Development of a tension system and influence of ultimate tension on the properties of composites

[摘要] The demand for high tension winding has increased in recently years. However, indepth studies on high-tension winding have not been conducted. In the current study, a device was developed to apply tension to the winding process, and several fibers were adopted. A new method of tension controlling tension was applied in the experiments, allowing accurate and digital control of tension in the winding. Ultimate tension (pretension) in filament winding process was evaluated. Samples with varying tension were selected for the experiment and their physical and mechanical properties were measured. Experimental results indicated that tension in winding significantly affect composites. The function of the tension was subsequently analyzed. This study concluded that the ultimate pretension in winding was far less than the fracture tension, ultimately influencing the physical and mechanical properties of composites.
