Abstract

Fabric-reinforced cementitious matrix (FRCM) composites often include polymer-impregnated bundles to
improve the exploitation of the textile mechanical properties. However, organic components may degrade when
exposed to elevated temperature. In this paper, the bond behavior of a carbon FRCM applied to a masonry
substrate and exposed to a thermal preconditioning up to 300 ◦C for 250 min is investigated. Tensile tests on the
textile and flexural and compression tests on the mortar matrix, as well as single-lap direct shear tests of FRCMmasonry joints with bare and impregnated textiles, are performed. Results show that the polymeric impregnation
improves the mechanical properties of the FRCM even after thermal preconditioning.
