ABSTRACT

The properties, the amount and the arrangement of the used fibre materials have a great influence to the characteristics of the composite. Requirements on the fibres are: high fibre tenacity, a modulus of elasticity much higher than that of the mortar matrix, small relaxation under permanent load, a good and constant adhesion between reinforcement and mortar, low cost and the possibility of processing them easily on textile machinery. Alkali-resistant man-made glass fibres (AR-glass), carbon and aramid essentially meet these requirements for the design and fabrication of textile reinforcements.
