Toray becomes joint winner in Japan’s Sixth Infrastructure Maintenance Awards

Toray Industries, Inc., announced today that it was one of three joint recipients of the Minister of Economy, Trade and Industry Award in the Electricity category of the Sixth Infrastructure Maintenance Awards. This is in recognition of the development of a carbon fiber-reinforced plastics (CFRP) technique employing in-situ vacuum-assisted resin transfer molding (VaRTM) technology. Toray, Tokyo Electric Power Grid, Inc., and Yasuda Seisakusho Co., Ltd. deployed that technique to repair steel pipe corrosion on transmission towers.

This technology eliminates the need for special jigs and methods in replacement work by reinforcing pitted and corroded pipes. It can thus reduce lead times for strength assessments and cut construction costs. Another key factor in receiving this award was the broad social benefits that could accrue from applying this technology to steel-framed buildings and other structures.

The Infrastructure Maintenance Awards recognize outstanding initiatives and technology developments related to social infrastructure maintenance in Japan at facilities under the jurisdiction of a range of government bodies. These are the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Internal Affairs and Communications, the Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Health, Labor and Welfare, the Ministry of Agriculture, Forestry and Fisheries, the Ministry of Economy, Trade and Industry, and the Ministry of Defense. Experts from a range of fields screen candidates for the Minister of Economy, Trade and Industry Award, the Special Award, and the Award for Excellence.

The awards debuted in 2016 to foster Japan’s maintenance sector and recognize best practices among businesses, organizations, researchers in that field.

Award details are as follows.

1. Minister of Economy, Trade and Industry Award

For the development of a CFRP technique employing in-situ VaRTM technology to repair steel pipe corrosion on transmission towers

2. Joint recipients

Tokyo Electric Power Grid, Yasuda Seisakusho, and Toray

3. Award-winning technology

This patented in situ VaRTM technology entails placing CF sheet “TORAYCA® CF fabric” on a steel structure requiring repair, applying a film over the sheets, using a pump to create a vacuum, and injecting and curing epoxy resin. Over time, internal corrosion causes pitting and wall thinning on the steep piping of transmission towers. The conventional repair process is very labor-intensive and expensive, as it entails replacing these pipes. The three companies jointly developed a CFRP repair technique that applies in-situ VaRTM technology to corroded steel pipes that normally need replacing. This setup eliminates the need for special jigs and methods in replacement work, and can reduce lead times for strength assessments and cut construction costs.

4. Progress and potential

Applications to date for in situ VaRTM to repair steel infrastructure have included transmission towers in Japan and floating production storage and offloading facilities overseas. Work is under way extend applications to repair and reinforce steel bridges, steel-framed buildings, and other structures. Toray will keep striving to create technologies and build a value chain in which TORAYCA cloth can significantly extend the service lives and resiliency of domestic and overseas infrastructure.

Toray develops recycling technology that retains carbon fiber strength and surface quality

Toray Industries, Inc., announced today that it has developed a recycling technology that can decompose diverse carbon fiber reinforced plastics (CFRP) made from thermosetting resins while retaining the strength and surface quality of those fibers. The company drew on this technology to create a nonwoven fabric employing recycled carbon fibers.

HEAD launches more sustainable(1) BOOM RAW racquet on Earth Day by using Toray’s bio-circular carbon fibers

HEAD continues to innovate with the launch of the BOOM RAW tennis racquet, an encouraging development in the search for a more sustainable future for racquet sports. All of the carbon fibers are bio-circular carbon fibers in the limited-edition and highly innovative BOOM RAW racquet, which offers the same explosive power - along with the same fun, feel and easy playability - as the regular, in-line BOOM racquet. The bio-circular carbon fibers are manufactured by Toray and its subsidiary Toray Carbon Fibers Europe.

Toray develops durable reverse osmosis membrane

Toray Industries, Inc., announced today that it has developed a highly durable reverse osmosis (RO) membrane (see glossary note 1). This innovative offering guarantees the long-term provision of high-quality water. It also maintains the superior removal performance of Toray’s existing membranes vital for reusing industrial wastewater and treating sewage.

JEC World 2026 returns with an unprecedented content program

Recognized worldwide as the leading trade exhibition for composite materials and their applications, JEC World returns on March 10-12, 2026, at Paris Nord Villepinte as the most ambitious edition to date, in line with its motto “Pushing the limits”. As the must-attend event for the composites industry, JEC World will offer an unprecedented program, blending conferences, markets insights, technical sessions, awards, and above all, a unique experience and invaluable connections.

KARL MAYER at JEC: Multiaxial reinforced CFRP pultrusion profiles are picking up speed in the mobility sector

KARL MAYER Technical Textiles will be showcasing exciting new application potentials for multiaxial non-crimp fabrics in combination with the pultrusion process at the upcoming JEC in Hall 5, Booth C 46. The advancement of the tried-and-tested pultrusion process enables the cost-efficient production of complex CFRP multi-chamber profiles, which are used in the CETROVO high-speed metro. The world's first carbon-intensive lightweight rail vehicle of this type is designed for speeds of up to 140 km/h.

Engineering depth and diversity for composites

Airbond is the latest member of the British Textile Machinery Association (BTMA) to receive recognition for contributions to the composites industry. The engineering firm based in Pontypool, South Wales, has just received the Make UK Energy and Sustainability Award for its Lattice 3D Printing project.

Beyond the wardrobe – innovative cotton takes the spotlight

Cotton can do more – a lot more. Cutting-edge textiles and high-tech products made from 100% cotton prove just how powerfully performance and sustainability can come together. That very surge of innovation is front and centre at the 38th Bremen Cotton Conference, taking place March 25–27, 2026, at Bremen’s Parliament on the historic market square – culminating in a bold and dedicated closing session on Friday. In the spotlight: performance upgrades for pure cotton, smart strategies for circular textile waste solutions, and pioneering concepts for demanding technical applications. From natural fibre–reinforced composites to highly effective flame-retardant solutions, cotton steps out of the closet and shows the future potential woven into every fibre.

Keeping print inclusive: Empowering women in the print industry

Across all industries, cultivating a diverse and inclusive workplace is increasingly recognised as valuable and essential to long-term success. However, despite the print industry’s significant advancements in technology and innovation, visible representation of women remains limited. As the sector grapples with low recruitment, it’s important to challenge outdated perceptions. Creating real change, however, requires collective effort - no single company can do it alone.
