| Chemical anchors based on two-component epoxy systems are widely employed for structural fastening in composite and concrete assemblies, yet the relationship between resin–hardener ratio and mechanical performance remains insufficiently quantified. This study investigates how controlled modifications to the mixing ratios of components A (epoxy resin) and B (amine hardener) influence key material strength properties relevant to anchoring applications. A series of epoxy formulations were prepared with systematic variation in stoichiometric balance, followed by curing under standardized conditions. Mechanical characterization - tensile, compression, and material hardness -was performed to evaluate performance trends and identify deviation thresholds from optimal curing chemistry. Complementary analysis by scanning electron microscopy (SEM) provided insight into crosslink density and microstructural failure mechanisms. Results reveal a pronounced sensitivity of strength properties to component ratio, with both resin-rich and hardener-rich compositions exhibiting premature brittle failure and suboptimal interfacial adhesion. The findings underline the importance of stoichiometric control for reliability in composite anchoring systems and offer a foundation for predictive modelling of epoxy-based composite interfaces. This work bridges practical anchor design with composite materials science by linking molecular-level formulation effects to macroscale mechanical behaviour |
