Abstract

Filament wound (FW) structures present a geometric characteristic in their helical layers: the winding pattern. The pattern, however, is usually disregarded in conventional experimental or numerical approaches even though it can affect the behavior of FW structures, and most studies that account for the pattern are only theoretical. This study aims at deepening the understanding of pattern effects via a comprehensive experimental campaign focusing on composites cylinders under radial compression. Ten winding patterns were considered, from 1 to 10 units along the circumferential direction. Strength, stiffness, absorbed energy and failure mechanisms were evaluated. The results show that the pattern may have a strong influence on both maximum bearing load and absorbed energy, whereas stiffness is less affected.
