Effect of process parameters on mechanical properties of CFRP components obtained by filament winding process

Abstract

The present paper investigates the effect of FW process parameters, such as winding angles and process speeds, on the mechanical properties of wound Carbon Fiber Reinforced Polymers (CFRP) components. The X-Winder machine was used to realize the CFRP tubular parts with different winding angle values (30°, 60°, 90°) and process speeds, obtained varying the combination of the carriage and mandrel speeds. To investigate the mechanical properties of the wound components, rings specimens were obtained from the tubular structures by cutting operations and tensile tests were performed according to the ASTM D2290 international standard. The results show that an increase in the winding angle leads to a relevant improvement in tensile properties; whilst a slight rise in those properties can be achieved by increasing the process speeds.
