Bending test and simulation of carbon fiber aluminum honeycomb sandwich structure

Abstract

Abstract According to the bending moment characteristics of carbon fiber aluminum honeycomb sandwich structure for the solar wing in use, this paper simulates and analyzes the large-scale bending samples and tests the bending samples at room temperature, 150 °C, and -150°C. The test results show that the bending performance is not different between low-temperature environment and room temperature environment, but the stiffness and strength at high temperature are reduced by 54.9% and 50%, respectively, compared with room temperature. Compared with the room temperature test results, the simulation results are about 10%, which can roughly reflect the bending performance characteristics of sandwich structures.
