Abstract

A comprehensive assessment of the retention of the strength properties of fiberglass VPS-68 for tension, compression, bending, interlayer shear was carried out at test temperatures of –60, +20, +80 and +105 °C in the initial state and after climatic influences in a tropical climate chamber for 1 and 3 months, thermal aging for 500 and 1000 hours, exposure to mycological environments and technical fluids. To confirm viability, samples of VPS-68 fiberglass were tested in tension and compression
