Low Velocity Impact Response of Carbon Fibre Laminates Made by Pulsed Infusion

Carbon fibre composites were subjected to low velocity impact tests. The scope was to investigate the response of laminates fabricated by a new vacuum assisted technology, labelled as “pulse infusion”, under dynamic loads. At this aim, experimental tests up to complete penetration and at a different energy levels, were carried out. Some of the specimens were destined to CAI tests and the residual strength was evaluated. All the parameters involved in the phenomenon, like penetration energy and indentation depths, were studied to validate existing semi empirical models. By the comparison with results from literature, good agreements were found denoting the efficiency of the new fabrication method.
