Material compuesto frcm de cabuya: mejora de adherencia mediante la redistribución de los hilos del tejido de refuerzo

The compound materials FRCM (Fiber Reinforced Cementitious Matrix Composites) reinforced with natural fibers for the strengthening of structural elements have created great interest due to their excellent mechanical properties and their reduced cost, which has turned them into potential substitutes for composites reinforced with traditional fibers. The effectiveness of FRCM composite materials depends, among other things, on the durability of the fibers and the adhesion capacity of their components. In this study an experimental investigation was carried out about the adherence of a FRCM reinforcement system produced with cabuya weave. By not having suitable cabuya weave for composite systems of this type, which offer a satisfactory adhesion capacity, it was necessary to design and manufacture cabuya fabrics with an improved yarn configuration. The efficacy of the FRCM composite material produced with the designed fabrics of cabuya was verified through adhesion tests SLS (Single Lap Shear test) on concrete beams and pull-off tests on concrete slabs. The results were compared with those obtained in SLS and pull-off tests performed on beams and slabs reinforced with FRCM materials produced with cabuya fabrics from sacks, which have been used in several previous investigations. The results show that the adhesion capacity of the system is considerably affected by the architecture of the fabric.
