“…Carbon fiber, which is the same fibrous carbon and for which an industrial manufacturing method was invented by a Japanese, grew into an industry in which the Japanese company dominates about 70 % of the world share. [22] Currently, it is used as structural material of aircrafts and strengthening material for buildings. Now the price of general-purpose products has decreased to the level of several thousand yen per kg, but it was about 100,000 yen/kg at the beginning of its commercialization.…”

Energy storage devices now require rapid charge/discharge performance, not only high storage capacity for convenient and energy efficient devices. Research and development of rapid charge/discharge storage devices are carried out in an interdisciplinary field of nanotechnology and device manufacturing, where the scope of research is very different in size and scale. This R&D is an interesting subject from the viewpoint of synthesiology, because the keys to device manufacturing are selection and combination of element technologies. In this paper, approaches and methods employed in the R&D of high performance capacitors are introduced from the discovery of innovative materials to device manufacturing, by citing examples carried out in research projects under industry-academia-government collaboration.

“…The manufacturing method that employed the concept of "minimal manufacturing" with low cost, low environmental load, high function, and low resource consumption was synthesized. The R&D for PAN carbon fiber by Nakamura et al [34] is also a combination of the breakthrough type and strategic selection type.…”

We analyzed the methods of synthetic research scenarios in each research field, and attempted extracting the common methodology. Chapter 2 addresses the basic types of synthesis of the elemental technology, chapter 3 is the analysis of the synthesis method for each field, and chapter 4 presents the characteristics of the field based on the analyzed synthesis method. In chapter 5, we present the "technological synthesis" of which the necessity in the synthesis method has been clarified, and the characteristics of the "synthesis for social introduction." By the method of analyzing the written papers, this paper attempts to synthesize the new "study" called synthesiology to connect the research results to society. 2 Basic types of synthesis of the elemental technology Kobayashi, one of the authors, proposed the examples of the basic types of synthesis of the elemental technology: (1) aufheben type (method by which a new concept is created by

“…In the early 1960s, PAN-based carbon fibers were developed by Akio Shindo. 2 To manufacture PAN-based carbon fibers, PAN is processed to a fibrous shape by spinning, and then oxidation, carbonization, and surface treatment are performed. Pitch-based carbon fibers were developed in 1970 by Leonard Singer.…”

Application of carbon fibers to biomaterials: A new era of nano-level control of carbon fibers after 30-years of development

Carbon fibers are state-of-the-art materials with properties that include being light weight, high strength, and chemically stable, and are applied in various fields including aeronautical science and space science. Investigation of applications of carbon fibers to biomaterials was started 30 or more years ago, and various products have been developed. Because the latest technological progress has realized nano-level control of carbon fibers, applications to biomaterials have also progressed to the age of nano-size. Carbon fibers with diameters in the nano-scale (carbon nanofibers) dramatically improve the functions of conventional biomaterials and make the development of new composite materials possible. Carbon nanofibers also open possibilities for new applications in regenerative medicine and cancer treatment. The first three-dimensional constructions with carbon nanofibers have been realized, and it has been found that the materials could be used as excellent scaffolding for bone tissue regeneration. In this critical review, we summarize the history of carbon fiber application to the biomaterials and describe future perspectives in the new age of nano-level control of carbon fibers (122 references).
