The Carbon-Fiber Business

Inorganic fibers which include structural glass, ceramics, boron, and carbon, form a smaller but growing market estimated at 1.8 billion worldwide in 1990.1 11 1 Optical glass, which is a specialized product, is not included. The inorganic fiber market is divided as shown in Table 8.1. [Pg.167]

Fiber Production (metric ton) Average Cost ( /kg) World Market ( million) [Pg.167]

G lass is still by far the dominant fiber material, especially on a tonnage basis, but it is increasingly challenged by carbon in many high-performance applications, and the production of carbon fibers has increased rapidly in the last 20 years, going from a few tons per year to the present level estimated at 5000 tons. [Pg.167]

This rapid growth is the direct result of two major factors  [Pg.167]

The remarkable properties of these fibers, properties which are continuously upgraded [Pg.167]


Nippon Graphite Fiber Corporation, Tokyo, Japan the carbon fiber business of Nippon Petrochemicals was forwarded to Nippon OU Co. in 1993 and in 1995, Nippon OU and Nippon Steel formed a joint company, Nippon Graphite Fiber Corporation, a pitch based carbon fiber business. This company make the world s smallest diameter (6 pm) pitch based carbon fiber. Produce Granoc yam the XN grades are based on petroleum pitch and YS grades are based on coal tar pitch. Produce woven fabric and supposedly have the lightest carbon fiber fabric at 60 gsm made from k pitch fiber (YT50 yarn). [Pg.1127]

Japanese Dominance and internationalization. The carbon-fiber business is dominated at the present by Japanese companies such as Toray, Toho, Mitsubishi Rayon, Sumika, and Asahi Nippon. These firms, to a great degree, control the patents, the licensing, and the manufacturing of carbon fibers produced from the basic wet-spun PAN precursor. This precursor is aiso produced by the British firm Courtauld but is not produced in the U.S.I l... [Pg.168]

The number of such examples, however, is not high. In many other examples of advanced-performance materials, such as DuPont s Kevlar and Allied Signal s SPECTRA, the volume applications associated with system-for-system substitution has not yet occurred at a level necessary to pay back the development and commercialization costs already expended. High-performance ceramics is another area in which the early promise has yet to materialize. The consequences of Eckstut s life-cycle dynamics have been overcapacity and severe rationalization in high-performance carbon fiber businesses, some specialty alloy activities, and high-performance polymer composites. Thus, with critical technologies that involve advanced-performance materials, we need to better understand how to exploit their value in a commercially viable way. [Pg.43]

Next came acquisitions, funded in part by the divestitures, that reinforced the learning base in the paths that the firm had long followed. In films and fibers it purchased Exxon s carbon fiber business in 1984, Exxon s film composites activities in 1985, and Hercules s olefin fiber carpets in 1989. Later, in 1992, it traded its acrylic assets to ICI for the latter s nylon business, plus 41 million. In paints and finishes Du Pont obtained Ford s North American automotive paint division in 1986, followed by a joint venture with ICI to expand the same market in Europe, and one with Kami Paint to do so in Japan and East Asia. In agricultural chemicals it acquired Shell s agricultural chemicals division in 1986, and later in 1992 collaborated with Shell to develop specialized insecticides. For Du Pont, sustaining its technical and functional capabilities in long-established paths in which it was a competitive leader remained a basic strategy. ... [Pg.51]

USA by Raytheon, following the success of its all composite turboprop, Starship. Called Premier 1, the business jet has an all RP fuselage with metal alloy wing. The carbon fiber/epoxy honeycomb fuselage is produced by computer-controlled automated machines, which are quicker than the hand lay-up used for the Starship. The cabin is reported to be 178 mm higher and 203 mm wider than competitors. The construction saves weight and is stronger than alnminnm. [Pg.581]

The first model is based on the carbon fiber experience. Once the high-performance aerospace business had been established, other markets, such as racing cars, sporting goods, and industrial products, were developed. All of these applications have grown in volume as prices have come down. The second model is based on the Kevlar fiber experience, in which DuPont was skilled in polymer fiber technology prior to the development of Kevlar. [Pg.98]

In 1984, DuPont acquired the Exxon pitch based carbon fiber business and it was highly probable that the DuPont fibers were based on the Exxon patents [58] using a neophase pitch, which had been extracted with solvent, as precursor material. Initial studies revealed an oriented core microstructure [59]. Later work showed E130 to have an oriented core [60], or radial [61], but all workers agreed that there were many disclinations, which is consistent with the low graphitizability of the fiber. Kogure, Sines and Lavin [61] are insistent that... [Pg.305]

Toray Ind. is the largest manufacturer of synthetic fibers, engineering piastics, poiyester fiim and carbon fiber in Japan. The company was estabiished in 1926 as a manufacturer of viscose rayon. The year 1950s was a period of high growth as it moved into the production of synthetic fibers, such as nyion, poiyester and acrylics. From the 60s through the 80s, Toray enjoyed further expansion as it diversified its businesses. In 1971, it... [Pg.10]

Table 1 shows some examples of our basic research and new businesses. Toray commercialized nylon 6 fiber In 1950. The raw material, -caploractam, was produced by a conventional multi step proress at that time, but it has been today completely replaced by my invention. The business of carbon fiber and advanced composite materials was the outcome of basic research on oi anic synthesis using phosphorous compounds in our Basic Research Laboratories. Investigation in holography provided a researcher with the idea to use a holograph as a memoi, and the world-first Kanji-Printer was introduced in 1974, even though the memory was later replaced by a semiconductor. Our pharmaceutical business was initiated from basic research on interferon and biotechnologies. In 1985 we... [Pg.11]

Sales of these new businesses are also shown in this Table. The sales of caploractam has, today, reached 350 million dollars. The sale of carbon fiber and advanced composite materials is 200 million dollars. The sales of medicine has grown to 150 million dollars. [Pg.11]

DuPont makes the zigzag radial structure to accommodate residual stresses. So the micrometric zigzags of El 30 favor tensile strength but the nano texture is unfavorable to graphitization. Conoco Inc. took over the business from DuPont and were to initially build a random oriented carbon fiber mat plant based on a mesophase petroleum pitch, but the... [Pg.307]

At the time, Amoco Chemicals Company was a wholly owned subsidiary of Standard Oil Company (Indiana), which later changed its name to Amoco. Amoco Performance Products, Inc., was created with the purchase of Union Carbide s high-performance polymer and carbon fiber groups in 1985. BP inherited the polymers business in its merger with Amoco and then divested it to Solvay, where Torlon and the other high-performance polymers are now within the Solvay Advanced Polymers, LLC, business unit. [Pg.258]
