“…Experimental results also indicated that the average longitudinal and transverse Poisson's ratio are 0.265 and 0.114, respectively. Test results showed that the experimental value of the in-plane shear strength is smaller than the predicted value obtained in previous studies [12][13][14]. This variation may be attributed to the fact that the behavior of woven reinforced lamina is different from unidirectional GFRP lamina.…”

“…Materials models with softening behavior and stiffness degradation generally have convergence difficulties in implicit finite element method. In order to alleviate convergence difficulties, a viscous regularization scheme is adopted, and a viscous damage variable is defined by the evolution equations [14]:…”

“…19, one can notice a difference between the in-plane shear modulus and the transverse shear modulus (23-direction), while only a small difference is observed between the transverse shear strength (23-direction) and the in-plane shear strength (13direction). It is commonly accepted that in case of lack of sufficient material test data, transverse shear strength of a pultruded unidirectional GFRP lamina could be assumed to be the same as its inplane shear strength value [14]. The Mises stress, the equivalent plastic strain, and the damage distributions in the unit cell domain under transverse shear loading are presented in Fig.…”

“…Although several investigations on carbon fiber reinforced polymer (CFRP) for aerospace structures were conducted, results and outcomes of such studies are not generally applicable to pultruded composites that are commonly used in construction applications. One of the known difficulties in modeling pultruded composites accurately [14] is that pultruded composites are not precisely laminated structures due to the nature of the pultrusion process. For this reason, analytical modeling that considers the specific nature of pultruded composites is required in order to predict its thermo-mechanical performance.…”

h i g h l i g h t s A continuum damage model was implemented via user material subroutine to model fiber failure. The Mohr-Coulomb plastic criterion were used to model the epoxy behavior. The cohesive surfaces were used to simulate the fiber-matrix interface damage. Different analytical micromechanics theories were verified by the test results. Numerical homogenization methods effectively predicted the pultruded lamina macroscopic properties.

Composite specimens with resin contents of 33.5%, 35.4%, and 35.9%, respectively, were manufactured by controlling the type of subsidiary material used in the bagging process for a composite material having the same composition.The effect of controlling the resin content on the microstructure and mechanical properties of composite specimens was investigated. The flow of resin and air during the cure process was inferred and explained by connecting it with the microstructure. Specifically, the behavior of the resin determined the thickness, density, and void of the composite laminate, which acted as a factor causing the difference in mechanical properties of the composite materials. As the resin content increased, there was no significant difference in tensile strength, but Young's modulus decreased. In the case of the compression test, there was a difference in mechanical properties due to the combined effect of the reinforcement and the resin. The maximum compressive strength value was shown in the process with low void content, and Young's modulus tended to decrease as the resin content increased. In the bagging process, the subsidiary material controlled the flow of resin and air, and caused a difference in microstructure, affecting the change of mechanical properties.
