16 Textiles in defence* Richard A Scott Defence Clothing and Textiles Agency, Science and Technology Division, Flagstaff Road, Colchester, Essex CO2 7SS, UK 16.1 Introduction To be prepared for War is one of the most effectual means of preserving Peace (George Washington, 1790)1 Defence forces on land, sea, or air throughout the world are heavily reliant on tech- nical textiles of all types – whether woven, knitted, nonwoven, coated, laminated, or other composite forms. Technical textiles offer invaluable properties for military land forces in particular, who are required to move, live, survive and fight in hostile environments. They have to carry or wear all the necessities for comfort and sur- vival and thus need the most lightweight, compact, durable, and high performance personal clothing and equipment. The life-critical requirements for protecting indi- viduals from both environmental and battlefield threats have ensured that the major nations of the world expend significant resources in developing and providing the most advanced technical textiles for military use. 16.2 Historical background Military textile science is not new, and one of the earliest documented studies can probably be credited to Count Rumford, or Benjamin Thompson. Rumford was an American army colonel and scientist who issued a paper in 1792 entitled ‘Philo- sophical Transactions’, which reported on the importance of internally trapped air in a range of textile fabrics to the thermal insulation provided by those fabrics.2 He was awarded the Copley Medal for his paper, as the significance of his discovery was recognised immediately. * Copyright MOD (1997) DCTA, Colchester, Essex CO2 7SS 426 Handbook of technical textiles 16.2.1 Pre-Twentieth century Up until the end of the 19th century military land battles were fought at close quar- ters by individual engagements. -

Appendix 1 Sources
APPENDIX 1 SOURCES UMIST: DEPARTMENT OF TEXTILES Most of the work described in this book comes from research in the Department of Textiles, UMIST, under the direction of Professor John Hearle. It started with the purchase of a scanning electron microscope with a grant from the Science Research Council in 1967, together with five-year funding for an experimental officer and a technician. Since 1972, the staff have been supported by general UMIST funds; a second grant from SERC enabled a replacement SEM to be bought in 1979; industrial sponsors, listed below, have contributed through membership of the Fibre Fracture Research Group; special research grants have been made by the Ministry of Defence (SCRDE, Colchester, and RAE, Farnborough) and jointly by the Wool Research Organization of New Zealand (WRONZ) and the Wool Foundation (IWS); and other research programmes and contract services have contributed indirectly to our knowledge. Pat Cross was the first SEM experimental officer and she was followed in 1969 by Brenda Lomas, who retired in 1990. Trevor Jones then took on responsibility for microscopy in the Department of Textiles in addition to photography. Over the years, many staff and students have contributed to the research. Their names are given below. Some have worked wholly on fibre fracture problems. Others have used fracture studies as an incidental element in their work.

Endumax® – an Ultra-Strong Thin Film with a High Modulus Contents
Endumax® – an ultra-strong thin film with a high modulus Contents What is Endumax? 3 How is Endumax produced? 4 What types of Endumax are available? 6 What can Endumax be used for? 8 Endumax – a unique combination of properties 10 About Teijin Teijin is a technology-driven global group, based in Japan, offering advanced solutions in the areas of sustainable transportation, information and electronics, safety and protection, environment and energy, and healthcare. Its main fields of operation are high-performance fibers (e.g., aramid, carbon fibers and composites), healthcare, films, resin & plastic processing, polyester fibers, product conversion and IT. The group has some 150 companies and around 17,000 employees spread over 20 countries worldwide. Endumax is part of Teijin’s high- performance fibers business, which also produces the aramid fibers Twaron, Technora and Teijinconex. Teijin’s high-performance fibers business is based in Arnhem, The Netherlands. 2 What is Endumax? Endumax film is a new, patented high-performance film developed and made by Teijin. It can be used in a wide variety of products for various market segments – anywhere, in fact, where there is a need for superior strength, safety, light weight or durability. For example, Endumax is used worldwide in applications and markets ranging from ballistic protection (armoring and bulletproof vests), ropes and cables to cargo containers, laminated sails and even loudspeakers. The film shape of Endumax allows for easy processing and seamless integration into the application of the customer. Super-strong and more Weight-for-weight, Endumax is 11 times stronger than steel. But Endumax offers more than incredible strength. -
A Perspective on High-Performance CNT Fibres for Structural Composites
A Perspective on High-performance CNT fibres for Structural Composites Anastasiia Mikhalchan, Juan José Vilatela IMDEA Materials Institute, C/Eric Kandel 2, Getafe, Madrid, Spain, 28906 This review summarizes progress on structural composites with carbon nanotube (CNT) fibres. It starts by analyzing their development towards a macroscopic ensemble of elongated and aligned crystalline domains alongside the evolution of the structure of traditional high- performance fibres. Literature on tensile properties suggests that there are two emerging grades: highly aligned fibres spun from liquid crystalline solutions, with high modulus (160 GPa/SG) and strength (1.6 GPa/SG), and spun from aerogels of ultra-long nanotubes, combining high strength and fracture energy (up to 100J/g). The fabrication of large unidirectional fabrics with similar properties as the fibres is presently a challenge, which CNT alignment remaining a key factor. A promising approach is to produce fabrics directly from aerogel filaments without having to densify and handle individual CNT fibres. Structural composites of CNT fibres have reached longitudinal properties of about 1 GPa strength and 140 GPa modulus, however, on relatively small samples. In general, there is need to demonstrate fabrication of large CNT fibre laminate composites using standard fabrication routes and to study longitudinal and transverse mechanical properties in tension and compression. Complementary areas of development are interlaminar reinforcement Corresponding Author. E-mail: [email protected] (Anastasiia Mikhalchan) Corresponding Author.
