The main objective of the present article is to obtain optimum technological parameters automobile plastic front-end frame. Moldflow software was used simulate injection molding frame bracket in this study. uniformity experiment designed and completed. Five process parameters, including mold temperature, melt packing pressure, time, were selected as experimental factors. Volume shrinkage warpag...

Glass-fibre reinforced polymer matrix composites exhibit superior properties to traditional materials. Thus, they have found a broad variety of applications in modern industry. For process development and quality control sophisticated three-dimensional methods for non-destructive characterization are needed. X-ray computed tomography (CT) is a powerful radiographic nondestructive-testing method...

Injection molding process is one of the most important methods of forming in the plastics manufacturing industry. Shrinkage and out of roundness are phenomenons that affect the final product quality. In this study, the effect of the thickness of cylindrical parts from polypropylene material on shrinkage and out of roundness has been investigated. For this purpose, injection molding process is s...

Conventional macro mechanical models and closed form estimates are in many cases not sufficient to appropriately predict the stiffness and strength of composite materials. Composite failure occurs as a result of complex microstructural damage mechanisms, which arise simultaneously with other nonlinear effects in the microstructure. In this contribution we propose an approach, where nonlinear ma...
