Application and Evaluation of New Design Method by Using Carbon Fiber-Reinforced Plastics

Abstract

This research is the application of new design method for integrating the optimum shape and strength design process. The products is manufactured from product design which can use the advanced characteristic of composite materials obtained by the experiment and the numerical analysis. Here, the collaboration of the design and the strength analysis by using composite materials is carried out. The products, which are made from high strength composite materials, need new product design technology which draws out the characteristic of material's advantage. Existing product developments tend to separate product design from product planning. The process consists of three stages as follows; 1) Planning the shape of the product by designers, 2) Calculating the strength by numerical analysis, 3) Designing the product. It is performed a styling design by requirements from the engineering point of view. By using this design method of high-strength materials, we designed new styling ZIGZAG Chair made of the carbon fiber reinforced plastic with excellent strength and lightweight.

Study of optimum shape and strength design of the redesigned Zig-Zag chair

“…2) by Haruhiko Iida [5][6][7]. It was made of CFRP with some folds for reinforcement, and was drastically lightened.…”

“…1) [5]. It was designed in 1934 by Gerrit Thomas Rietvelt who was a Dutch architect and cabinet manufacturer.…”

“…In this study, CFRP which is composite material and has very high specific strength and elastic modulus is targeted. We examine its material characteristic, and pursue the optimum structure design by using its material characteristic effectively [3][4][5]. Development of new product design method integrated with strength evaluation and styling enables them to be commercialized.…”
