Effects of Environmental Factors on Composite Materials in Airframe Structures of Long Endurance Unmanned Aerial Vehicle

The damage of composite materials in airframe structures of long endurance unmanned aerial vehicle under service condition was discussed from effects of environmental factors on composite materials, influences of high aspect ratio structure, etc. Based on research status at home and abroad, the main demand in researching influences of environmental factors on composite materials in the airframe structures of long endurance unmanned aerial vehicle were summarized. Suggestions for future research works were put forward, including: select the carbon fiber reinforced resin matrix composite materials and coatings system in the airframe structures of long endurance unmanned aerial vehicle as research objects, carry out exposure testing along with the unmanned aerial vehicle and laboratory simulation accelerated testing, study the change of mechanical properties of the composite materials under the co-effect of environment and load, and identify the damage rules of the typical composite materials in the airframe structures.
