Plain stitch-bonded multi-plies for textile reinforced concrete

Hausding J., Engler T., Franzke G., Köckritz U., Cherif C.

Autex Research Journal

2006

Vol. 6, no. 2

81--90

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.

Fuzzy-stochastic evaluation of uncertainties in material parameters of textiles

Abdkader A., Graf W., Möller B., Offermann P., Sickert J. U.

Open textile structures made of AR glass filament yarns are finding increasing application in civil engineering, e.g. as reinforcement in thin concrete strengthening layers. A knowledge of material parameters is a precondition for the application of such materials. In this paper, experimental and numerical investigations aimed at collecting information on the uncertain material parameters of AR glass filament yarns are presented. This information serves as a basis for mathematical modelling. Uncertainty is here interpreted as fuzzy randomness, and quantified using fuzzy probability distribution functions.
