1 Technology Roadmap Nanotechnology Applications in Manufacture of Carbon Fibers and Carbon Fiber The Roadmap for Nanotechnology Applications in Manufacture of Carbon Fibers and Carbon Fiber (hereafter Roadmap) is a review document describing the multi-layer system of strategic development for carbon fiber industry within a common timescale. It also contains the parameters that reflect economic efficiency of advanced technologies and products characterized by a high potential demand and attractive consumer properties. The Roadmap is based on the expert evidence as well as on the review of Russian and foreign analytics. The Roadmap refers to the demand structure for carbon fibers and outlines the most prospective markets for carbon fiber products. The Roadmap provides an assessment of technical capabilities required for manufacturing of carbon fibers with the most preferable consumer properties which would allow generating the significant competitive advantages for goods produced involving carbon fibers. Subject Overview Carbon fiber (CF) is a nanostructured organic material containing % of carbon, characterized by high tensile strength and elasticity modulus. Nowadays carbon fibers are used primarily as reinforcing fillers in composite materials. Simultaneously they are considered as the most potentially advanced structural materials used into domestic products and their elements. The Roadmap covers the following four basic types of carbon fibers whose properties are expected to obtain widespread long-term applications for its major consumer markets: 1. Polyacrylonitrile (PAN)-based carbon fiber; 2. Rayon-based carbon fiber; 3. Pitch-based carbon fiber; 4. Vapour-grown carbon fiber. Competitive advantages of each type that listed above are shown in Table 1 below. State Corporation Russian Corporation of Nanotechnologies, 2010

Rayon-based carbon fibers are reasonably considered to be used prospectively in medical applications as well as in the areas where the use of this particular carbon fibers type is required by respective norms and regulations. The employment of pitch-based carbon fibers is restricted to special applications. In particular, it is estimated that a combination of pitch- and PAN-based carbon fibers could be integrated within the production of gas centrifuges. Regarding vapour-grown carbon fibers, it should be mentioned that their production technology is at its early, research stage now, so it is a subject to significant enhancements, therefore products, employed this type of carbon fibers were not introduced into the market yet. However, evidences from market trends research confirms that vapour-grown carbon fibers are anticipated to have a wide range of applications which could be accounted for their low future price at relatively high performance characteristics. Carbon fiber composite materials are complex materials formed by combination of carbon fibers, as reinforcing elements, and a binding substance (matrix). Mechanical and other properties of a carbon fiber composite material could be defined by three factors: tensile strength of carbon fibers, rigidity of the matrix and fiber-matrix adhesion. Carbon fiber composites excel in all three key parameters of any structure or construction: strength, rigidity, and low specific weight. Carbon fibers predominate over all known reinforcing fiber types involved in composite materials production in terms of tensile 1 The " " mark indicates that the parameter is available. Parameters' degrees are marked as follows: " " high; " " medium; " " low. The " " mark shows that the parameter is not available or does not exist. 2 Vapour-grown carbon fibers are not currently present on the market. New market niche launch is anticipated in the future.

3 strength and tensile modulus. That results in enhanced tensile strength and tensile modulus properties of carbon fiber composites that exceed those one, that aluminum and steel are characterized. Moreover, carbon fibers' specific weight does not outreach 2 g/cm 3 which allows generating structures or constructions twice as light as those that made from aluminum and five times as light as those that made from steel. The Roadmap covers the following four core types of carbon fiber composites whose properties are expected to obtain all the anticipated indicators that would facilitate their long-term broad practical insight: 1. Carbon fiber polymer-matrix composites (carbon fiber-reinforced plastics); 2. Carbon-carbon composites; 3. Carbon fiber metal-matrix composites; 4. Carbon fiber ceramic-matrix composites. A comparison of all above-listed characteristics of four carbon fiber composites types are shown in Table 2 below.

It is estimated that carboncarbon composites would take the niche of special applications, in particular in the areas with sufficient technological background (e.g., brakes, etc.). Metal matrix composites would find their place mostly in the aircraft industry while ceramic matrix composites would find an industrial application under high-temperature conditions.

