Effect of adding multidirectional oriented fibers on mechanical properties of denture base resin
 Kolářová, Eva ; Poláček, Petr (oponent) ; Pavelka,, Vladimír (vedoucí práce)
This Diploma thesis deals with effect of adding multidirectional oriented fibres on mechanical properties of denture base resin. Three sets of samples: PMMA resin, PMMA resin reinforced with Dentapreg Mesh and PMMA resin reinforced with stainless steel Mesh Strengthener were used for testing. Static three-point bending test and Charpy instrumented impact test were used to measure the behaviour of the samples under the static and dynamic loading conditions. Viscoelastic properties were determined by dynamic-mechanical analysis (DMA). Scanning electron microscopy (SEM) was used to characterize fracture surfaces. During the static loading of the samples the reinforcement does not play an important role in comparison with unreinforced resin. However, the opposite trend was observed under the dynamic loading where the effect to the reinforcement was increasing in the row PMMA resin – stainless steel Mesh Strengthener – Dentapreg Mesh.
