Fiberglass Reinforced Plastic (FRP) composites are extensively used in maritime applications due to their high strength-to-weight ratio, corrosion resistance, and adaptability complex designs. However, the effects of operational thermal conditions on FRP’s viscoelastic properties fatigue life remain understudied, particularly tropical environments. This study focuses determining temperature range for Dynamic Mechanical Analysis (DMA) testing by analyzing distribution an FRP patrol vessel operating Bangka Belitung waters. Thermal simulations using Ansys Steady State Finite Element (FEA) identified critical zones vessel. The maximum temperature, approximately 70°C, was observed near engine bulkhead stern area. this load-bearing regions experiencing significant mechanical stresses, where temperatures between 35°C 45°C. These values were selected DMA evaluate behavior under operationally relevant conditions. results highlight how localized gradients affect structural performance provide input parameters future studies. By integrating analysis with selection ranges, offers a robust framework enhance design reliability vessels

The object of research is cured thermosetting epoxy polymer and FRP on the base same matrix. purpose this to develop finite element (FE) method in modeling polymers FRPs predict their mechanical thermal properties. structural mathematical with subsequent computer FE was performed. results were compared experimental data polymer's FRP's tensile strength deformations under load at different temperatures. design model based tetrahedral supramolecular structure then transformed into by integrating glass fiber rods. Using density as model's parameter, relative size disposition elements determined. viscoelastic properties are set regulating compressive/tensile joints. long-term plastic deformation stress relaxation determined result structure's inner shearing decrease its density. models developed, making it possible short-term high accuracy considering temperature factor.
