Abstract
Composites have been found to be the most promising and discerning material available in this century. Fiber-reinforced plastic is a composite material wherein a polymer is reinforced with fibers to enhance or add properties. These fibers are typically glass or carbon, although aramid, basalt, and even wood and paper have been used. Fiber reinforced plastics are commonly used in aerospace, automotive, marine, and construction industries because of their corrosion resistance and low weight-to-strength ratio.
In this work, the effect of acidic , alkaline and neutral mediums on the PVC / PVC sandwich plates with 0.95 Wt. % glass fiber blended with different types of adhesive materials (epoxy, polyester and poly vinyl acetate) were studied deeply. Different pH values (3, 5, 7, 9 and 11) as well as three time of exposure (2 hrs., 4 hrs. and 6 hrs.) were adopted. The mechanical properties of the PVC / PVC sandwich plates with glass fiber blended with different types of adhesive materials such as tensile strength, ultimate strength, modulus of elasticity, energy to fracture, impact energy and adhesion shear at different pH values were studied.
It has been found that the mechanical properties of PVC / PVC sandwich plates with 0.95 Wt. % glass fiber blended with different types of adhesives decrease with increasing the time in both strong alkaline medium, acidic medium and is constant in neutral medium.
