![]() ![]() Then, ballistic impact tests were performed on solid plates using a gas gun with 9 mm spherical steel projectiles at velocities ranging from 95 m s -1 to 120 m s -1. Further, dynamic mechanical analysis was conducted under a frequency sweep at room temperature to examine the viscoelastic properties the material exhibited high elastic behaviour. ![]() Based on these tests, the material’s deformation and fracture behaviour can be considered elastic-brittle. Quasi-static tensile and compression tests were carried out based on ASTM standards to characterise the elastic-plastic properties of the manufactured material. Nylon reinforced with short carbon fibres was selected, and fused deposition modelling was used to fabricate solid quasi-isotropic structures. The aim of this research is to investigate the dynamic fracture behaviour of AM polymer composites under ballistic impact. While many studies focused on quasi-static performance of AM materials and structures, investigations on the dynamic performance of these materials are still limited, especially for polymers and composites. ![]() ![]() Recent technological advancements led to active research in the field of additive manufacturing (AM) thanks to its ability to fabricate complex structures with reduced material waste. ![]()
