We can also note, from the porosity values reported in table , that the standard deviation values of the porosity are small (less than 1%). Porosity differences between similar samples have two possible origins: differences in the amount of porosity in the ice-templated ceramic scaffolds, and different outcomes of the polymer infiltration procedure (repeated in some cases up to 8 times). Icetemplating is a robust approach: when the same suspension is frozen under the same conditions to prepare several samples, the final porosity range (after drying and sintering) is narrow, typically within 1% . This value is similar to the values measured in the final composites, which therefore indicate that the polymer infiltration procedure is quite robust too, and produce consistent results between samples infiltrated in similar conditions. Some fracture events may occur before the maximum stress is reached, leading to the stochastic shape of the compression curve. These events are most likely caused by the fracture of the internal struts in the porous structure. Both PCL-infiltrated scaffolds (1 and 4 infiltration cycles) show a linear elastic behavior in the first stage, similar to non-infiltrated samples. However, once the ceramic is broken (at the end of the linear elastic region), polymer-infiltrated scaffolds exhibited a plastic stage (plateau) at a load level which depends on the amount of polymer in the porous composite. This effect is also quantified by the work of fracture differences obtained in each infiltration condition at a similar strain value of 7% (as calculated using the linear elastic assumption) (Tab. 2).
