The glass fiber can change the mechanical properties of the material .

玻纤可以料的机械性能。

The glass fibers tend to orient in the flow direction

玻纤倾向于流动方向上取向。

Now imagine doing that millions of times faster down a tiny glass fiber, across  an entire ocean and you've got the right idea.

现想象一下， 沿着一根微小的玻纤维， 以数百万倍的速度穿过整个海洋，你就得到了正确的想法。

The team have worked out how to minimize cost by using carbon fiber rebars only where strictly necessary In other places they use glass fiber which is cheaper.

团队已经研究出如何通过格必要的情况下使用碳纤维钢筋来降低成本，其他地方他们使用更便宜的玻纤维。
