| Carbon fiber reinforced polymer (CFRP) composites are widely used in aerospace, marine and automotive structures, where components may experience variable thermal conditions that affect stiffness, strength and load-bearing capacity. This study evaluates the influence of temperature on the mechanical properties of CFRP laminates manufactured from Gurit EP137 prepreg and tested using a universal testing machine supported by full-field Digital Image Correlation (ARAMIS/DIC). The complete set of tensile, compressive and shear properties was determined for 20–80 °C, whereas at − 20 °C only the in-plane shear modulus G₁₂ and shear strength FSU₄₅° were obtained because frosting/ icing of the chamber window and specimen surface prevented reliable DIC image registration during selected tests. Between 20 °C and 80 °C, E₁ showed an apparent increase of approximately 8.2%, while E₂ and G₁₂ decreased by approximately 34.6% and 58.5%, respectively. The tensile strength FTU₀° decreased by 28.1%, the shear strength FSU₄₅° by 41.3%, and the compressive strengths FCU₀° and FCU₉₀° by 49.4% and 43.5%, respectively. The results confirm that matrix-dominated properties are particularly sensitive to elevated temperature and provide temperature-dependent material input for subsequent numerical modelling and stability analyses of thin-walled CFRP structures. |
