Review article

The paper submits the results of finite element modeling of elastic-mechanical properties of polymer composites based on fibrous fillers of carbon and glass fibers and epoxy binder under a three-point loading scheme. Numerical experiments were carried out for samples with variable thickness and gradient and symmetric with respect to the median plane content of fiber fillers in the compressed and tensile zones taking into account the different ratios of the distance between supports to thickness. There was estimated the cost of the composite. There was studied the impact of variable content and placement of fiber fillers on elastic-mechanical properties of samples. To predict the ultimate load at the allowable deflection, there was used a modeling technique based on artificial neural networks.
