Mechanical Properties Analysis of Carbon Fiber Panels Sandwich Structure Containing Aluminum Alloy Corrugated Core

Abstract

Carbon Fiber Reinforced Polymer (CFRP)is widely used in industry and construction. In this paper, three-point bending test was used to analyze the mechanical properties of CFRP by introducing aluminum alloy corrugated core. The numerical simulation is fairly consistent with the experimental analysis. We found that more than 95% of energy consumption comes from corrugated cores. The attenuation of bending failure stress is 38.83%. It fully shows that corrugated core has outstanding buffer capacity for objects hitting. In addition, two kinds of material are bonded by the adhesive. We also found that increasing the thickness of the adhesive will reduce the contact stress, enhance the stability of the structure and promoteelastic-plastic damage deformation.
