Abstract
(Fibre Reinforced Cementitious Matrix) composites cosist of PBO fobers and mineral mortar used as a matrix. It can therefore be used in places exposed to high temperatures, contrary to the systems FRP. The use of mortar, however, is associated, however, with the specific mechanics of work of this system, which significantly differentiates it from FRP systems. The performed studies have shown that in the FRCM system slippage occurs between the fibers and the matrix layer, which is associated with inaccurate coverage of all fibers by mortar and the occurrence of “telescopic effect”. The article describes the work mechanism of PBO-FRCM composites subjected to tensile and shear stresses. Three-phase work of FRCM composites and main problems associated with the use of this type of system, which is among other things premature debonding of the fibers from the matrix, were discussed.<br/><br/>
