Mechanical properties
The mechanical strength of the scaffoldings was tested in a static
tensile test using the Instron 5566 apparatus. Rectangular cut out of
scaffoldings measuring 7x2 cm was tested. The samples were stretched at
a speed of 5 mm/min, and then the mean values of Young’s modulus
(E ), maximum stress (σ max), maximum
relative strain (ε max) and their standard
deviations were calculated. The analysis of each sample was done in 3
replicates.
