Abstract The objective of the research was to determine if basalt fiber reinforced polymer composites are feasible, practical, and a beneficial material alternative for transportation applications. No significant differences in stiffness and strength were found between basalt fabric reinforced polymer composites and glass composites reinforced by a fabric of similar weave pattern. Aging results indicate that the interfacial region in basalt composites may be more vulnerable to environmental damage than in glass composites. However, the basalt/epoxy interface may also be more durable than the glass/epoxy interface in tension- tension fatigue because the fatigue life of basalt composites is longer. A wide disagreement between the literature properties of basalt fibers and the properties measured in this study renders any further consideration of basalt reinforced composites highly problematical. Composites manufacturing issues with basalt fabric were also investigated. The measurement results of the in-plane permeability for basalt twill 3×1 fabric material showed that a high correlation exists between the two principal permeability values for this fabric. This is in contrast to the lack of correlation found in other weave patterns, and may point to an important material selection criteria for mass production of composites by liquid molding. 17.
