工程师还可使用会发出声波的探测器，来检查复合材料的结构。

Engineers can also use acoustic emission sensors on composite structures.

一位没有参与该项目的工程师推测，最理想的选择，碳纤维复合材料结构对于中行商发来说太难了。

An engineer not involved in the project supposes that the ideal choice, carbon-fiber-reinforced composite, would have been technically too difficult for ACAE.

我们的车架从构思，测试到完善，37名碳纤维工程师全情投入，其中包括11位复合材料工程学专家以及9位火箭科学家。(火箭科学家？是的，因为航空航天工业是碳纤维技术创新的温床。)

Our frames are imagined, tested, and perfected by our 37 carbon engineers, including 11 Conposite Materials Engineering specialists and 9 bona fide rocket scientists. Why rocket scientists?
