<p>This study examines the possible substitution of sustainable basalt fibers for traditional glass fibers. The epoxy matrix has been reinforced with basalt or glass wovens, and hybrid or non-hybrid composites were fabricated via the hand lay-up/compression molding technique. The developed composite systems were characterized by thermal conductivity analysis, scanning electron microscopy (SEM) and mechanical tests. The impacts of various stacking sequences on these specifications have also been investigated. Notwithstanding an insignificant alteration in overall thickness, composites that integrate one or multiple basalt fabrics demonstrate enhanced thermal conductivity coefficients and reveal superior resistance to tensile stresses. An increase in the number of glass wovens contributes to elongation at break but decreases the ultimate tensile strength of the composite system. The deteriorative effect of flexural and compressive forces is exacerbated by an increase in the number of basalt fibers. Hybridization promotes the production of more slender composite systems characterized by reduced thermal conductivity coefficients, but it also leads to handling composite systems with unpredictable strain characteristics.</p>
