description In the study, a novel design and fabrication method which is simple, optimized press molding for CFRP on the basis of CAD data is proposed. CFRP has been widespread use for the purpose of weight reduction of transportation equipment in recent years. However, in order to expand range of purpose, reduction of production is required. To satisfy these requirements, the authors focused on press molding technique. Provided that, partial excessive or breakage of the fiber occurred due to drawled fiber by deforming force. As a solution for these problems, the authors proposed the design and fabrication method for CFRP preform which has unfolded diagram shape of objective three-dimensional model using a tow prepreg. As the result, the calculation method for generation of unfolded diagram was proposed. And the validity of unfolded diagram was confirmed by reproducing the diagram to three-dimensional shape.
