| Abstract [eng] |
Hybrid composites that incorporate synthetic fibers, such as glass, aramid and carbon, offer a balance of high strength, reduced weight and cost-effectiveness, making them highly applicable across various industries [1, 2]. This research focuses on numerical investigation of the tensile properties of these hybrid composites, with particular emphasis on the effects of stacking sequences on mechanical performance. Two configurations of hybrid laminates were simulated and analyzed, with different sequences of aramid and carbon fiber reinforcements arranged symmetrically in woven mat forms. This study uses a detailed finite element model to predict the tensile response of each configuration, allowing optimization of stacking arrangements for maximal tensile strength and durability. By comparing the numerical simulation results with experimental data found in the scientific literature [3], the research establishes a robust framework for analyzing and predicting the performance of synthetic fiberbased composites in applications requiring specific strength and durability. In this research, FEM code ABAQUS was used for the numerical simulation of tensile test. Few models of tension specimens with different stacking sequence layer arrangements of different fibers were created. Using the developed models, the tension test was numerically simulated. As the simulation result, the stress-strain curves were determined. The validation of numerical simulation was achieved by comparing modeling results with experimental test results [3]. The comparison revealed a good coincidence between simulation and experimental results. |
