    • A method for producing a prepreg, includes: preparing a reinforcing fiber sheet containing multiple reinforcing fiber bundles, a matrix resin composition, first and second release sheets, and elastic members; forming a prepreg precursor by providing the matrix resin composition on the reinforcing fiber sheet; sandwiching the prepreg precursor between the first and second release sheets so that first surfaces of the first and second release sheets make contact with the prepreg precursor and that the first and second release sheets respectively include extended portions that protrude outward from both edges of the prepreg precursor in a width direction; positioning the elastic members to face the extended portions of the second release sheet and to make contact with the second surface of the second release sheet; and compressing the prepreg precursor, first and second release sheets and the elastic members all at once in a thickness direction of the prepreg precursor.
    • 一种预浸料坯的制造方法,其特征在于,包括:制备含有多个增强纤维束的增强纤维片,基质树脂组合物,第一剥离片和第二剥离片,以及弹性部件。 通过在增强纤维片上设置基质树脂组合物形成预浸料坯前体; 将预浸料坯前体夹在第一和第二剥离片之间,使得第一和第二剥离片的第一表面与预浸料坯前体接触,并且第一和第二剥离片分别包括从预浸料坯前体的两个边缘向外突出的延伸部分 在宽度方向; 将弹性构件定位成与第二剥离片的延伸部分相对并与第二剥离片的第二表面接触; 并且在预浸料坯前体的厚度方向上一次压缩预浸料坯前体,第一和第二剥离片和弹性构件。
