Damage sequence of impact events on 3d-printed composite laminates with quasi-static indentation test

Abstract

Additive manufacturing techniques are nowadays common in many industrial sectors due to their versatility, fast product development and reduced cost. Although at a different level of use, quick and easy manufacturing of lightweight composite parts, facilitates the introduction of additive manufacturing in aerospace and automobile industries. However, this type of components are susceptible of receiving impacts during their service-life. While this can be one of the most compromising events for the integrity of the structure, there has been little research conducted on the response of 3D-printed composites against impact. In fact, the analysis of the damage mechanisms and sequence taking place in 3D-printed composite laminate during a low-velocity impact event is a key factor for a wider use of this type of materials. As for any other type of laminate, this knowledge will lead to more accurate numerical modelling, improving designs and reducing material weight and costs
