Özet
This study investigates the influence of talc particle reinforcement on the rheological, mechanical, and vibration behavior of stereolithography (SLA) photopolymer composites. Talc particles with an average size of 1–5 µm were incorporated into the resin at weight ratios of 10 wt% and 20 wt%. Rheological results show an increase in viscosity and shear-thinning behavior with increasing talc content. Mechanical characterization indicates enhanced stiffness and compressive strength, accompanied by reductions in tensile strength, toughness, and hardness, indicating increased brittleness. Vibration analyses were also carried out on the composite specimens. Based on free vibration testing, the damping ratio increased by approximately 7 % and 16 % for the 10 wt% and 20 wt% talc-reinforced specimens, respectively. On the other hand, an indirect estimate derived from normalized viscosity data yielded smaller increases of approximately 5 % and 8 % for the same compositions. The results indicate a clear correlation between vibration behavior and rheological characteristics.