4 World Market of Carbon Fibers According to the market research findings, the world market of carbon fibers is expected to progress following one of the three prospective scenarios (see Figure 1 below): Figure 1. World Market of Carbon Fibers( MM $) Pessimistic Moderate Optimistic The optimistic scenario assumes that the global economic crisis would slow the CF annual market growth down to 10% (or even it would allow maintaining the current annual growth rate of 15%). Then along with the begging of the world economy growth resumption the CF market real growth rates would also subject to recovery. They are expected to regain its present level and would set up down the ceiling of 20-25% per year. However, due to the reduction in prices the market growth in monetary terms would be lower, comprising 10-15% per year. The major anticipated market drivers should comprise from the following three components: 1) growth in demand for CF encouraged, among others, by introduction of respective regulatory requirements and standards; 2) technological advance; 3) reduction in CF price. The moderate scenario involves that after reaching the bottom of 5% of annual growth rate over , the market growth rate would recover. On average, the market annual growth rate in in real terms would equal to 10-15% in the monetary terms, while because of the price downturn, the market would grow by 5-10% annually. The major market drivers that could foster the growth under this scenario would be the government support given to strategic industries, development of innovative applications, and gradual growth in demand for CF products associated with the requirements of defense industry. The pessimistic scenario is based on the assumption that the problems in the world economy would primarily and most gravely affect the knowledge-intensive industries. In this case, in the nearest two years the anticipated annual market growth rate would stagnate at 2-3% and the annual growth would have rather an "inflationary" character State Corporation Russian Corporation of Nanotechnologies,

5 floating at 5-6% later on. Yet, experts evaluate the probability to implement this pessimistic scenario as rather low. Russian Market of Carbon Fibers The investigation of the Russian market of carbon fibers revealed the following development in three following scenarios (see Figure 2 below): Figure 2. Russian Market of Carbon Fibers (MM $) Pessimistic Moderate Optimistic The optimistic scenario incorporates that the structure of carbon fiber consumption in Russia would generally follow the international pattern while the production would reach a new quality, quantity and price level. According to this scenario, by 2013 the market growth rate would equal 45-50% per annum in average. Furthermore in such a case the growth would result most likely into one decisive jump, rather than in gradual upward flow over the whole period. After 2017, this peak would flatten to approximate to the reflection of the world average growth rate of 10-20%. In the medium term Russia may be exporting up to 20% share in its total domestic CF production. By 2020, Russia's share in the world CF production volume is expected to reach the 5% level. The moderate scenario is based on the assumption that by 2020 Russia would produce about 3% of the world's CF yield while exporting up to 5-10% of its domestic output. The civil, non-defense needs would be met by the emerging production of mediumquality fibers along with maintaining the country's positions in production of highmodulus fiber at a present level. By 2013, carbon fibers output is expected to reach 600 tons per annum which corresponds to an average annual growth rate of 30-35%. However, a gentle growth in this case actually regards to be unlikely: it is anticipated that in 2013 (the year when the Russian federal program for small-scale chemical plants will be completed) the fiber production output would jump up sharply. At the same time in this growth rate could get even faster, thereafter slowing down to the 10-15% annual limits. State Corporation Russian Corporation of Nanotechnologies,

6 The pessimistic scenario assumes that Russia would not have sufficient resources to ensure a considerable increase in CF production output and to boost its quality up to the competitive level. That would be the reason for an estimation of the country's market share in the world CF production on the 0.5% line without any prospects to rise up. In this case the country's CF export outlook in terms of product quality and its price would remain uncertain. Simultaneously, the growth in domestic CF consumption would be most likely covered by import supplies.

10 CF-based composite materials are directed to find use in a wide range of a certain industrial applications in aircrafts and other equipment where moment of inertia performs as a key factor (fly wheels and high-speed gas centrifuges, for instance). CF-based composites are also material of choice for deep-water drilling for a shelf exploration and for a presence in strategic offshore regions, for instance, on the Arctic shelf. Following the results of carried investigations it is also advisable that industrial applications of carbon fiber should be expanded to include the manufacture of high-performance specifications equipment and likewise vehicles. That could be afforded and achieved, in particular, in the automotive industry to reach significant automobile weight savings and in the ship-building industry to provide ships with low-weight and durable skin. According to the research findings, CF-based materials can also be successfully applied in the manufacture of medical-care products and equipment (wheel chairs, medical implants, medical drapes) as well as products for sports and leisure. These applications are shown as separate, self-sufficient areas on the Roadmap. State Corporation Russian Corporation of Nanotechnologies,
