一系列六个绘制管状纤维的实验与该制造过程的一些最新数学模型进行了比较。证明了纤维张力在确定纤维内部几何形状方面的重要性，证实了模型的关键预测。有证据表明内部通道具有自加压作用，其中当纤维被拉伸时，内部通道中会产生额外的压力，并且讨论了该压力大小对纤维张力的依赖性。此外，有证据表明玻璃和熔炉温度之间的差异与熔炉温度成正比，并且取决于预成型件的几何形状。
A series of six experiments drawing tubular fibres are compared to some recent mathematical modelling of this fabrication process. The importance of fibre tension in determining the internal geometry of the fibre is demonstrated, confirming a key prediction of the models. There is evidence of self-pressurisation of the internal channel, where an additional pressure is induced in the internal channel as the fibre is drawn, and the dependence of the magnitude of this pressure on fibre tension is discussed. Additionally, there is evidence that the difference between the glass and furnace temperatures is proportional to the furnace temperature and dependent on the preform geometry.
