Biological damage of polymer materials can be caused by various factors, such as bacteria, fungi, insects, exposure to chemical factors and the environment. In this work, the mechanisms of damage to materials under the influence of mold fungi of the genus Rhizopus are considered. The main causes of the destruction of polymer composites under the influence of biological factors, such as degradation of the polymer matrix, the release of toxic compounds, changes in the physical and mechanical properties of composites, are analyzed. The results of the study allow us to better understand the processes of bio-damage of polymer composites and develop measures to improve their stability in various operating conditions. This is of practical importance for creating more durable and stable polymer composite materials that can be used in a wide range of applications.

This work presents the results of an assessment of the effectiveness of a polymer composition for the bioprotection of materials based on basalt fiber against fungal attack. An advantage of the proposed method is its simplicity and cost‑effectiveness, since its implementation does not require complex technological equipment or expensive components. The protective polymer composition obtained and used in the method increases the resistance of basalt‑fiber reinforced plastic reinforcement in a mycological environment and can be used to protect materials from biological damage when in contact with soil and soilborne microscopic fungi.
