Flexural strength
The results of the mechanical tests and statistical analysis are summarized in Table 3. The flexural strength of the fractured cranioplasty and CMW-3 cured at atmospheric pressure was not significantly different, however, the flexural strength of CMW-3 cured at 2.2 bar was significantly higher than both of the aforementioned groups.
