The application of high temperature resistant resins in the field of composites has its own characteristics and advantages, and the industry is further expanding its applicability to composite materials. The major high temperature resistant resins are bismaleimide resins, polyimide (PI), cyanate ester resins, high temperature resistant epoxy resins, phenolic resins, and high temperature thermoplastic resins polyether ether ketone (PEEK), polyphenylene sulfide (PPS), polyphenylsulfone (PPSU), polyethersulfone (PES), and polyetherimide (PEI).The high temperature composite resins market surpassed USD 110 million in 2018, and is expected to continue to grow and will account for more than USD 1 billion annually by 2025.
1.Aerospace
High temperature resins used in military and commercial aircraft engines have a long history in the composites industry. The aerospace and defense industry holds the largest share of the global high temperature composite resin market. In the complex and high-performance aerospace field, carbon fiber / epoxy resin composites can meet a variety of functional requirements in the long-term use of up to 130 ° C temperature, and can withstand short-term peaks of up to 204 ° C to meet the cold end of the high-performance engine components of the temperature, quality, strength, modulus of the requirements, in the fan magazine and containment ring, fan blades, fan hood, nacelles and thrust reverser device and other components. It has a wide range of applications. The (long-term) operating temperature range of bimatrix resin materials is wide, generally from 130℃ to 260℃. They are widely used for load-bearing structures and heat-resistant structures in aviation and aerospace vehicles and engines.
2. Other market applications
Although most of the demand is in the aerospace sector, transportation is one of the industries that have seen increased acceptance, mainly in under-the-hood applications. Due to stringent regulations regarding fuel economy and reduction of carbon emissions, the automotive industry has placed high emphasis on weight reduction by replacing metal parts with lightweight composite parts. Fuel efficiency standards have led to a reduction in engine size, creating a demand for lighter, more compact components. Very tight spaces have brought many components under the hood closer to the engine. New powertrain assemblies and components in under-the-hood applications are often required to operate continuously at temperatures above 200 °C. The engine is often used in a wide variety of applications, such as Formula One (F1). Racing cars such as Formula 1, for example, also require high-temperature resins in a variety of applications, as do heat shields, which to some extent also generate demand for high-temperature composite resins. Other applications include electrical, electronics, and oil and gas. Switch gear, circuit breakers, connectors and housings are key composite applications in the electrical/electronic industry where high temperature resins may be used.
3. High market concentration in North America and Europe
North America, home to major OEMs such as Lockheed Martin, Cessna, Gulfsteam, Boeing, and others, has the largest demand for high temperature composite resins globally, with the U.S. accounting for more than 90% of the region's share.Lockheed Martin opened a new manufacturing facility in Florida, U.S.A., to ramp up F-35 aircraft production rates. The second largest region in Europe is also home to major OEMs, including Dassault Aviation, BAE Systems, and Airbus Group, driving demand for high-temperature composite resins. Germany, France, and the U.K. are the top three countries, accounting for nearly four-fifths of European demand, and the Asia-Pacific region will see robust demand over the next few years, with some major developments primarily in regions such as China and India. In response to the F-35 fifth-generation fighter, China has also unveiled the Chengdu J-20 fifth-generation fighter, confirming the demand for high-temperature composites. India is also likely to see impressive growth, with various OEMs investing in the country to establish manufacturing bases for their aircraft programs.
4. Low competitive market
This market is characterized by a high degree of market concentration, with the top three companies, Solvay S.A., Koninklijke TenCatenv and Hexcel, having a market share of more than 60%. The market consists of a small number of companies specializing in selective high temperature resin systems. North America is the manufacturing center for high temperature composite resins, with major resin manufacturers, OEM players in the end-use industry along with composite parts manufacturers. Of the big three, Solvay S.A. and Koninklijke TenCate B.V, both of which are based only in North America, have their main concentrations in selective high-temperature resin systems; for example, the Lonza Group has launched a new range of cyanate ester resins, Primasetce-320 For example, Lonza Group has launched a new series of cyanate ester resins - Primasetce-320 - to meet the automotive market's demand for short-cycle processes, while Huntsman offers a system of epoxy phenolic resin resins with better heat and chemical resistance than unmodified solid epoxy resins.
5. Wide range of future applications
In targeted applications, high-temperature resins are competing with metals such as nickel, titanium, and their alloys. The high cost of high-temperature resins is one of the major bottlenecks in large-scale applications. However, with the continuing trend toward engine downsizing and lightweighting, they will find new growth prospects in high-performance applications in high-end industries. Enhanced innovation to reduce resin costs and increase resin utilization through the AFP/ATL process will be the key to increasing market share in the future.
