On the mechanical behaviour of FRCM composites

In addition to the now-classic FRP composite materials (Fibre-Reinforced Polymer), made with long glass, carbon or aramid fibres embedded in polymer matrices (such as epoxy resins), the use of FRCM composites (Fabric-Reinforced Cementitious Matrix) is becoming more and more popular. The inorganic matrix presents numerous advantages compared to the organic one of FRPs, especially for applications to masonry constructions, given its greater compatibility with this type of substrate. In spite of their widespread application, the constitutive laws and failure mechanisms of these materials have not been adequately studied. Consequently, to date there are no agreed upon criteria for qualification of FRCM. This paper will present the results of an experimental investigation carried out in the laboratories of the Universities of Bologna, Milan and Salerno on different FRCM products available on the Italian market in order to characterize their behavior via uniaxial tensile and pull-off tests
