Abstract
The paper studies the mechanical properties of glass fibre reinforced polymers (GFRP) with various types and orientation of reinforcement. Analyzed specimens manufactured in the infusion process are made of polymer vinyl ester resin reinforced with glass fibres. Several samples were examined containing different plies and various fibres orientation [0, 90] or [+45, –45]. To assess the mechanical parameters of laminates, a series of experimental tests were carried out. The samples were subjected to the uniaxial tensile tests, which allowed us to obtain substitute parameters, such as modulus of elasticity or strength. After all, results from experiments were used to validate the numerical model. A computational model was developed employing ABAQUS software using the Finite Element Method (FEM). The analysis was performed to verify and compare the results obtained from numerical calculations with the experiments. Additionally, the following failure criteria were studied, based on the index of failure IF Maximum Stress, Maximum Strain, Tsai–Hill, and Tsai–Wu. The results confirmed the assumptions made for the footbridge's design purpose, which is made using examined material. Moreover, comparing the experimental and numerical results found that in the linear-elastic range of the material, they are consistent, and there is no significant difference in results.
