Three batches of unidirectional basalt fiber-reinforced plastic were fabricated as plates, and continued tests were performed under load at room temperature and in a closed desiccator at a 99 % moisture for 365 days. The moisture absorption
of the unconstrained specimens in the desiccator was not above 0.20 – 0.23 %. The residual mechanical properties
of the specimens that had been held in the desiccator for 365 days were measured after being dried, and the ultimate strain was found to increase by 10 – 15 %, the elastic modulus by 14 – 21 %, the strength by 19 – 21 %, and the glass transition temperature by 5 – 8 °С.
