Abstract
A method for joining unidirectional tapes is provided. The method includes placing a plurality of unidirectional tapes by abutting without overlapping an end of one of the unidirectional tapes with an end of other one of the unidirectional tapes at a butt joint. The unidirectional tapes includes a resin material and a plurality of fibers running in a running direction. The method further includes placing a prepreg including a resin material and a plurality of short fibers over the butt joint to cover an area surrounding the butt joint such that the short fibers run in the running direction. The method further includes fusing the prepreg by applying heat such that the short fibers are fused into a matrix of the unidirectional tapes at the butt joint.
