This paper’s goal is to introduce the third step of EFOP-3.6.1-16-2016-00014. project on Faculty Engineering, University Szeged. In this period production technology composite material was chosen and a fatigue test machine developed tested. The paper shortly describes materials summarizes theory than it presents process development with several prototypes machine, some which were manufactured I...
statement of the problem: optical properties of the composite resins, concerning their translucency and thickness, are affected by discolored tooth structure or inherent darkness of the oral cavity. purpose: this study aimed to compare the translucency parameter (tp) of five different composite resins in different thicknesses and to evaluate their masking ability in black backgrounds. materials...
in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...
A novel porous composite material composed of hydroxyapatite, poly(vinyl alcohol) (PVA), and gelatin (Gel) was fabricated by emulsification. Scanning electron microscopy showed that the material had a well-interconnected porous structure including many macropores (100-500 microm) and micropores (less than 20 microm) on their walls. The composite had a porosity of 78% and showed high water absor...
