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. -

Hybrid Self-Reinforced Composite Materials Based on Ultra-High Molecular Weight Polyethylene

The hybrid materials consist of two parts: an isotropic UHMWPE layer and unidirectional SRC based on UHMWPE fibers. Hot compaction as an approach to obtaining composites allowed melting only the surface of each UHMWPE fiber. Thus, after cooling, the molten UHMWPE formed an SRC matrix and bound an isotropic UHMWPE layer and the SRC. The single-lap shear test, flexural test, and differential scanning calorimetry (DSC) analysis were carried out to determine the influence of hot compaction parameters on the properties of the SRC and the adhesion between the layers. The shear strength increased with increasing hot compaction temperature while the preserved fibers’ volume decreased, which was proved by the DSC analysis and a reduction in the flexural modulus of the SRC. The increase in hot compaction pressure resulted in a decrease in shear strength caused by lower remelting of the fibers’ surface. It was shown that the hot compaction approach allows combining UHMWPE products with different molecular, supramolecular, and structural features. -

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.
