制造这种物质，该小组把原料石墨磨碎，用化学品净化，把它重塑成“纳米结构”，然后再把它加工成纸张。

To make the material, the team milled raw graphite by purifying it with chemicals to reshape it into 'nano-structured configurations' which are then processed into sheets of paper.

现在我们有机会利用石墨薄膜来制造更轻更牢固的碳纤维，进而让我们的飞机更轻更安全。

Now we have the opportunity to use graphene to make even lighter and stronger carbon fibres and so make our aircraft even lighter and stronger.
