Composite Laminate Deflection during Low-velocity Impact

Popis výsledku v původním jazyce

For the development of a composite structure damage detection system, it is important to create a reliable numerical predictive model of the damaged material. This paper is focused on experimental and numerical analysis of a drop weight impact test and the possibility of its extension by the presence of a laser interferometer for deflection measurment. The subject of the test was 1.58 mm thick composite laminate made of a commercially inaccessible carbon fibre-reinforced epoxy matrix. The impact test was simulated with the help of ABAQUS/Explicit 6.14 solver and compared with the experiment. Results of the laminate deflection were statistically assessed showing 4% difference between the model and the experiment.
