The drone has completed multiple test flights, China Central Television (CCTV) News reported.
Long Bamboo, a company based in East China's Fujian Province, developed the technique that preserves the bamboo's tough outer layer and allows different parts with different densities of the material to be used according to their properties, improving its overall performance.
In the past, the outer skin of bamboo was often treated as leftover material and eventually burned into low-value bamboo charcoal.
According to a company release in February, bamboo-based composites now make up more than 25 percent of the entire drone, while its fuselage skin is made entirely from the company's own high-performance bamboo composite material.
The bamboo-based material also offers a major cost advantage, costing only about one-quarter to one-tenth as much as aviation-grade carbon fiber. After the drone is retired, the material can naturally degrade, allowing it to effectively "come from nature and return to nature."
The team spent four years building data models, upgrading equipment and refining the material. The resulting drone has a wingspan of more than 2.5 meters but weighs only about 7 kilograms, and has already completed multiple test flights, according to CCTV News.
Bamboo was traditionally used mainly in products such as tableware and furniture. Now, however, the material is finding its way into a wider range of industrial applications. Bamboo fiber is being used in automobile interiors, while bamboo-based materials are also being explored as possible substitutes for plastics, glass fiber and carbon fiber in some applications. 
China has the world's largest bamboo resource base, with about 7.56 million hectares of bamboo forests nationwide. The country also ranks among the world leaders in bamboo resources, bamboo cultivation technologies and the development and utilization of bamboo materials, per CCTV News.

二 | 自欧冠被拜仁淘汰出局后，勒沃库森在各个战线似乎都受到影响，表现不佳。

在欧冠1/8决赛首回合0-3不敌拜仁后，回到德甲，药厂0-2不敌不莱梅。此后，在四月初，勒沃库森先是在德国杯爆冷不敌德丙球队比勒菲尔德无缘决赛，此后三轮对阵德甲下游球队，先是依靠绝杀艰难击败海登海姆，此后遭遇2连平，积分形势进一步被拜仁拉大。若下一轮拜仁赢球，勒沃库森无法取胜，拜仁将提前夺冠。

勒沃库森近九轮战绩↓
