This study investigates the influence of technological factors on the dynamic mechanical properties of acoustic
composites containing natural fibers and targeted additives. Alternative binder formulations based on epoxy and
phenol-formaldehyde resins, cured without the use of toxic polyethylene polyamine, have been developed. It
was found that optimal curing regimes and the incorporation of nanomodifiers, particularly montmorillonite,
improve the vibration damping and sound insulation properties of the materials. Reinforcement with short basalt
fibers compensates for the reduction in elastic modulus. The results demonstrate the potential for creating ecofriendly,
technologically advanced, and climate-resistant composites with tailored acoustic properties.
