MECAPROTEC公司成功研制了一种由金属空心球组成的材料。新材料成为保护驾驶舱“蜂窝”的竞争对手。它在机械方面，声学方面，强化学环境保持良好惰性，承受-100到+1000℃温度，有多种加工方式（拼接、焊接）。可用于抵御冲撞、子弹的结构，可用于发动机舱，处理空气入口的噪声
MECAPROTEC successfully developed a metal hollow ball consisting of material. The new material becomes a competitor in the cockpit “honeycomb.” It is mechanical, acoustical, strong chemical environment to maintain a good inertia, to withstand -100 to +1000 ℃ temperature, a variety of processing methods (splicing, welding). Can be used to counteract the impact, bullet structure, can be used for the engine compartment, handle the air inlet noise
