Abstract
Thermoplastic polymer alloys or composites present a structural anisotropy after injection molding. The evolution of such an anisotropy depends on the type and on the concentration of components and also on the thermodynamical conditions of processing. Thermomechanical properties of such materials evolute taking into account typical microstructures. In this paper, we study the influence of injection and mold temperatures and of injection speed on stress-strain, impact resistance and viscoelastic behaviour of 30% short glass fibers reinforced polypropylene/polyarylamide mixtures.
