Tokyo Rope MFG’s carbon fibre composite cable adopted in the Hampton Roads bridge tunnel expansion project

Tokyo Rope International, a group company of Tokyo Rope MFG, announces their carbon fibre composite cable (CFCC), manufactured and sold based on the company’s own research and development, has been adopted for the Hampton Roads bridge tunnel expansion project.

TRI_cfccThe project is one of the largest infrastructure projects currently planned in the United States, with a total construction cost of $3.8 billion and a 16km link between Norfolk and Hampton, Virginia. This is a project to expand the maritime aorta. The Hampton Roads bridge tunnel, which currently has two lanes on each side and is normally subject to large-scale traffic congestion during peak traffic times, will be doubled to four lanes on each side to eliminate traffic congestion and improve traffic volume.

In this expansion project, which brings together a high level of technology and knowledge in various fields such as materials engineering, design, construction, and transportation engineering, Tokyo Rope’s CFCC was selected as it is suitable for use in the harsh environment at sea. The material was adopted due to its strength, corrosion resistance, light weight, and life cycle cost. In this project, the CFCC is used as a girder and pile tensioning material and as a reinforcing bar for about 8.6km above the sea, with a total length of 5,486km.

Tokyo Rope’s CFCC and related products have already been adopted in 36 projects in nine states in the United States. The group will contribute to the construction of safe and secure infrastructure by manufacturing and supplying quality products such as CFCC in the United States and other countries around the world.

Heat wear for outdoor work in winter

Iris Ohyama adopted lightweight, quick-warming carbon nanotube heaters for a heat wear product that is easy to use and wear in daily life. The product will be released at shopping centres and internet sites nationwide.

Clothes that use heaters are popular among outdoor workers because they can warm the body easily and safely without using fire. However, they are difficult to use in daily life because they are not available in small sizes, the heater part is hard, they are bulky when worn and they make it difficult to move, so elderly people and women tend to avoid using them.

Iris Ohyama’s heat wear uses carbon nanotubes, nano-level fibres made of carbon atoms, for the heater, and because it is thin and lightweight, it is easy to use by the elderly. Due to its low bulk, it is easy to use in daily life, for instance, when commuting or going out for a short time. In addition, it has high thermal conductivity and warms up rapidly after the power is turned on. A commercially-available mobile battery can be used for power supply. Finally, everything including the connection part of the USB terminal can be washed with water, so it can be kept clean even after outdoor use. 

Iris Ohyama will continue to develop products that are closely related to the lives of consumers and strives to bring comfort in everyday life.Iris_heatwear

New fuel cell air compressor and hydrogen circulation pump

Toyota Industries recently developed an air compressor and hydrogen circulation pump for fuel cells. These products are installed in the fuel cell vehicle (FCV) and the new Mirai announced by Toyota Motor Corporation on December 9.

Climate change is the most important issue that countries around the world are tackling. The goal of realizing a carbon-free society toward 2050 has been set in Japan as well. Against this background, expectations for FCVs are rising as the “ultimate eco-car” that uses hydrogen as fuel and emits only water when driving. Furthermore, the use of hydrogen is progressing in various ways, such as the commercial use of FC systems.

Toyota_pumpThe new air compressor is a mass-produced product that improves compression efficiency by 24%, reduces weight by 35% and size by 45% compared to conventional models. In addition, the hydrogen circulation pump uses a new seal structure to change the material from conventional stainless steel to aluminium, achieving a 41% weight reduction.

In addition to products for FCVs, Toyota Industries is working to popularize FC technologies such as FC forklifts and FC towing tractors in the industrial vehicle field, which is their main business area. Going forward, they will continue to expand the line-up of FC-related products and contribute to the realization of a hydrogen-based society.
