Teijin said it has developed two new Twaron and Technora para-aramid fibre fabrics to protect facilities such as lodges and evacuation shelters from airborne volcanic fragments measuring about 10 cms.

“The new fabrics are designed and produced in accordance with the Japanese government's new regulations for strengthening evacuation facilities located near volcanos,” a Teijin press release said.

“The Ministry of the Environment is now using the fabrics to refurbish the roof of the Ebino Eco Museum Center in Kirishima-Kinkowan National Park on the island of Kyushu in southern Japan,” Teijin added.

Teijin developed its new Twaron and Technora para-aramid-fibre fabrics in consultation with the Cabinet Office, the National Defense Academy and the Mount Fuji Research Institute.

According to Teijin, in simulation tests, the fabrics demonstrated their capacity to withstand fist-sized airborne fragments similar to those produced during the September 2014 eruption of Mt. Ontake.

Teijin further added that it is the world's only company manufacturing two types of lightweight, strong and heat-resistant para-aramid fibres.

“Twaron offers six times more tensile strength than steel of the same weight, as well as superior heat resistance and elastic modulus,” the company informed.

“While, Technora boasts even greater tensile strength and resistance to impact, fatigue and chemicals,” Teijin observed.

Teijin will focus marketing activities on local municipalities and private enterprises in areas prone to volcanic activity, with sales expected to reach 50,000 square metres by fiscal ending March 2017.

Protecting evacuation facilities and other structures from large airborne fragments is an important issue in Japan, one of the world's more active volcanic regions.

While materials such as reinforced concrete and steel offer required levels of strength and durability, transporting heavy materials and large equipment to highlands can lengthen the construction period.

High-performance composite materials that offer new value are one of the four business pillars in the transformation and growth strategies of Teijin's current medium-term business plan.

Promising fields for Teijin's high-performance fibres include safety, infrastructure and energy, functional paper and filters, and mobility.

The company is putting a high priority on leveraging its high-performance materials in advanced solutions to meet diverse demands in the global market.

Renowned for their strength, sustainability, safety, heat resistance and low weight, Twaron, Technora, Teijinconex and Teijinconex neo are used worldwide for various applications.

These include automobiles, ballistic protection, marine products, civil engineering, protective clothing, and oil drilling. (AR)
