In many technical applications, fibre-reinforced composites with textile high-performance fibres made of carbon or glass are being used. The fibres qualify for their high strength and stiffness due to their physical and chemical characteristics. It is necessary to guarantee a high safety level under all possible loading constellations. Besides the usual service loads, the topic of extreme loads that work along with high forces and high impact velocity is of increasing importance. For these so-called impact loads, the processes within the structural components have to be analysed and material models suitable for prognoses should be derived from them. The existence of suitable test machines and test methods is a prerequisite for that, yet for filament yarns they are not state of the art. Hence, tensile tests with high strain rates on filament yarns are performed on standard high-speed tensile testing machines. This leads to problems when analysing and interpreting the results and therefore, it is necessary to develop special testing machines for filament yarns.

Some studies suggest that the number of patent applications can be used as an indicator to quantify the potential for innovation of industry sectors such as the textile industry. This paper shows the distribution of worldwide economic power and patent applications between 1978 and 2004 in the textile and textile machinery industry based on the example of for Germany. The number of patent applications from the textile sector is compared to that of other industries. Subsequently, the patent statistics are broken down into individual enterprises with outstanding numbers of applications, as well as to individual countries and branches within the textile industry.

This paper presents the research activities in the field of textile reinforced concrete carried out by the Institute of Textile and Clothing Technology (ITB) of the Technische Universität Dresden, Germany. Extensive research has been conducted with the aim to fully use the tensile strength of the applied high-performance fiber material in the reinforcing textile. To achieve this, the textile machinery was adjusted and improved and new testing methods were developed. This research has resulted thus far in several innovative applications for the repair of existing buildings as well as the production of precast concrete parts.
