PURPOSE:To provide a rod material by enhancing handling properties in the case of winding a sticky prepreg in a cylindrical form, at the same time, possibly simplifying the working process of winding a polyester tape thereon after the winding of prepreg, and arranging a surface with high smoothness on the outer peripheral surface on the gentle conical surface. CONSTITUTION:A lamination 9 is formed of prepreg 4 consisting of reinforcement fiber 2 and resin 3, and a forming polyester tape 6 by superimposing them in almost the same width, and then it is wound spirally around a rod along its axial direction, and respective parts of the lamination adjoining in the rod axial direction of the lamination 9 are made into an adjoining state, viz., side ends of respective parts of the lamination are in contact with each other. |
