“…The study of new materials with good performance and low cost has led to the use of vegetable fiber reinforcement in substitution totally or partially to the reinforcement of synthetic fibers [1]. In this context, the use of vegetable fibers as reinforcement in polymeric composites has received much attention from researchers due to the fact that vegetable fibers have characteristics and advantages such as: low density, good strength, low abrasiveness to process equipment, they are not toxic or polluting, reducing this way environmental problems, as well as are originating from renewable sources and available worldwide [2][3][4][5]6].…”

In this work was conducted a theoretical and experimental study of water absorption in polyester matrix composites reinforced with sisal fiber at temperatures of 25, 50 and 70°C. A fiber content 44.6% sisal fibers, and 55.4% polyester matrix were used in the manufacture of the polymer composite. The dimensions of the composite were 20x20x3mm3and 20x20x6mm3. Water absorption tests were conducted by immersion of the samples in a distilled water bath and the water uptake calculated by weight difference of the samples in the dry and wetted condition at different elapsed time. A three-dimensional mathematical model was developed to predict mass transfer during the water absorption inside the parallelepiped solid. Results of water absorption kinetic and moisture content distribution inside the composites showed the more favorable areas which presents delamination problems due the weakness of the fiber-matrix interface and consequently, reduction in the mechanical properties. It was found that the high water bath temperatures accelerate the absorption process and that the water absorption of the sisal reinforced polymer composite with 3 mm of thickness was faster than the with 6 mm of thickness.

Background: This in vitro study aimed to investigate and evaluate the values of water sorption and water solubility of four types of denture base polymers—3D-printed NextDent 3D Denture + (NextDent, 3D Systems, Soesterberg, The Netherlands), CAD/CAM milled Ivotion Base (Ivotion Denture System, Ivoclar Vivadent, Schaan, Liechtenstein), PMMA conventional Vertex BasiQ 20 (Vertex Dental, 3D Systems, Soesterberg, The Netherlands), and conventional heat-cured BMS (BMS Dental Srl, Rome, Italy)—which were subjected to artificial aging. Materials and methods: 200 specimens were created (n = 50), dried, and weighed accurately. They were immersed in artificial saliva (T1 = 7 days, T2 = 14 days, T3 = 1 month) and re-weighed after water absorption. After desiccation at 37 °C for 24 h and then at 23 ± 1 °C for 1 h, samples were weighed again. Next, thermocycling (100 h, 5000 cycles, 5–55 °C) was performed, and the water sorption and solubility were re-measured. IBM SPSS Statistics 0.26 was used for data analysis, revealing a direct correlation between water sorption and material type. Thermocycling at 55 °C increased water sorption for BMS and Vertex BasiQ 20. In conclusion, NextDent’s 3D-printed resin had higher water sorption values throughout the study. Water solubility averages decreased over time, reaching the lowest in the 30-day period for CAD/CAM milled dental resin Ivotion Base. The artificial aging had no effect on Ivotion Base and NextDent’s water sorption. Thermocycling did not affect the solubility of the materials tested. The conducted study acknowledges the great possibilities of dental resins for additive and subtractive manufacturing for the purposes of removable prosthetics in daily dental practice.
