Abstract: Continuous fibres from alkali resistant glass can be used as reinforcement of concrete elements. In cross section the fibres consist of several hundred or thousand single fila-ments. The bond properties between these filaments have an important influence on the loadbearing behaviour of the composite material. Based on the failure of outer filaments from a fibre bundle according to the model presented by Ohno & Hannant it is shown by means of test results that the strength in the composite material depends on the fibre volume content. The hypothesis is established that this is due to the fact that glass strength depends on the size of the stressed surface. Furthermore it is proven that it is not possible to conclude composite strength from filament strength. Generally, it seems that testing a roving by applying the load with friction forces might be suitable for estimating the strength of the composite material.
