that a tensile force is produced in the filler between the at least one first roller and the at least one second roller.
