The higher the temperature, the lower the critical fiber volume fraction.

温度越高，临界纤维体积分数越低。

The experimental results show that the compressive strength and split tensile strength have different increases as the fiber volume fraction increases.

试验结果表明，随着碳纤维质量百分数的增加，水泥砂浆的抗压强度和劈裂抗拉强度都有不同程度的提高。

Under the same deposition condition, the porosity of composites with 40% fiber volume fraction is a little bigger than that with 30% fiber volume fraction.

同样沉积条件下，纤维体积含量40%的复合材料与含量为30%的复合材料相比，气孔率略大。

In the mid-1990s Ciena, Lucent and Nortel introduced boxes that vastly increased the volume of data a fiber can carry.

For the last ten years, as the volume of content sloshing through fiber around the world is exploded, Denton led a revolution in savage drive-by snark that, though pretty much standard fare in countries like the U.K., induced rubbernecking whiplash for American readers.

It has a joint venture with Teijin, a Japanese company, to develop high-volume production methods for lightweight carbon fiber to improve fuel economy.
