Development and verification of mechanical characteristics of a composite material made of a thermoplastic matrix and short glass fibers

The paper presents the results of computer modeling and prediction of the mechanical properties of composite materials with a polycarbonate matrix filled with short glass inclusions. At the micro-level, the influence of the volume of inclusions on the mechanical properties of the designed composite...
