摘要：

The main purpose of this research work is to study the effect of glass particles addition into poly (epsilon-caprolactone) (PCL) matrices. Poly (epsilon-caprolactone) (PCL) and composite Polycaprolactone/TCP20 Bioglass (80/20 wt% and 65/35 wt%) scaffolds were produced by using an extrusion-based process called BioExtruder. The structures were characterized regarding the morphological and mechanical properties, in order to investigate the effect of BG addition in the polymeric scaffolds. Morphological properties show that all scaffolds feature a well defined internal geometry and uniform pore distribution. Concerning mechanical properties it can be concluded that bioglass strongly reduces the performance of PCL scaffolds under compressed loads, as expected due to different character of both materials. Therefore, it is predicted that the scaffold degradation becomes easier, which is also important when implanted in the human body.
