Mechanical study of PLA-PCL fibers during in vitro degradation.
The aliphatic polyesters are widely used in biomedical applications since they are susceptible to hydrolytic and/or enzymatic chain cleavage, leading to α-hydroxyacids, generally metabolized in the human body. This is particularly useful for many biomedical applications, especially, for temporary mechanical supports in regenerative medical devices. Ideally, the degradation should be compatible ...
متن کاملNanoindentation of injection molded PLA and self-reinforced composite PLA after in vitro conditioning for three months.
Poly(lactic acid) (PLA) is used for medical devices such as sutures or orthopedic screws. A standard way to determine the loss of mechanical properties of a degradable polymer would be to soak the polymer in phosphate buffered saline (PBS) and test the desired property as a function of immersion time. This method is not sensitive enough to discern changes in mechanical properties through the cr...
متن کاملEnzymatic degradation behavior of nanoclay reinforced biodegradable PLA/PBSA blend composites.
Films of a biodegradable PLA/PBSA blend and blend-composites containing 2wt% of C20A, C30B and MEE were prepared by solvent casting and spin coating. The films were incubated in vials containing Tris-HCl buffer with Proteinase K, and their weight losses were measured after enzymatic degradation. The surface morphology before and after degradation tests was studied by SEM and in situ AFM. The re...
متن کاملin vitro evaluation of veneering composites and fibers on the color of fiber-reinforced composite restorations.
color match between fiber-reinforced composite (frc) restorations and teeth is an imperative factor in esthetic dentistry. the purpose of this study is to evaluate the influence of veneering composites and fibers on the color change of frc restorations.glass and polyethylene fibers were used to reinforce a direct microhybrid composite (z250, 3m espe) and a microfilled composite (gradia indirect...
متن کاملFlexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers
The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
