A group of scientists from the Skoltech Center for Design, Manufacturing and Materials (CDMM) and University of Salerno (Italy) focused on improving pultrusion process productivity by optimizing pulling speed and structural parameters. They discovered and analyzed the interconnection between pulling speed of pultrusion and severity of manufactured induced shape distortions, matrix cracking and delaminations, mechanical characteristics. The research results are recently published in the journal Composite Structures.
In recent years, fiber reinforced polymers (FRPs) have garnered considerable interest from the engineering community, resulting in the widespread adoption of composite structures. Among the many current composite manufacturing processes, pultrusion is the most efficient, combining high production rates with low material waste.
It is well known that the construction market is highly competitive. Therefore, every manufacturer is seeking for the possibility to increase productivity while still maintaining optimum structural characteristics of the produced elements.
