Corrosion and Aging of Glass Fibers and Glass Fiber-Reinforced Thermosets

Under the influence of weak acids occur in glass fibers and glass fiber reinforced plastics, corrosive effects in the form of spiral and linear cracks. It is important to distinguish between mantle and core. When making the fiber internal tensile stresses arise in the outer shell. By the leaching of various glass components material losses occur and form the spiral and linear cracks. The action of aggressive media environment also causes a change in glass fiber reinforced thermosets in mechanical properties. By diffusion through the matrix and particularly along the glass fibers irreversible damage.

The leaching and cracking process in the fibers leads to significant changes instatic and dynamic material properties. The residual strength level lies at a level that ensures security of components produced there from with careful design and dimensioning in no case more.
