Abstract: The principals of the bond behaviour of textile reinforcements in concrete are discussed. It is shown that a yarn consists of filaments which are either outer or sleeve filaments which are connected to the concrete or inner filaments or core filaments which have no direct conctact to the concrete matrix. According to the situation the sleeve filaments are much better connected to the concrete whereas the core filaments can more or less slip with low friction. As soon as a yarn is impregnated with a resin all filaments were thorough tightly together. Various models have been published in order to simulate this situation. These models are presented and discussed. Further, testing of bond has been realised by various methods. There is a one-sided pullout test and there is also the two-sided embedment test. Both tests lead to realistic results which can be put into analytical models. These models has been converted to such models that they are applicable in numerical simulations. Validations by the use of non-linear finite element programmes are shown. Finally, the pullout behaviour of the fabric is shown. The pullout of a fabric is modelled in a schematic which takes into account the properties of the matrix and the property of the bonded and de-bonded fabric.
