1.As a result of the action of ultraviolet and ionizing radiations and thermal cycling, partial destruction of the adhesive, which causes partial removal of the polymer from the irradiated surface, and a reduction of the dynamic moduli of elasticity and the speed of sound in the glasslike state are observed in KMU-3l. In the case of shielding of the fiberglass surface with a protective film, damage of the sample surface is eliminated.2.Prolonged action of natural factors causes the appearance of additional transverse bonds due to the formation of reactive groups, a reduction of the internal stresses, and an increase in the structural uniformity of the adhesive, which results in an improvement of a number of physicomechanical indicators, an expansion of the temperature range of the work capacity, and a stabilization of the physicomechanical characteristics.3.KMU-3l fiberglass on the whole preserves for 686 days a high level of physicomechanical characteristics and a work capacity over a wide temperature range. |
