“…The technological advances in various sectors have created demand for newer materials, where they are required to perform in stringent conditions (high pressure and temperature, highly corrosive environments, with high strength requirement), which the conventional materials failed to service. Industry has recognized the ability of composite materials to produce high quality, durable and cost-effective products [1][2][3][4].…”

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.

“…However, materials in industrial applications are subjected to not only static but also dynamic loads, probably both at the same time, or both occurring sequentially [ 32 ]. Therefore, it is of great importance to study the combination of the dynamic and static studies of propellants to achieve the inter-conversion of the relaxation modulus and dynamic modulus [ 33 , 34 ], so that dynamic and static experiments or simulations can mutually corroborate. So, how can the numerical conversion of the dynamic storage modulus and relaxation modulus in engineering applications be realized?…”

As a typical viscoelastic material, solid propellants have a large difference in mechanical properties under static and dynamic loading. This variability is manifested in the difference in values of the relaxation modulus and dynamic modulus, which serve as the entry point for studying the dynamic and static mechanical properties of propellants. The relaxation modulus and dynamic modulus have a clear integral relationship in theory, but their consistency in engineering practice has never been verified. In this paper, by introducing the “catch-up factor λ” and “waiting factor γ”, a method for the inter-conversion of the dynamic storage modulus and relaxation modulus of HTPB propellant is established, and the consistency between them is verified. The results show that the time region of the calculated conversion values of the relaxation modulus obtained by this method covers 10−8–104 s, spanning twelve orders of magnitude. Compared to that of the relaxation modulus (10−4–104 s, spanning eight orders of magnitude), an expansion of four orders of magnitude is achieved. This enhances the expression ability of the relaxation modulus on the mechanical properties of the propellant. Furthermore, when the conversion method is applied to the dynamic–static modulus conversion of the other two HTPB propellants, the results show that the correlation coefficient between the calculated and measured conversion values is R2 > 0.933. This proves the applicability of this method to the dynamic–static modulus conversion of other types of HTPB propellants. It was also found that λ and γ have the same universal optimal value for different HTPB propellants. As a bridge for static and dynamic modulus conversion, this method greatly expands the expression ability of the relaxation modulus and dynamic storage modulus on the mechanical properties of the HTPB propellant, which is of great significance in the research into the mechanical properties of the propellant.
