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.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

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.
