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.

。像不系安全带的行为，罚款可能会翻三倍。         根据《政府陆路交通政策声明草案》，今年下半年起不系安全带将被处以最高450纽币的罚款，而不是现在的150纽币。新的数字被认为跟英国、澳大利亚和加拿大看齐且符合通胀现实。         Advertise with us          《草案》称系安全带可以让人们在发生严重车祸时生还几率增加一倍，但每年仍有80多名道路使用者因未系安全带而死于车祸。         《草案》将对酒后驾驶和其他违规驾驶采取强硬立场——          譬如推出路边检查站，对司机的唾液进行拭子测试打击毒驾行为。目前警方只是在怀疑嗑药后进行血检，唾液检测意味着更多司机将被临检。政府的目标是每年至少唾液测试5万名司机。

C |          又譬如增设酒精测试站，打击酒驾行为。政府的目标是每年至少进行300万次随机路边呼吸检测。

D |          酒精和毒品被认为是新西兰致死车祸的两大主要原因。

E |          2022年，因司机酗酒或吸毒而导致车祸的死亡事故为163起，重伤事故为144起，轻伤事故为776起。         只有26%的司机认为自己可能会因毒驾而被抓，只有60%的司机认为自己可能会因酒驾而被抓。

F | 更重要的是，有27%的酒后肇事司机是惯犯。         总理Christopher Luxon在谈到《草案》时表示，心怀侥幸的人很多，“坦率地说这是不可接受的”。

G | 他说将斥资增加呼吸测试站点。         草案称新西兰的道路违章处罚大多拟定于1999年，之后再没有进行修改，因此远低于国际水平，在罚款力度上明显不如澳大利亚、英国和加拿大。         另外，如果被吊销驾照依然还开车上路，将面临更严厉的处罚和更多扣分。每年有6.7万名司机被吊销驾照，有约8700人因无照驾驶而被起诉。         相关阅读：          2023年新西兰进行了300多万次呼气测试，酒驾最严重的是……          过去一年里26.7万新西兰人发生过撞车事故，车险可能还要涨          又一起致命车祸，劳动节假期交通死亡人数升至4人          雪上加霜！新西兰这项生活成本将上涨20%到30%！！          保险公司呼吁车主防患于未然：当心这些常犯的错误          上周末几起车祸造成多人死亡，警方严查不系安全带、酒驾等危险行为          长周末悲剧：一系列严重车祸致四人死亡，多人重伤          长周末前ACC公布最新数据：每个劳动节都有500多人因车祸受伤          注：本文为编译/原创，欢迎转发分享；但严禁复制等未经授权的非法使用。
