Abstract
A pair of braiding threads 11, 12 and having braiding angle ±θ° to the axis of the mandrel are composed of wide yarns WY having a band shape with a wide width, and the wide yarns are braided around the mandrel without any gap in the width direction to form a cylindrical braiding layer 15 so that the resulting layer is cut in the axis direction of the mandrel to be formed into sheets; thus, a braiding composition backing is formed by these sheets. The objective of the present invention is to provide a braiding composition backing made of thin, uniform braiding layers that are formed by braiding wide yarns having a band shape with a wide width (prepreg slit yarns) around a mandrel without any gap.
