Abstract

Fiberglass–rigid polyurethane foam (RPUF) sandwich panels are widely applied in marine structures because they combine lightweight construction, thermal insulation, and structural efficiency. However, variations in RPUF density and low environmental temperature may affect the thermal contraction and structural response of the panel. This study investigates the thermal and structural behaviour of a fiberglass–RPUF sandwich panel using the finite element method in ANSYS Workbench. The panel consists of two fiberglass skins and an RPUF core, with constant geometry and layer thicknesses throughout the analysis. Four RPUF densities of 30, 40, 60, and 80 kg/m³ were evaluated under four ambient temperatures of −40, −80, −120, and −160°C, producing sixteen simulation cases. A film coefficient of 10 W/m²·K was applied to the bottom surface in the Steady-State Thermal analysis. The resulting temperature field was subsequently transferred into Static Structural analysis using Imported Temperature. The evaluated outputs included total deformation, directional deformation, maximum and minimum thermal strain, and equivalent stress.
