所有不起眼的材料者阿以有大用途,比如塑料坐过飞机的人都会知道,飞机的大部分零件都是由铝合金制成的,但用和铝合金一样结实耐用的碳纤维合成物与塑料来制造大飞机一直是波音公司的梦想,现在他们终于建造了一架双引擎、宽机身的喷气式飞机787,并将在2008年投入市场。虽然飞机的主要支撑骨架和前后两个机翼都使用了铝合金,但整个机身都是由合成材料组建而成。 All the obscure materialists are of great use, as is the case with plastic aircraft people who know that most of the aircraft’s parts are made of aluminum but with the same durable aluminum-carbon composite and plastic It has always been Boeing’s dream to make big aircraft and now they have finally built a twin-engine, wide-body jet 787 that will go on the market in 2008. Although the aircraft’s main support skeleton and front and rear two wings are used aluminum, but the whole body is made of synthetic materials.
