Composites reinforced with synthetic fibers generate environmental pollution problems throughout their useful life, because they are not easily recyclable, much less biodegradable. For this reason, natural fibers have been considered an ecological alternative; however, they cannot be used as reinforcement in their natural state due to their compatibility with polymer matrices. To improve this property, the fibers are subjected to chemical treatments such as mercerization, salinization, etc. However, these treatments have a negative impact on the environment and people’s health. For all the above, this thesis project proposes the study of the physical/mechanical properties of cabuya fiber subjected to a treatment using sodium bicarbonate, in addition to studying its interfacial compatibility with thermosetting matrices to be considered it as a reinforcement of this type of matrices in composite material, thus reducing pollution environmental and giving added value to fibers as raw material. Initially, the mechanical properties of the fibers will be determined at different treatment times. The evaluation of the mechanical properties of the interaction between the fiber and the matrix will be carried out with experimental method called pull out test and will be validated using computational mechanics. As a result, better mechanical properties were obtained in the fibers treated for 7 days where the stress, elastic modulus and strain found are 744 MPa, 28.775 GPa and 0.037 mm/mm respectively. Similarly, the optimal results in the interfacial test were with the previously mentioned fibers embedded in epoxy resin where an interfacial shear stress of 6.30 MPa was obtained; in addition, the computational model was validated with a difference of less than 5% in the mechanical properties.
