PREPARATION AND PERFORMANCE EVALUATION OF CELLULOSE–BASALT FIBER HYBRID COMPOSITES FOR THERMAL AND ACOUSTIC INSULATION

This study presents the development of cellulose–basalt fiber hybrid composite materials for thermal and acoustic insulation applications using cellulose derived from agricultural biomass. The composites were fabricated through mechanical mixing and compression molding, and their physical, mechanical, and structural properties were investigated. The results demonstrated strong interfacial bonding between the cellulose matrix and basalt fiber reinforcement, leading to the formation of a stable porous structure. The developed composites exhibited low density, satisfactory mechanical strength, good thermal insulation, and effective sound absorption performance. These environmentally friendly materials, produced from renewable resources, show considerable potential as sustainable insulation materials for modern construction and engineering applications, contributing to improved energy efficiency and reduced environmental impact.
