Basalt Fiber Reinforced Polymer Composites

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.

Necessary rock studies of the gabbro and andesite basalt groups for the suitability as the raw material base for the production of continuous basalt fiber (CBF). A unique technique including laboratory melting and pilot-industrial melting at the high-tech equipment.

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.
