- Abstract: Regarding the aircraft takeoff and landing from high altitude at the constant and low-temperature, this paper will focus on the root facture problem of carbon fiber reinforced polymers (CFRP) material of aircraft winglet through ABAQUS simulation analysis, experimental analysis, and topography analysis. The innovative purpose of this paper is to identify the critical failure stress of the cantilever bending of unidirectional and orthogonal, embedding carbon nanotube reinforcement, and exploring the embedded carbon nanotube regarding the enhancement effect of CFRP aircraft winglet. First of all, the analysis of the force state of the aircraft winglet, the unidirectional and orthogonal CFRP aircraft winglet at normal temperature, and low-temperature cycling are established based on the principle of classic laminates and statics. The wing cantilever bending critical failure stress mechanics model provides a theoretical basis for the influence of low-temperature cycles on aircraft winglets. Secondly, verifying the correctness of the above-mentioned mechanical model, the CFRP aircraft winglet was studied through bending stress analysis, stress-displacement curve analysis, and sample topography analysis. Finally, the equipment for preparing embedded carbon nanotubes CFRP composite material was designed to ensure the accuracy of the test piece and explored the effect of embedded carbon nanotubes on the CFRP aircraft winglet. The enhanced result of the cantilever anti-bending ability and the microscopic mechanism of action provides the basis of the carbon nanotube reinforcement medium to the CFRP aircraft winglet development. Keywords: Aircraft Winglet, CFRP, Cantilever Bending, Low-Temperature Cycle, Laying Angle, Carbon Nanotube Reinforcement.
