But aramid molecules are super rigid, more like steel-reinforced dry spaghetti.

但是芳纶分子非常坚硬，更像是钢筋加固的干意大利面条。

And that meant finding the right chemical to get in between the aramid molecules and separate them.

这意味着找到合适的化学物质进入芳纶分子之间，并将它们分离。

Flat, hexagonal structures in the molecule called aromatic rings keep individual aramid molecules relatively rigid and make them resistant to heat.

分子中称为芳香环的扁平六边形结构使单个芳纶分子相对坚硬，而且也赋予了它们耐热的特性。

They're made with a combination of proprietary synthetic rubber compounds, which are paired with aluminum steel reinforcements and nylon and aramid fabrics.

它们是由专用合成橡胶化合物与铝钢增强材料以及尼龙和芳纶织物组合而成的。
