Abstract
A prepreg tape is firstly prepared by bonding prepreg layer to a backing paper and then the prepreg tape is cut to a depth enough to cut the prepreg tape but not the backing paper. A unnecessary portion of the prepreg tape is removed from the backing paper to obtain a cut prepreg tape. A laminating attachment is moved in a predetermined direction while urging the prepreg tape against the surface of an operating table. The cut prepreg tape is peeled off from the backing paper and the peeled off prepreg tape is bonded to the operating table. The cut prepreg tapes are successively oriented in a predetermined direction and juxtaposed to form a laminated sheet. When the sheet is mounted on a mold of a predetermined shape. When the impregnated thermosetting resin is perfectly cured under heat and pressure a product useful for assembling various vehicles can be obtained.
