DEVELOPING FIBROUS MULTIFUNCTIONAL STRUCTURES FOR TECHNICAL APPLICATIONS

Abstract This paper describes a quick prototyping unit for fibrous multifunctional structures which has been set-up at the University of Minho. This unit provides for fast development of technical samples for a variety of special applications, mainly in the areas of health and well-being, sports goods, personnel protection, techno-fashion, the civil construction and building industries, composite materials, and so on. The unit works systematically through the areas of conceptualisation, design and simulation, development, manufacturing and testing of technical and intelligent textile materials and structures, providing solutions for technical problems. New structures are developed for specific applications where special requirements are needed. It provides the best solution in terms of materials, structures, technologies and cost. The technologies involved include advanced CAD systems, FEA (finite element analyses), testing of mechanical properties, permeability, conductivity, microscopy, as well as smallscale- computer controlled manufacturing of yarns, nonwovens, wovens, warp & weft knits, braids and hybrid structures. Special finishings and surface treatments, coating and lamination are also possible. The unit is used for research, education and to provide services for companies in emerging markets for advanced textile materials. Examples of the novel products developed are provided.
