Abstract: PURPOSE:To prevent the extreme lowering in the strength of a composite material caused by delamination, by a method wherein at least three kinds of strip like prepregs mutually different in a winding angle are wound around a mandrel so that an intersecting point crossing at one point is generated at a large number of areas to complete first winding work and winding works on and after the second stage are subsequently performed while the positions of intersecting points are shifted and the formed cylindrical prepreg is opened by cutting to be formed into a flat plate before curing. CONSTITUTION:The strip like prepreg 7 drawn out from a bobbin 6 is once reciprocally wound around the outer peripheral surface of a mandrel 5 at a winding angle of + or -45 deg.. Subsequently, the strip like prepreg 7 is once wound around the mandrel 5 from the start end thereof in the axial direction to the final end thereof at a winding angle near to 90 deg., for example, 80 deg.. After the first winding work was completed, a winding position is shifted and the strip like prepreg 7 is once reciprocally wound around the mandrel 5 at a winding angle + or -45 deg. and, thereafter, the winding position is shifted to once wind the strip like prepreg 7 around the mandrel 5 at a winding angle of 90 deg. in the axial direction. Subsequently, winding works on and after the second stage are successively performed while the positions of intersecting points are shifted. After the winding works of predetermined stages were completed, the cylindrical prepreg is pulled off from the mandrel 5 and opened by cutting to be formed into a flat plate which is, in turn, cured to form a composite material plate body.
