Analytical and experimental comparison of basalt and carbon fibers composites overwrapping of highly pressurized steel cylinders

This paper provides theoretical background, results of laboratory measurements and AE tests for the mechanical behavior of the composite reinforced metal cylinder subjected to pressure load of 200 MPa.

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.

Two types of composite fibers were compared, basalt and carbon fibers. At high loads, the composite reinforcement is found to effectively support the metal tube when the steel material approaches plastic yielding.

This phenomenon has been clearly visualized by AE signals, appearing in the frequency range between 280kHz and 450kHz. It was concluded, that cheaper basalt roving can be safely used in the analyzed application.
