Résumé : |
In straight tubes, any force applied to the cylindrical wall causes hoop stress. Tool handles, mop handles for example, experience hoop stress when being used actively or roughly handled. To ensure composite tubes can meet these challenges, the profiles must be manufactured with cross-aligned fibers, providing extra stiffness and high mechanical strength in transverse direction. Here different manufacturing techniques are compared and explored how the continuous manufacturing technology of pull-winding can achieve high hoop strength. |
