Composite truss core sandwich structures have the significant advantage in astronautic and aeronautic applications owing to their high specific stiffness and strength. In recent years, different composite sandwich panels have been designed, tested, and analyzed. The mechanical properties of composite materials may suffer when the material is exposed to high temperature, high humidity environments. Glass fiber reinforced plastics composite is extensively used as a structural material for pools, oil pipes and tanks because it has good corrosion resistance properties. In this work, the effect of temperature on PVC/PVC sandwich plates having 0.95 Wt.% glass fiber blended with different types of adhesives (epoxy, polyester, and polyvinyl chloride) is studied. Different temperatures (35 oC, 45 oC, 55 oC, 65 oC and 75 oC) as well as three times of exposure (2 hrs.,4 hrs. and 6 hrs.) is adopted. The mechanical properties such as tensile strength, ultimate strength, modulus of elasticity, energy to fracture, impact energy and adhesion shear at different temperatures are studied. The activation energy of PVC /PVC sandwich plates having glass fiber as reinforced material blended different adhesives was studied It has been found that the mechanical properties of PVC /PVC sandwich plates having 0.95 Wt.% glass fiber blended with different types of adhesives the mechanical properties are affected by temperature. In addition, it has been found that the activation energy of PVC /PVC sandwich plates having glass fiber as a reinforced material blended with polyvinyl acetate is the largest compared with epoxy and polyester.
