摘要：

Three batches of unidirectional basalt fiber reinforced polymer were fabricated in the form of plates. Long tests were conducted over 365 days in a loaded state at room temperature, as well as in a closed desiccator at 99% humidity. The moisture absorption of unloaded samples in the desiccator did not exceed 0.20 - 0.23%. The residual mechanical properties of samples kept in a desiccator for 365 days were determined after the samples were dried: ultimate strain increased by 10 - 15%, elastic modulus by 14 - 21%, strength by 19 - 21%, and glass-transition temperature by 5 - 8 degrees C.
