The main aim of the present research was to explore the impact of chemical surface treatments of agave plant fibers on the mechanical properties of polyester resin matrix composites, such as tensile strength and impact resistance. Physical characterization techniques, such as optical microscopy, were used to evaluate fiber cross sections before and after treatments with potassium hydroxide (KOH) and a combination of KOH and aminopropyltrimethoxysilane (KOH-Silane). As well as mechanical characterization of the agave polyester composites by ASTM D3039 tensile stress tests and ISO 179-1 impact stress tests. The experimental design, with an explanatory and quantitative approach, had different concentrations for KOH treatment (1M, 2.5M, and 5M). As well as the same concentrations of KOH with a fixed concentration of aminopropyltrimethoxysilane (2M) for the consecutive KOH-Silane treatment. As results, in terms of tensile strength, greater adhesion was observed between the agave fiber and the polyester matrix by KOH. However, the addition of Silane as a coupling agent demonstrated significant bonding, further enhancing the tensile strength of the composites. This pattern was also reflected in the Charpy impact resistance results, where the addition of Silane as a coupling agent to the KOHonly treatment generated an additional positive impact, highlighting its important role in improving the toughness of the composites. In conclusion, the research highlights the effectiveness of chemical surface treatments, especially the combination of KOH and Silane, in improving the mechanical properties of polyester-agave composites.
