| Popis: |
The article presents the results of studies of the properties of carbon fiber of the VKU-51 brand and fiberglass of the VPS-58 brand, made on the basis of the epoxy vinyl ester binder of the VSV-43 brand, after exposure in full-scale conditions of moderate and subtropical climate for 5 years with intermediate removals after 1 and 3 years. Physical and mechanical characteristics (strength and modulus of elasticity under tension, compression and bending) and glass transition temperature are determined. Studies have shown a high preservation of properties at 20 °C: 90–100% in VKU-51 and 73–100% in VPS-58, depending on the type of test. |
