“…The fibre-reinforced material investigated in this study (EVX) yielded the highest VHN at base line measurements which could be related to the short glass fibres incorporated in their filler system as this was supported by previous studies that showed a comparable increase mechanical properties compared to the other commercial composites [57,58]. The effect of solvents on the VHN of this material after 90 days was 30% reduction in water and 51% in ethanol and 55% in MEK.…”

“…This reduction in VHN can be explained by the potential deteriorative effect of solvents on the interfacial adhesion between the matrix and the glass fibres. Fibre-reinforced composites absorb more water than conventional composite, which is related to the hydrophilicity of the polymer network and the reduced stability of the filler particle in the solvent [15,57,59,60].…”

“…The major difference in this material is the nature of its filler system which is based on short glass fibers. Glass fibers were added for the purpose of improving the strength of the material and prevention of crack propagation [67,68]. On the contrary, in this study EVX showed the lowest elastic modulus compared to the other tested materials.…”

“…Amplamente empregada em testes laboratoriais de compósitos odontológicos 19,20,60,80,[92][93][94][95] a resistência à flexão é um bom parâmetro para avaliar a resistência de um material à fratura 96 . O teste geralmente utiliza espécimes de secção retangular posicionados sobre dois apoios, onde uma força constante é aplicada verticalmente, gerando tensões de compressão na superfície diretamente em contato com a força e tensões de tração na superfície oposta a essa até a ruptura do corpo de prova 97 .…”
