Abstract
A simplified two-dimensional finite elements model was created for a polyvinyl alcohol (PVA) coated Bioglass (R) strut undergoing tensile stresses (loading mode I). The strengthening contributions due to the infiltration of coating into surface cracks and coating's stiffness were evaluated in terms of stress intensity factor K-I and tensile stresses sigma(yy) in the proximity of the crack tip. The infiltration of the coating until the crack tip resulted as the most effective criterion for the struts strengthening. Bioglass (R) based scaffolds were dip coated into PVA and PVA/microfibrillated cellulose (MFC) aqueous solutions and tested in tensile load. Coated samples exhibited remarkably higher tensile strength than non-coated ones, which further raised with the increased amount of MFC. Contact angle theta and linear viscosity eta measurements of PVA/MFC solutions showed that MFC caused a reduction in theta and a drastic increase in eta, indicating that a balance between these two effects must be achieved.
