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.

。维修人员计划在本周确定故障点，着手开展维修工作。截至当地时间13日下午，该国相关部门仍未发布地震灾情的评估报告。迄今所知受破坏最严重的地区是莫罗贝省、东高地省和马当省。

二 | 地震引发了山体滑坡等次生灾害，对这些省份的建筑物和公共道路造成了破坏。当地人员伤亡情况仍不明。政府派出的直升机正在对偏远地区和农村灾区的受灾情况进行评估。在总理马拉佩的要求下，巴布亚新几内亚政府在11日地震当天成立了国家指挥中心，成员包括警察、国防军和其他相关政府机构的官员和专家。国家指挥中心正在汇总各方面信息，根据各地区灾情，确定并实施相应的救援行动。综合当地媒体报道，当地时间9月11日9时46分，巴布亚新几内亚东部地区发生7.6级地震，震中在莫罗贝省和马当省交界的马克汉姆山谷地区。当天10时42分，在距离第一次地震震中70公里处，又发生一次5.0级地震，震源深度为地下101公里。
