Abstract：This paper discusses the influence of various kinds of fibre mesh fabrics and supporting mortar on the tensile properties and bond strength of composite layers of building facades,and analyses the deterioration law of fibre mesh fabric com-posite layers of prefabricated building facades under freeze-thaw and dry-wet cycles.The study shows that different fibre mesh fabrics have different effects on the tensile properties of composite layers,and the tensile strength and elongation at break of triax-ial mesh fabric are better than that of biaxial mesh fabric in the strong and weak directions;the effect of supporting mortar on the bonding properties of composite layers is higher than that of fibre mesh fabrics,and the toughness and anti-cracking properties of the supporting mortar are strengthened to significantly enhance the tensile and bonding capabilities of fibre mesh fabric composite layers;the tensile fracture properties and bonding properties of the composite layer are easily affected by dry-wet cycles and freeze-thaw cycles,which need to be paid attention to in design and application.
