This study is the application of new design method for integrating the product design (styling and functional design) and the engineering design (strength design of structure), which can make the best use of the composite materials' characteristics obtained by the experiment and the analysis. Among them, the carbon fiber reinforced composite plastics (CFRP) have excellent high strength and lightness. Here, using these materials' characteristics, ZIGZAG Chair made from wood, which had the refined style, was redesigned by CFRP. In this redesign process, the engineering point of view was used as a new proposed design method. The designed ZIGZAG Chair was manufactured by hand lay-up molding of CFRP according to analytical results, and its styling and strength were evaluated. The analytical results, that is, strength and displacement, were in good agreement with the pilot model's one.

“…In addition to the hybridization of fibers, analysis of loading conditions is crucial to design strong structures without any waste of material. Iida et al (2014) have designed a zig-zag chair made of carbon-fiber-reinforced polymer. calculate the loading conditions and fold the carbon fiber reinforced polymer fabric for optimized chair design.…”

The structural properties of Fiber Reinforced Polymers (FRP) encourage designers and architects to use textiles as a load-bearing architectural material to create lightweight and strong structures. Manufacturing techniques of FRPs are mostly concentrated on the molding method. This method requires an extra mold fabrication that causes waste of material. This study focuses on integrative weaving and 3D printing fabrication methods, which emphasize the lightweight property of the material. This integrative method avoids excessive material waste during fabrication by using an additive approach. 3D printing on textiles prevents significant deformation in a specific direction of the fabric instead of using any kind of synthetic resin for stiffening the fabric. Additionally, structural behavior simulation allows designers to understand the different loading conditions and maximize the strengths of each textile design by adding more material where it is needed for possible architectural applications.

“…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.…”

Existing product developments tend to separate the product design from the product planning. After the planning of shape and style of the product by designer, its strength is evaluated by engineering analysis, and then the product will be finally designed.This research, aims at the construction of the optimum shape and strength with the sophisticated design of the machine and structure members. The composite material that are typified by carbon fiber reinforced plastic (CFRP) has very high specific strength and it is light compared with metals. So, it is possible to produce the complex and lightweight products by using these composite materials.Here, the material characteristics were expressed as a combination of some simple element models of this high strength carbon fiber reinforced materials CFRP. By the simulation design technique which used the FEM analysis was proposed. To get the elastic modulus of CFRP which is influenced by fiber direction, three-point bending test was performed. In this experiment, two types of specimens which have different fiber direction each other were tested.As a design target, the redesign of Zig-Zag chair was selected, which was designed by Gerrit Thomas Rietveld, who was a Dutch architect and furniture designer. The optimum design items are the good shape, best strength and weight lightening.
