A research team in Tianjin, China, has successfully flown a drone built partly from bamboo-based composite materials. The aircraft represents what researchers describe as the first fixed-wing unmanned aerial vehicle (UAV) to use bamboo composites at this scale.

The International Centre for Bamboo and Rattan developed the drone together with Beihang University’s Ningbo Innovation Research Institute and Long Bamboo Technology Group. Their goal was to combine high-performance engineering with environmentally friendly materials.

More than 25 percent of the drone’s structure consists of bamboo-based composites. The aircraft has a wingspan of over 2.5 metres and weighs about 7 kilograms. It can take off and land vertically, cruise at speeds above 100 km/h, and fly for more than one hour.

Biobased Composite Offers Lightweight and Cost Advantages

The bamboo composite replaces conventional carbon fibre in several structural components. According to the research team, this material makes the drone more than 20 percent lighter than similar aircraft built with carbon fibre composites.

The bamboo composite also reduces production costs. Researchers estimate that the material costs around one quarter of traditional carbon fibre cloth. It is even cheaper than many aeronautical-grade composite materials.

This combination of low weight, strength and affordability highlights the potential of natural fibre composites in advanced engineering.

Developing Structural Bamboo Materials for Aviation

Lead researcher Qin Daochun explained that the team had to overcome several technical challenges. Aviation materials must meet strict mechanical standards. The researchers therefore needed to ensure high strength, durability and environmental resistance.

The team conducted more than 100 experiments to refine the material. These tests followed established airworthiness standards. The resulting bamboo-based composite offers high strength, strong toughness and good formability.

New Opportunities for Biobased Structural Materials

The successful flight shows how rapidly renewable materials such as bamboo can support advanced manufacturing. Bamboo grows quickly and absorbs carbon during cultivation. When engineered into composites, it can deliver strong structural performance.

Researchers believe the material could support the development of China’s expanding low-altitude drone industry. At the same time, the innovation highlights broader opportunities for bio-based structural materials.

For designers and engineers, bamboo composites could offer new possibilities for lightweight structures in product design, mobility systems and even architecture. As material technologies evolve, renewable fibres may increasingly replace fossil-based composites such as carbon fibre.
