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 mechanical properties composite materials with a polycarbonate matrix filled short glass inclusions. At micro-level, influence volume inclusions on designed based is studied in DIGIMAT (France) program. It was found that ratio sizes range 468÷60, particles have needle shape, material such has higher stress limit elastic modulus than shape coefficient less 50. components fiber orientation tensor were also determined, at which values are good agreement experimental data. size finite element grid characteristics macro level studied, recommendations given for choosing face element. adequacy models confirmed by field tests. testing flat samples made injection molding technology. Mechanical tests carried out three variants 10 %, 20 % 30 discrepancy between content chopped fibers explained technological factors macro-level. conducted research allowed us to develop technique used stage development polymer composites thermoplastic matrices
