SIMULATION AND TEST FOR THE LIGHTNING DAMAGE OF THE GLASS FIBER COMPOSITES

Abstract

Abstract: Theoretical deducing, simulated lightning test and finite element simulation are used to investigate the mechanism and state of lightning damage of the aircraft composite sandwich panels. It provides the basis for the design of the aircraft lightning protection. The three-dimensional finite element model of the composite board is constructed through the thermal-electrical-mechanical multi-physics coupling field. According to the structure and the role process, the lightning effect of the aircraft composite is analysed to study the damage mechanism and the possible state of the composite plate that is struck by lightning. The impact current generator is used to carry out the simulated lightning test to observe the lightning effect of the composite panel. By comparing the test results and the simulation results, the effectiveness of the simulation approach and the correctness of the simulation results are verified.

Key words: composite materials, finite element, multi-physics coupling field, numerical simulation, simulated lightning test
